Wissmach Bronze Tr/White (color code 96-68) is a Prisma blend in COE 96 kiln glass, smoky bronze and soft white streaks in a 3mm sheet, tested for fusing compatibility.
Appearance Misty white fields carry horizontal drifts of smoky taupe bronze, warming to a soft peach blush where the two mingle. Bronze is named first, so it is the lead color of the blend, here thinning to haze wherever the white takes over. The streaking is unique to each sheet, so no two are identical.
Striking Wissmach notes that its Prisma colors may strike in the kiln, coming out a shade deeper or denser than the unfired sheet. When the fired tone matters, a small test chip is cheap insurance.
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 This blend 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 it pairs freely as a soft neutral.
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.
