Firing Stained Glass Question
Can You Fire Regular Stained Glass?
Mark Angus demonstration
I originally started doing stained glass before kiln work becme popular so of course I have lots of scrap glass. I purchased a kiln hoping to use this glass in the kiln or make frit to use.
I can’t seem to find any answers about the safety of not using special kiln glass.
As I’ve seen wine bottles being used in a kiln I don’t understand the difference in not using stained glass. Does anyone have information about this subject?
Hi Denise, yes, I can help you with this.
You’ll be pleased to know you’re absolutely correct in thinking that you can use your regular stained glass for firing.
All sheet glass has basically the same molecular make-up (give or take manufacturer’s special ingredients!) and can be fired successfully.
I don’t know if you’ve seen my section on painting glass? In it I have a standard firing schedule for paint, which might help you. You can find that particular page here. The firing program is towards the bottom, and there’s also a video that might help you.
You may need to add some annealing time to the firing, depending on the insulation properties of your kiln, and the size of the piece.
Good luck with all your bits of glass!
