I’d like to try my hand at using a drop ring. I have a 6″ square ring, does anyone know how much glass to use? I’d like to drop it approximately 3.5″ – 4.5″. I have a 5.75″ square tile I’d like to use, is this an ok size try?
Thanx for any suggestions you all might have.March 25, 2009 at 4:09 pm #11212AnonymousInactive
Square drop rings can be tricky – the rims have a tendency to fall through the hole.
Your best bet is to use the file width of the drop ring – so for a 6″ square I’d use a 6″ square piece of glass. Two layers should be fine.
All slumps – and drop rings especially – work best when you run them at low temps for longer times. That allows the glass to heat and stretch evenly.
As far as the height of the drop goes – you’ll need to peek in the kiln every so often at slumping temps to see where it is.

I took a drop bowl course several years ago but my notes are silent on how big I can make a hole in the concretized ceiling tile I bought.
More specifically, I have a 3/8 piece of glass about 11 inches square. I have a 12 inch square of the tile.
If I’m dropping the bowl 4 inches what is the limit to the size of the hole I can cut in the tile?
I fear that if I go near 9 inches the glass may pull away from the top of the tile and flop down the hole in the center of the tile onto the kiln shelf
I realize that a very cautious “lower slower” schedule will have to be used.
I’d appreciate any wisdom that might be lurking
