Wissmach Green Tea Transparent (color code 96-322) is COE 96 kiln glass, a pale sage green transparent in a 3mm sheet, tested for fusing compatibility.
Appearance A whisper of green, a pale sage tint that barely colors the light passing through it, with a faint surface ripple from the casting and the odd fine seed. A single layer reads almost neutral, and it takes doubled layers or a white backing to bring the green forward.
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 Green Tea is a copper bearing color on Wissmach's COE 96 chart, pale as it looks. Fired in direct contact with a sulfur bearing color such as String of Pearls, Oyster Pearl, Gold Tone or Honey, it can form a darker reaction line where the two glasses touch. Results vary by batch and firing, so run a small test tile first.
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.
