Glass slumping

Recommended Posts

Glass slumps at very low temps-I about 37 years ago tried to fire my own labels on beer bottles and all the necks slumped as well-So if memory serves its way below luster temps.

Google "slumping temperature of glass" you'll find many choices. I occasionally use glass threads, etc on some pots (decorative) and needed some help with temps. Started using a blog called "HOT OUT OF THE KILN'. They have a monthly newsletter as well. Might find it helpful.

Hey world,

 

I am loading a kiln for a bottle slumping and I forgot what cone to fire to, I think it might be ^012? Please help!

 

 

I do quite a bit of slumping. Just checked my firing log. Cone 015 with a 15 minute hold after a "fast" firing schedule. I just leave the kiln alone till it cools down to about 100
