Gold glass like lead glass?
« on: 10/08/2013 20:26:24 »
I like lead glass or crystal, is it possible to mix gold with glass as well? Would it have any good qualities?

I suspect the melting point of gold could boil glass, or reaction with silicon on contact.

You can put a little gold into glass

But the melting temperature of glass is too high for gold compounds and they convert back to the metal which would settle out.

You can make glass from pure silica and the glass you get has a fairly high melting point.
You could melt gold in a test tube made from silica glass.

Lead, by comparison forms an oxide which mixes with the other components of the glass and changes it's optical properties.
