Salviati Uranium Glass Plates

<< < (2/2)

glassobsessed:
They are made with gold leaf, the 'stripes' are where two sheets have overlapped. Aventurine is copper particles held in suspension within the glass (is that the right terminology Sue?) . To my ear gold and aventurine do not belong within the same expression. A further complication is when gold powder is used instead (often by Seguso) but all three techniques look quite different if you pay attention to the detail.

NevB:
You are right John, the gold swirls are made with a high carat gold, I should have said perhaps "aventurine effect".

chopin-liszt:
Aventurine is copper powder or tiny tiny particles of copper, suspended in glass, yes. :)
But it can come in other colours, rather than copper metal.
Green aventurine involves chromuim as far as I know. It turned up on some Monart by accident when a chromuim "scum" developed on the pot.
Sometimes copper aventurine can look green, if clear green enamel is over them.

But these plates contain gold foil. Nothing to do with aventurine at all. :)
