One of my colleagues was describing a process taught at Pilchuck glass school this summer.  The basic idea was the creation of a clay based on glass and a binder (or thickner).   She described the material as being a bit like children’s Play Doh.   You could shape this material, let it dry, and then kiln fire it.    She also said that one could use any variety of molds.   THIS IS VERY INTERESTING

I did a quick check on the web looking for “glass clay”.  I found a reasonable number of interesting URLs.

I found this thread on  If you have a few moments, please give it a read.

The thread is quite long and full of information BUT there is a big undercurrent of interlectual property rights, etc.    This may sound a bit familiar.

A thick paste made from powdered glass and some kind of binder that was kiln fired to create 3 dimensional glass objects was invented by the ancient Egypytians.

Thus you are all invited to look up “Egyptian Paste”.    You will find many recipes.

How does this relate to 3DP and/or PdV?   Well glass clay and egyptian paste could be very useful in rapid prototyping in other processes.   Check out   Anything that one could squeeze out of a syringe could be an RP material.    Guess what?   Two years ago, one of our students Nathaniel tried glass clay in the FabatHome system.   It worked fine. Great Fun.  Thus glass clay and egyptian paste are really a bit like pate de verre without a mold (in a somewhat similar manner as 3DP glass).
