Wissmach Turquoise Green Transparent (color code 96-50) is COE 96 kiln glass, a light minty aqua in a 3mm sheet, tested for fusing compatibility.
Appearance A pale aqua that leans green, like sea glass rinsed by the surf, passing plenty of light with only a few scattered fine seeds. One fired layer stays soft and misty, while doubling the layers deepens it toward a true turquoise.
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 Turquoise Green is a copper bearing color on Wissmach's COE 96 chart. Fired against sulfur bearing colors such as String of Pearls, Oyster Pearl, Honey, Yellow or the red and orange family, it can develop a darker line where the glasses meet. The effect varies batch to batch, so run a small test tile first, whether you want the line or want to avoid it.
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.
