Wissmach Classic Violet (color code 96-04) is COE 96 kiln glass, a soft lilac violet opaque in a 3mm sheet, tested for fusing compatibility.
Appearance A muted, dusty violet with a gentle gray softness to it, even in tone from edge to edge. As an opaque it blocks light, so it reads the same on a lightbox or a tabletop, which makes it a dependable mid value for florals, landscapes and layered work.
Striking Like the rest of Wissmach's Opaque and Prisma palette, this color may strike deeper or denser in the kiln. Plan on the fired result being a little richer than the sheet in your hand, and fire a sample chip when the exact shade matters.
Working notes Wissmach’s recommended full fuse schedule for a 6mm project made from two 3mm layers: heat at 300 degrees F per hour to 1225 F and hold 30 minutes, then 600 per hour to 1460 F with a 10 minute hold, cool as fast as the kiln allows to 960 F and hold 1 hour, then 100 per hour down to 700 F. These numbers come from Wissmach’s current published firing guidance. They are guidelines, not guarantees. Kilns differ, so fire a small test piece first.
Reactions Classic Violet is not flagged on Wissmach's COE 96 reactive chart. It sits next to any color in the line without forming a reaction line, so you can place it freely in a design without planning around chemistry.
Format and sizes Sold as a 3mm sheet in 8" x 10.5", 10.5" x 16" and 16" x 21" sizes. Choose your size from the options on this page.
Fusing and compatibility Tested compatible with other Wissmach COE 96 kiln glass. With glass from other makers, a matching COE number alone does not guarantee compatibility, so fire a test tile before committing a project.
