A friend came to me this weekend with a request. He has a fairly valuable insulator but it has a couple of large cracks in it which reduces the value significantly. The picture below isn't the exact piece but shows the type of damage I'm talking about.
He was wondering if I could "heat it up and melt it together". What we came up with was filling a container with plaster/silica mixture and submurging the piece is it. When it dries, place it in the kiln and fire it using a schedule for 3/4" thick glass.
Will this work? I'll try it with a less valuable insulator first. Has anyone done anything similar to this before?
I also can't see the piece, but I suspect that if you do this, if it actually works, if nothing else, the surface will not be the same as the original. You'll have to do alot of cold-working to get it back the way it was.
