Re: board (?) jewelry casting molds

I like your idea. We have a makerspace in Salt Lake City with a CNC router. The thing I might try, is to simply pour a flat slab of R&R investment, and carve it. If I find that it works, I will post the before and after shots. The stuff is so soft, it should carve nice.

Pate de Verre - Ballotini

I have a large amount of extra fine glass balls ballotini. It's small enough to be described as a powder. I would like to do a little experimentation using it for the clear base with which to mix powder colors for Pate de Verre. If I was to take "any" powdered glasses, i.e. fritted bottle ...

Refractory Materials

Does anyone know if "Spinel" ramming refractory material would be useful as a component in making your own investment for lost wax casting, or for bead release, or for any other "glass" use?:
Al2O3 89%
SiO2 0.5%
MgO 10%

I have a whole bunch available...

Re: How to polish a casted sculpture

Get a copy of the book: "The Joy of Coldworking" Everyone should have this book!

If you watch you local classifieds for "lapidary equipment" you may be able to find some useful tools. There may be a local rock collector's club, which is also a great source.

Re: Sticking Kilnwash, Better Kilnwash?

If you are making your own molds, and if you use an investment such as R&R 910 glass cast, you do not need any kiln wash. The glass releases beautifully!
