You’ve mastered the fundamentals of cutting and assembling glass, so what’s next? It’s time to add your signature touch, and for that, I always turn to Reusche glass paint. These versatile vitreous paints are a game-changer for adding incredible detail and depth to your work. Whether you’re creating subtle shading on a fused glass bowl or painting intricate patterns on a traditional stained glass panel, Reusche glass paints deliver the consistency and quality your art deserves. This guide will show you exactly how to use them to make your work truly stand out.

Key Takeaways

• Add Permanent Details with Reusche Paint: This professional-grade paint starts as a powder that you mix into a liquid. After painting your design, a kiln firing permanently fuses the color to the glass, creating a durable finish for stained and fused glass art.
• Proper Prep Ensures a Flawless Finish: Your success starts before you paint; always begin with meticulously clean glass and mix the paint powder with water and a binder to a smooth, cream-like consistency for an even application.
• Match Your Glass and Fire Correctly: Ensure compatibility by using Reusche paints with COE90 or COE96 glass. Firing your piece correctly, usually between 1300°F and 1450°F, is the final step that matures the colors and creates a strong, lasting bond.

What Is Reusche Glass Paint?

If you’ve ever admired the delicate, painted details on a piece of stained or fused glass, you were likely looking at the work of a glass paint. Reusche glass paints are a go-to for artists who want to add intricate designs, shading, and fine lines to their work. These paints are specially formulated to be fired in a kiln, where they permanently fuse with the glass surface. This process creates a durable, lasting finish that becomes part of the glass itself, rather than just sitting on top. It’s what gives painted glass that professional, seamless look.

Whether you’re working on a traditional stained glass panel or a modern fused glass dish, Reusche gives you the control to paint with precision. The paints come as a fine powder that you mix into a liquid medium, allowing you to create everything from transparent washes of color to opaque, detailed illustrations. It’s a fantastic way to add another layer of artistry to your projects, letting you move beyond just cutting and assembling glass. You can use them on many types of glass, including popular choices like COE90 glass and COE96. This versatility makes it a staple in many glass studios for adding that final, personal touch.

What’s It Made Of?

At its core, Reusche paint is a vitreous paint, which is a technical way of saying it’s designed to turn into glass when fired. Each color is a simple but effective mixture of two main components: finely ground glass and a specific pigment oxide. The ground glass acts as the base, ensuring the paint can melt and fuse seamlessly with your project in the kiln. The pigment oxide is what gives the paint its color. Think of it like making a cake; the ground glass is the flour, and the pigment is the cocoa powder or vanilla that gives it its unique flavor and appearance. This composition is key to its permanence and professional finish.

What Sets Reusche Apart?

Reusche has been a trusted name among glass artists for generations, and for good reason. The quality and consistency of their paints are hard to match. Because the powder is so finely ground, it allows for incredible detail and smooth application, which is essential for techniques like shading, tracing, and creating delicate patterns. These paints are specifically made for both stained glass and fused glass projects, so you know they are formulated to perform reliably under heat. This reliability means you can spend less time worrying about how your colors will turn out and more time focusing on your creative vision.

Are There Lead-Free Options?

Safety is always a priority in the studio. Traditionally, many glass paints contained lead and other heavy metals to achieve certain colors and effects. While these are still used by some artists for historical restoration, many prefer to work with safer materials. Reusche understands this and offers a great selection of lead-free and cadmium-free paints. These modern formulations provide beautiful, vibrant colors without the health concerns associated with heavy metals. Choosing these options is a great way to keep your studio environment safer for you and anyone else who shares your creative space, without compromising on the quality of your finished work.

Choosing Your Reusche Paints for Glass

Reusche offers a fantastic range of paints, each with its own unique purpose. Whether you’re working on a traditional stained glass panel or a modern fused piece, there’s a Reusche paint that will help you bring your vision to life. Getting to know the different types will help you choose the right one for your project and achieve the exact look you’re going for. Let’s break down the main categories and what makes each one special.

Getting Started with Vitreous Paint

At their core, Reusche’s vitreous paints are a beautiful blend of finely ground glass and pigment oxides. This composition is what gives them their vibrant, lasting color. These paints are designed to be fired in a kiln, where they permanently fuse to the glass surface. This makes them an excellent choice for detailed work on stained glass projects that need to stand the test of time. One of the best parts is their versatility; you can easily mix different vitreous paints to create a completely custom palette, giving you endless creative freedom for your designs.

When to Use Traditional Glass Stainers

Reusche has earned a stellar reputation among artists who practice traditional glass painting, and for good reason. These paints are known for their exceptional quality and consistency, making them a reliable choice for techniques that have been passed down through generations. If you appreciate the rich history of stained glass and want to use materials that honor that craftsmanship, Reusche’s traditional stainers are a perfect fit. They allow you to connect with the art form on a deeper level, using paints that have long been trusted by masters of the craft.

Creating Effects with Enamels and Specialty Paints

Beyond the classic vitreous paints, Reusche also provides a wonderful selection of enamels and specialty paints. These are specifically formulated for artists working with fusible glass, like COE90 glass and COE96. If your goal is to add intricate patterns, delicate lines, or opaque layers to your fused glass art, these paints are your go-to. They open up a whole new world of design possibilities, allowing you to combine the fluid beauty of fused glass with the precision of painted details. Think of them as the perfect tool for adding that final, artistic touch to your kiln-formed pieces.

Exploring the Full Product Line

Reusche’s product line is impressively deep, giving you a ton of options to explore. This variety is a huge advantage because it means you can find the perfect paint for your specific project, whether you’re detailing a traditional stained glass window or adding flair to a modern fused piece. Getting to know the different series—from their classic vitreous paints to their fusible enamels—is the best way to make an informed choice. Taking a moment to understand which paint is formulated for your glass and firing schedule will help you achieve the exact look you’re going for and bring your creative vision to life with confidence.

Special Bending Colors and Other Options

The color palette alone is incredible, with over 120 different glass paints and enamels available. This huge selection means you can often find the exact shade you need right out of the jar. Reusche also offers special “Bending Colors,” which are formulated to mature at the lower temperatures used for slumping and draping glass over molds. This is perfect for adding color to shaped pieces without risking a full fuse. While prices can range from around $10 to over $100 depending on the color and type, this variety ensures you’re never limited by your materials when inspiration strikes.

How to Use the Reusche Color Palette

One of the most exciting parts of working with Reusche is the sheer variety of colors at your fingertips. The palette is extensive, covering everything from rich Ambers and deep Blues to vibrant Reds and crisp Whites. You’ll also find a full spectrum of Browns, Greens, Yellows, and even metallics like Silver. This broad selection means you can find the perfect shade for any project without having to mix it from scratch, unless you want to. It gives you the power to create pieces with incredible depth and nuance, whether you’re aiming for photorealism or abstract expression.

How to Mix Custom Colors

Creating your own custom colors with Reusche paints is surprisingly simple. The paints come in a powder form, which you’ll mix with a liquid medium before applying to your glass. Most artists use a simple combination of water and gum arabic to create a smooth, paintable consistency. This process gives you complete control over the hue and transparency of your colors. You can experiment with different ratios to achieve everything from a light, watercolor-like wash to a thick, opaque layer. It’s a straightforward way to make your glass art truly one-of-a-kind.

Project Ideas for Reusche Glass Paint

Once you have your paints, the real fun begins. Reusche paints are incredibly versatile, opening up a world of creative possibilities for both traditional and contemporary glass artists. Whether you’re looking to add fine details to a classic piece or create bold, modern designs, these paints can help you bring your vision to life. Here are a few project ideas to get your creative gears turning, from timeless stained glass techniques to modern kiln-fired creations.

Painting on Traditional Stained Glass

Reusche paints are a game-changer for traditional stained glass work. Use them to paint fine details like faces, lettering, or delicate patterns that would be impossible to create with cut glass alone. Think of them as your secret weapon for adding depth and realism. You can apply these paints to clear or colored glass to create shading and intricate imagery, mimicking historic cathedral windows. This technique is perfect for creating stunning window hangings, cabinet inserts, or decorative panels. If you’re new to this, start with a simple suncatcher to get a feel for how the paint works with light.

Adding Color to Modern Fused Glass

If you love the sleek look of fused glass, Reusche paints are an amazing partner in the studio. You can paint designs directly onto your COE90 glass before firing. When you fire the piece, the paint permanently fuses with the glass, becoming part of the final object. This allows you to create vibrant, durable patterns that won’t chip or fade. It’s a fantastic method for making one-of-a-kind jewelry, colorful coasters, or small, abstract art pieces. Experiment with layering colors or using fine lines to create designs with incredible precision.

Designing Kiln-Fired Decorative Art

Take your glass art beyond flat panels and explore three-dimensional decorative pieces. With Reusche paints and a kiln, you can transform simple glass objects into functional works of art. Imagine painting a floral design onto glass plates or creating custom tiles for a kitchen backsplash. You can also paint on glass that you intend to slump into a shape using glass molds. This process lets you create custom bowls, platters, and light fixtures. The kiln-firing process not only makes the paint permanent but also deepens the colors, giving your finished piece a professional, polished look.

How to Mix and Apply Reusche Glass Paint

Getting your Reusche paint ready for your project is a straightforward process, but mastering the mix is key to achieving beautiful, lasting results. Once you have the right consistency, you can move on to the fun part: painting your design and bringing your vision to life on glass. Let’s walk through the essential steps, from mixing your first batch to applying detailed layers.

How to Create Your Basic Paint Mix

Reusche Glass Paint comes as a fine powder that you’ll need to prepare before you can use it. The classic recipe is simple: just mix the paint with water and a small amount of gum arabic. The water turns the powder into a liquid paint, while the gum arabic acts as a binder. This helps the paint flow smoothly from your brush and stick to the glass surface while you work. Without a binder, the paint can be difficult to control and may not adhere properly before it’s fired in a kiln. Think of gum arabic as the secret ingredient that makes the paint workable and your application process much easier.

How to Get the Perfect Paint Consistency

Your goal is to mix the paint to a consistency that feels right for your project. A good starting point is to aim for something similar to heavy cream. This texture is usually fluid enough to spread in smooth, even strokes but thick enough that the color remains rich and opaque. If your mix is too thin, the color might look washed out; if it’s too thick, it can be clumpy and hard to apply, especially for fine details. Don’t be afraid to experiment. Add your water slowly and mix thoroughly until you get a feel for the consistency that gives you the best control and coverage.

How to Choose Brushes and Apply Your Paint

The brushes you choose will have a big impact on your final piece. For covering large areas with a smooth coat of color, flat brushes are a great choice. For intricate lines, lettering, or delicate patterns, you’ll want a set of fine-tipped detail brushes. Having a variety of brush shapes and sizes on hand allows you to switch between broad strokes and precise details seamlessly. When you apply the paint, use confident, even strokes. Whether you’re creating a modern pattern on a fused glass dish or painting a classic scene for a stained glass panel, the right brush makes all the difference.

How to Layer, Shade, and Add Detail

One of the best ways to create depth and dimension in your glass art is by layering colors. The key is to let each layer dry completely before adding the next one. This prevents the colors from smudging or becoming muddy. You can build up transparent colors to create beautiful shading effects or add fine opaque details over a base coat. This technique is perfect for adding shadows, highlights, and textures that make your artwork pop. Once you’re happy with your design and the paint is dry, the piece is ready for firing, which will permanently fuse the paint to the glass.

Prep Your Glass and Avoid Common Mistakes

You’ve got your beautiful Reusche paints and a vision for your project. But before you dip your brush, a little prep work can make all the difference between a masterpiece and a frustrating mess. Taking the time to prepare your surface and test your materials is a key step for professional-looking results. Let’s walk through the simple steps that ensure your paint looks its best and lasts, so you can avoid common frustrations.

How to Properly Clean Your Glass

The secret to paint that sticks is a perfectly clean surface. Any oils from your fingers, dust, or residue can prevent the paint from adhering, leading to chipping or peeling after firing. To get it right, do a two-step clean. First, wash your glass with soap and water. Once it’s dry, give it a final wipe-down with rubbing alcohol on a lint-free cloth to remove any lingering oils. Taking a few minutes to properly prepare glass for painting is the best insurance for a flawless, durable finish.

Common Application Mistakes to Avoid

When applying glass paint, less is more. A frequent issue is applying the paint too thickly. A heavy coat might seem like a good way to get opaque color, but it often leads to drips, an uneven texture, and cracking during firing. Instead, apply multiple thin, even coats, letting each layer dry completely before adding the next. Your choice of brush matters, too; many artists prefer synthetic brushes for their smooth application on glass. Avoiding these common mistakes when painting glass gives you much more control over the final look of your piece.

Why You Should Always Test Your Colors

The color in the jar is rarely the exact color you’ll see on your finished piece. The glass itself, your studio lighting, and the heat from the kiln can all alter a paint’s appearance. This is why you should always test paint colors before starting your main project. Keep a few scraps of the same glass on hand. Paint a small swatch of each color onto a scrap piece and run it through a full firing cycle. This simple test saves you from unpleasant surprises and ensures the colors in your finished artwork are exactly what you envisioned.

Will Reusche Paint Work with Your Glass?

Before you dip your brush, let’s talk about making sure your paint and glass are a good match. It might sound technical, but getting this right is the key to a piece that lasts. The main thing you need to know about is the Coefficient of Expansion, or COE. This number tells you how much your glass expands and contracts when heated and cooled. Using a paint that isn’t compatible with your glass’s COE can lead to cracking or peeling, and we definitely want to avoid that heartbreak after you’ve put so much work into your art.

Checking for COE90 and COE96 Compatibility

Reusche paints are specifically formulated to work beautifully with glass that has a COE of 90 or 96. Think of COE as the glass’s “stretchiness” when it gets hot. If your paint and glass don’t stretch at the same rate in the kiln, the paint can flake off or even cause the glass to crack. It’s crucial to know what you’re working with. Generally, COE90 glass is a go-to for fusing projects, while COE96 glass is also popular for fusing and stained glass work. Always double-check the COE of your glass sheet before you start painting to ensure your masterpiece comes out of the kiln looking just as you imagined.

How to Use Reusche Paints on Stained Glass

Reusche paint is a fantastic choice for adding intricate details and vibrant color to your stained glass projects. Its formulation is designed to permanently bond with the glass surface during firing, creating durable, lasting designs that won’t fade. For the best results, I recommend applying the paint in thin, even layers. You can always build up color, but starting thin prevents bubbling or an uneven finish. Because it’s so versatile, you can use it for everything from fine line work and shading to broader washes of color. Whether you’re a seasoned pro or just starting your stained glass journey, Reusche gives you the control and quality you need to bring your vision to life.

How to Fire Reusche Glass Paint

Firing is where the real magic happens. After you’ve spent time carefully mixing and applying your paint, the kiln is what transforms your work from a delicate design into a permanent, vibrant piece of art. It can feel a little nerve-wracking to hand your piece over to the heat, but don’t worry. Once you understand the basics of firing schedules, you’ll feel confident pulling beautiful, perfectly fused glass art out of your kiln. This process ensures your painted details become one with the glass, creating a durable and brilliant finish that will last a lifetime.

What Are the Ideal Kiln Temperatures?

Getting the temperature right is the key to making your Reusche paints look their best. The manufacturer recommends firing their paints between 1300°F and 1450°F. In this range, the paint particles melt and permanently fuse to the glass surface. Firing too low might result in a weak bond, while firing too high can cause the colors to burn out or the glass to deform. The exact temperature you choose will depend on your specific project, the type of glass, and the colors you’re using. Having reliable kilns that can hold a precise temperature is essential for getting consistent, professional results every time.

Easy Firing Schedules to Follow

Every artist’s firing schedule can be a little different, but here is a great starting point for working with Reusche paints. Think of this as a reliable recipe you can tweak as you get to know your kiln and materials.

1. Ramp 1: Heat at 200°F per hour up to 300°F.
2. Hold 1: Keep it at 300°F for 30 minutes. This slow start allows any moisture from the paint to safely evaporate without causing bubbles.
3. Ramp 2: Heat at 300°F per hour up to 1350°F.
4. Hold 2: Hold the peak temperature for 10 to 15 minutes. This is when the paint matures and fuses with the stained glass.
5. Cool: Let the kiln cool down naturally. Don’t peek, as opening the door too soon can cause thermal shock and crack your piece.

Always test a new schedule on a small scrap piece first.

How Firing Transforms Your Piece

The change that happens inside the kiln is truly remarkable. Before firing, the dried paint is a fragile, powdery layer on top of the glass. After a successful firing, it becomes a completely new thing. The heat transforms the paint into a glossy, hard layer that is chemically bonded to the glass surface. This process is what brings the colors to life, making them rich, deep, and luminous. Your design is no longer just on the glass; it’s part of the glass. This creates a durable finish that won’t scratch off or fade, so your beautiful artwork can be enjoyed for years to come.

Essential Tools and Supplies for Your Studio

Getting beautiful results with Reusche paints is as much about your tools as it is about your technique. Let’s walk through the essential gear you’ll want to have on hand before you start your next glass painting project. Equipping your studio correctly sets you up for success and makes the creative process so much smoother. Having the right supplies ready means you can focus on your art without interruption.

The Best Brushes and Tools for Painting on Glass

When you’re working with Reusche paints, the quality of your brushes really matters. High-quality synthetic brushes are a great choice, as they help you apply the paint smoothly and evenly without leaving stray bristles behind. It’s helpful to have a few different types in your collection. Think of flat brushes as your go-to for covering larger areas with a consistent coat of color. For all the delicate work, from fine lines to detailed shading, you’ll want a set of fine-tipped detail brushes. Don’t forget a palette knife, either. It’s not just for mixing colors on your palette; you can also use it to apply paint for interesting textural effects.

Choosing the Right Kiln and Molds

To permanently set your painted designs and make them a durable part of the glass, a kiln is an absolute must-have. This is what allows the paint to fuse to the glass surface, typically at temperatures between 1300°F and 1450°F. Investing in a reliable kiln gives you control over the firing process, which is key to achieving vibrant, lasting colors. If you want to create three-dimensional pieces, molds are your best friend. They provide the structure for slumping and draping your painted glass into bowls, plates, or sculptural forms, opening up a whole new world of creative possibilities.

Casting, Flameworking, and Display Materials

As you grow more confident with painting, you might feel inspired to explore other glass art forms like casting or flameworking. While Reusche paints are designed for surface application, they can be the perfect finishing touch for pieces created with these methods. For example, you can add intricate, painted details to a cast glass sculpture after it comes out of the kiln. The same principles of color theory and fine-line work apply, allowing you to add another layer of artistry to your three-dimensional work. When you’re ready to experiment with creating shapes, you can explore molds to form everything from simple bowls to complex figures. Once your piece is complete, don’t forget to consider how you’ll display it. A high-quality stand or frame enhances the beauty of your work and presents it as the piece of art it is.

Where to Find Reusche Glass Paint

Finding the right supplies shouldn’t be a treasure hunt that takes you away from your art. When you’re ready to start painting, you want to know exactly where to go. The great news is that Reusche’s professional-grade glass paints are readily available online, making it easy to stock your studio with every color you need for your next project. Whether you’re working with COE90 glass or creating a traditional stained glass panel, you can find these paints from specialty suppliers who understand the needs of glass artists. Let’s look at where to find them and what you can expect to pay.

An Important Update: The Transition to Fuse Master

There’s some big news in the glass painting world that you’ll want to be aware of. The beloved Reusche line of enamels and glass paints has found a new home. Fuse Master, another well-respected name in the industry, has officially taken over production from Schilling Inc. I know changes like this can be a bit disruptive, especially when you rely on specific materials for your art. This transition means that going forward, Fuse Master will be the go-to source for the Reusche products you know and love. It’s a significant shift, and it comes with a few temporary hurdles as they get everything up and running.

Temporary Production Delays

The most immediate impact of this change is a temporary pause in production. Fuse Master has announced that it will take them “several weeks” to get the necessary supplies and set up their manufacturing process for the Reusche line. This means that for a short period, these paints will be unavailable to order, both for artists and for suppliers like us. We know how frustrating it can be when a key material is out of stock. We’re keeping a close eye on the situation and will be ready to restock as soon as production is rolling again. If you have questions, please feel free to contact our team. In the meantime, it’s a good opportunity to take stock of your current supplies or perhaps experiment with other techniques.

How to Contact Fuse Master for Inquiries

With this transition, the point of contact for all Reusche-related questions has changed. If you have specific questions about product availability, technical details, or when you can expect to see paints back on the shelves, you’ll want to reach out directly to Fuse Master. They are now managing all inquiries regarding the Reusche line. According to their website, they are working hard to get production started as quickly as possible. You can find updates and contact information on the Reusche page of the Fuse Master website. They will be the best source for the most current information as they navigate this transition period.

Are Reusche Paints Worth the Price?

Budgeting for supplies is a practical part of any artistic practice. Reusche glass paints are an affordable investment in quality, with prices that are accessible for both hobbyists and professional artists. Typically, you can expect a standard 1-ounce container to cost between $12 and $32, depending on the specific pigment. Some specialty colors, like silver stains, can be priced higher due to the raw materials involved. It’s always a good idea to keep an eye out for sales, as you can often find popular colors at a reduced price. This allows you to stock up on your most-used shades or experiment with a new color without a big financial commitment.

Understanding the Full Price Range

While the general price for Reusche paints is quite reasonable, it’s helpful to understand why you might see some variation across the color palette. Most 1-ounce containers fall within the $12 to $32 range, but you’ll notice that certain specialty colors, particularly silver stains or rich reds, can be priced higher. This difference comes down to the raw materials used to create the pigment. Some colors require more expensive or rare minerals to achieve their specific hue and brilliance. This isn’t unique to glass paints; it’s a common factor in professional-grade art supplies. By understanding this, you can budget for special projects, like a detailed panel for a stained glass window, while still stocking up on everyday colors. It’s always a smart move to keep an eye out for sales to get the best value on your favorite shades.

Artist Resources and Learning Opportunities

Working with a new material is an exciting process of discovery. As you get more comfortable with Reusche paints, you might be looking for ways to deepen your knowledge, connect with other artists, and find inspiration for your next project. The journey of an artist is one of continuous learning, and thankfully, there are plenty of resources out there to support you. From historical documents that connect you to the craft’s legacy to hands-on workshops that sharpen your skills, here are a few avenues to explore as you continue to grow.

Historical Catalogs and Guides

For a fascinating glimpse into the history of glass painting, you can explore old manufacturer catalogs. These aren’t just product lists; they’re time capsules that show how techniques, styles, and color palettes have evolved. Some suppliers have made these historical documents available online, like this old Reusche Glass Stainers’ Catalog, which you can download as a PDF. Studying these guides can spark new ideas and give you a deeper appreciation for the materials you’re using. It’s a wonderful way to connect with the long line of artists who have used these same paints to create beautiful, lasting works of art.

Finding Workshops and Classes

While you can learn a lot from reading and watching videos, there’s no substitute for hands-on instruction. Taking a workshop is one of the best ways to get personalized feedback and master tricky techniques, like getting your paint consistency just right. Many local art centers and glass studios, like Pacific Art Glass, offer classes for artists who want to learn new skills. These workshops are also fantastic opportunities to meet other glass enthusiasts in your area, share tips, and build a creative community. Search for glass art classes near you—you might be surprised by what you find.

Options for Wholesale Pricing

As your skills grow, you might find yourself using more supplies, either for a growing collection of work or for teaching others. If you’re starting to sell your art or host your own workshops, it’s smart to look into options for buying materials in larger quantities. Many suppliers offer special pricing for businesses or artists who are buying in bulk, which can make a big difference in your bottom line. If you’re scaling up your studio, it’s always worth asking your favorite supplier about their programs for professional artists or educators. This practical step can help support your creative passion as it grows into a sustainable practice.

Frequently Asked Questions

Is this paint permanent? Yes, but only after it has been properly fired in a kiln. The heat is what permanently fuses the paint to the glass, making it a durable part of the surface that won’t scratch or fade over time. Before it goes into the kiln, the dried paint is just a delicate layer that can be easily wiped away, so the firing step is essential.

What do I mix the paint powder with? The most common and effective medium is a simple mixture of water and gum arabic. The water turns the powder into a liquid, while the gum arabic acts as a binder to help the paint stick to the glass and flow smoothly from your brush. You can adjust the amount of water to create different consistencies, from a thin, watercolor-like wash to a thick, opaque paint.

Why did my paint crack or flake off after firing? This frustrating problem usually points to one of a few things. The most common reason is that the paint was applied too thickly, causing it to crack under the stress of the heat. Another possibility is that the glass wasn’t perfectly clean before you started painting, as any oil or dust can prevent a good bond. It could also be an issue of compatibility if the paint and glass don’t expand and contract at the same rate.

Can I use this paint on any type of glass? Reusche paints are specifically designed to work with most art glass used for fusing and stained glass, particularly glass with a COE of 90 or 96. Using it on glass with an unknown or incompatible COE can cause problems like cracking during the cooling process. It’s always best to stick with glass you know is compatible to ensure your finished piece is stable and beautiful.

What temperature should I fire my painted glass at? The ideal firing range for Reusche paints is between 1300°F and 1450°F. The exact temperature you choose will depend on your specific kiln, the type of glass you’re using, and the final look you want to achieve. I always recommend running a small test piece with your chosen colors and glass to see how they react to your firing schedule before you commit your main project to the heat.
