Wissmach Crystal/ Garden Green (color code 96-56) is a Prisma blend in COE 96 kiln glass, a light spring green wash over clear in a 3mm sheet, tested for fusing compatibility.
Appearance A pale, airy green that reads like new spring growth, with the garden green drifting in soft trails through the clear rather than forming hard stripes. Because crystal is the first color in the name and the more dominant, the sheet stays light and passes plenty of light, with only scattered fine seeds. The streaking is unique to each sheet, so no two are identical.
Striking Like Wissmach's other Prisma blends, this one may strike, firing out a little deeper and denser than the unfired sheet. Fire a sample chip when the precise 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 This blend carries the copper marker on Wissmach's COE 96 chart. In direct contact with sulfur bearing colors such as String of Pearls, Oyster Pearl, Honey or Yellow, it can form a darker reaction line where the glasses meet. Results depend on batch and firing, so test the pairing first either way.
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.
