square slumping mold

I need to make a square serving bowl approx 10-12 inches across and so far haven't found a source. I'm wondering if it would slump into that size square bowl or whether it would need to be a drop out mold. Any help or sources would be appreciated. Linda

You could try cutting a square out of the center of a 12" piece of ceramaguard, or several layers of J-100.

This would give you something that looked like this:

Kim,

I see you're in the Tampa area. Do you order from Art Glass House?

If so, they have a square slumper in their catalogue. The 12" slumper is #30-8637. I've used it on many occasions and am pleased with it.

Wow! What a great looking piece! It seems to glow from within. Makes me want to touch it to see if it feels as glossy as it looks.

More like this, please.......

If you want a serving vessel with a square edge, and a square center recess isn't necessary, just use a round form. Disadvantage is the size the form takes up in the kiln, since the diameter of the form needs to be the point to point measure of the square. If you are only making one, you can also do it as a dropout, either using the previously mentioned board or other material, or stacking glass, covering with thinfire, and using that as the form. It can be a little tricky, but I have done it many times with success. Same effect can be acheived using flat steel stock, laid up so corners overlap, and also covering with thinfire. Good luck.

Hi Judy.
Yes, I am in the Tampa area. Funny, I contacted Art Glass House a week ago to set up an account with them. It is a 2 hour ride for me - so I could order, go pick up, stop over in Coco for lunch and then head home. I am always up for a road trip!!

Where are you?
