Techniques for Collectorsmaking goldstone?

17th Dec 2007 17:28 UTCTim Jokela Jr

A friend of mine is a wizard at crystal growing. I thought that a fun little task for him would be trying to create goldstone - the lapidary material that's just glass with minute copper flecks. Backstory being it was invented by Italian monks and the formula is long lost or somesuch nonsense.


I'm wondering if it's a simple as mixing molten glass with a bunch of copper powder, anybody out there with any ideas?

(Idly thinking about melting glass - sounds fun, eh?)

HI Tim,

Please see the article DR wrote on this subject.

The "copper flecks" in goldstone are discrete euhedral xls. Simply mixing powdered copper into molten glass probably won't achieve that result. But I would love to hear about your friends results if you can chat him up to give it a try!


Wish I had a proper furnace here, 'cause I've wanted to experiment with formulations to make goldstone for more than a year.

Well I'll be damned, that's a nifty bit of work, Dan. Formula seems simple enough, now to talk my old buddy into building a wee furnace in his back yard!

Sounds like an interesting project. My sister has all the kit needed to do this, so I might ask her if she's up for the challenge of trying this.
