Frax paper/ dams
Posted: Wed Sep 17, 2003 9:27 pm
OK this will involve your imagination. Imagine a series of cast rings. I want to pre cast the rings, polish etc. Then put these rings inside a vessel form. So you have a solid cast vase with rings inside.
The trick is that I want the rings to be a different color from the vase. They don't actually have to fuse to the vase, but I can imagine the machining to get the rings in IF I just cast them seperately.
My idea is to cast the rings, then make the wax vase, fit the rings with frax paper between the rings and the wax. Then after it's in the plaster, the wax would go, the frax would be bonded to the plaster.
Then when I fire it up, the frax paper would contain the rings while the mold fills with glass.
I would love to have the rings contained and fill the mold hot, but I'm willing to settle for filling the mold with frit, to avoid the Void , reduce the stress on the frax from molten glass (the rings) on one side and a void on the other.
Do I just have to submit to hours of dremel work, or is this possible?
Maybe I could use copper plates, but I still worry about leakage (and scale). And the copper plates would be another design element.
There are more ideas than time, but I'm focused on this one currently.
Thank for your help
