Wissmach Sage Leaf Transparent (color code 96-78) is COE 96 kiln glass, a soft gray green in a 3mm sheet, tested for fusing compatibility.
Appearance A muted, gentle green with a gray cast, close to the underside of a sage leaf, quiet rather than grassy. The sheet passes light softly and carries a lightly rippled surface texture with only sparse seeds. It works well anywhere a botanical neutral is needed, holding its own without shouting.
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 Sage Leaf is a copper bearing color on Wissmach's COE 96 chart. Fired in direct contact with sulfur bearing colors such as String of Pearls, Oyster Pearl, Honey or the red and orange family, it can form a darker copper sulfide line where the glasses meet. Results vary by batch and firing, so test the pairing first when it matters.
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.
