Wissmach Striker Glass

All Wissmach 96 OPAL glass is striker. Strikers are glass styles with the potential for color change or opacity difference. When fired in the Kiln the glass strikes due to the ingredients that make up the specific color as the glass fires in the Kiln the ingredients mature. Strikers generally strike at or near a full fuse. For Wissmach glass, a full fuse is 1450 degrees F. Striking may also be seen slightly below this temperature.

Wissmach Luminescent Coating

Similar to iridescent coatings, but not quite the same. Use luminescent glass to create different effects depending on the way you fire it.
You can fire Luminescent Glass:

• Coated side down onto a kiln wash dusted fiber shelf and the coating will intensify.
• Coated side down onto a kiln washed shelf or shelf paper and it will still look intense but different.
• Coated side up and the luminescent coating will stay on darker colors if you fire no higher than 1410 °F, but will fade away on lighter colors giving the glass a beautiful sheen.
• Cover the coated side with a piece of clear and the coating will fade away completely.
