Liquid Bright Colors

Ceramic lustres are precious metals in liquid form that can be painted on to fired ceramic surfaces to produce metallic and iridescent effects.

Details

Liquid bright precious metal colors are micro-thin coatings, mainly of gold, platinum and palladium, applied onto already-fired glaze surfaces and fired around cone 018, 1350F. The metals are dissolved into hydrocarbon solvents with resin hardeners. They are made from mixes of strong solvents so safety precautions in working with them must not be ignored.

Books:

Ceramic Colours and Pottery Decoration by Kenneth Shaw, published by Maclaren and Sons Ltd., London, 1962, reissued 1968.
Lustres by Margery Clinton, published by BT Basford Ltd. London, 1991. This book covers how to make and use lustres.

Here is an example of research done by one artist researching various brands of gold luster, evidently they are not created equal. It is apparent you will need to be willing to do testing.

Colorobbia BRIGHT GOLD Contains 10-11% gold by weight.
BRIGHT GOLD (From ITALY – 24% / 20 karat gold – a true gold, Liquid form (DBA China Paint supply)

Safety Data Sheet for liquid bright gold - Duncan
Many solvents are listed. However the word "firing" appears only once (with a recommendation for a venting system).

Dresden Liquid Bright Gold safety data sheet
More than 15 solvents are enumerated, each having its own hazards. However, there is no obvious mention of hazards related to firing it once dry.
