This 5.25 by 4 inch sheet gathers about ten marine subjects drawn in dense black line work with fine crosshatching, in the manner of 19th-century natural history engraving. The subjects include a tusked narwhal, a sand dollar, a starfish, a crab, a whale, two octopuses with curling tentacles, a compact fish, and a squid trailing long arms, along with a lighter outline figure. Each image sits cleanly against a clear background, making the designs easy to cut apart and place individually. Individual decal sizes run roughly 1 inch to 2 inches, giving a variety of scale within a single sheet.
These are water-slide fusible glass decals. To apply, soak each decal briefly in water until the printed film releases from its paper carrier, then slide it into position on clean, dry, pre-fired glass. Smooth out any water and air bubbles with a soft tool or fingertip, allow the piece to dry fully, and fire in a kiln. Because the decal bonds to the surface of existing glass rather than fusing as a glass layer within a stack, no single COE applies: the sheet works equally well on 90, 96, float, and other glass types. The fired result adds graphic dimension to pendants, small panels, platters, and other kiln-formed pieces.
What is a water-slide decal and how does it differ from fusing glass?
A water-slide decal is a printed film that transfers from a paper carrier to a glass surface after a brief soak in water. You apply it to glass that has already been fused or shaped, not to raw glass in a stack. Because the decal sits on top of the finished glass surface, COE compatibility is not a factor the way it is when fusing two glass sheets together.
Do these decals work on any COE glass?
Yes. Since the decal fires onto the surface of pre-fired glass rather than being incorporated into a fused stack, it is compatible with any COE. Clean the glass surface thoroughly to remove oils and residue before applying, as surface contamination is the most common cause of adhesion problems.
How many designs come on the sheet, and how large are they?
Each sheet measures 5.25 by 4 inches and holds about ten individual sea life designs. The individual images run roughly 1 inch to 2 inches. You can cut the sheet apart to use a single motif or arrange several together on one piece of glass.
What peak temperature should I target?
The firing range for this single-color decal sheet is 1240 to 1370 degrees Fahrenheit, kept toward the lower end to preserve density. See Working Notes below for the full suggested schedule.

Working Notes
Apply each decal to a clean, grease-free surface of pre-fired glass. Soak the decal in room-temperature water until the film slides freely from its paper backing, then position it on the glass and smooth out all water and air bubbles with a soft squeegee or your fingertip. Let the piece dry completely before placing it in the kiln. Avoid handling the dried decal surface, as oils from skin can interfere with adhesion during firing.
Suggested Firing Schedule (a suggested starting point only):
On fused glass this single-color print fires to a final range of 1240 to 1370 degrees Fahrenheit, held about 10 minutes and kept toward the lower end to preserve density. Ventilate the kiln well up to 1000 degrees and fire slowly below 500 degrees.
50 degrees per hour to 185 degrees, hold 20 min.
150 degrees per hour to 300 degrees, hold 15 min.
250 degrees per hour to 500 degrees, hold 15 min.
600 degrees per hour to 1000 degrees, hold 10 min.
Then to 1240 to 1370 degrees, hold about 10 min.
Anneal for the thickness of your glass.
This schedule is a starting point, not a guarantee of results. Every kiln fires differently. Test a small piece first and adjust peak temperature, ramp rates, and hold times to suit your kiln, glass thickness, and desired finish.
