Hi Mike from Italy,
I have been eagerly waiting for someone to answer your question. Although I don't have any direct experience to share, I have been thinking about a possible solution.
The first thing I would try is a Cordierite kiln shelf or pizza stone. Inexpensive, easy to find and proven in the kiln. It is machinable and can be polished and fits your other criteria. You may even have a broken kiln shelf around your studio to try.
There are other hi-tech ceramics available, Macron (a Corning product) is something that you could research. Google 'machinable ceramics'.
If this works for you, I would love to hear your results.
Cheers,
Jen

I know it is a difficult question the mine.
It is important to find a right material to able to be carved and that glass not stick on it even if using wet kiln wash or BN.
other advices from other friends-members?

Hard ceramics are going to be really difficult to machine. Just about everything else is pretty nasty without excellent dust collection. You might have luck with this material http://www.glasscolor.com/products/defa ... 50&pID=145

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.
