Organometallic liquid gold luster
What is the chemical process for making organometallic gold and silver liquid lusters, similar to those produced by Engelhard and sold by Duncan and
Hanovia companies? These liquids are applied to a surface such as glass and then fired at a high temperature to deposit the pure precious metal.

Different subject a bit, but have you ever melted copper and silver together and make a ring. I made this rough ”ACS” ring that turns gold or
bronze with well water because of the sulphide. Ag for silvery, Cu for copper and S(-2) for sulphide. It has a nice crude cyclooctane shape. And
discolours latex gloves where the ring is, so maybe it sublimates and this can be used to coat as a metallic surface. The patina is water soluble
(AgCuS) comes off in water with the sink from hand washing to some extent to go a nice pure silver colour.
Happy Holidays!

The general description of the formulation of these lustres is a metal oxide suspended in an alkyd resin. The carbon rich resin acts as a reductant as
it burns off, the metal oxides are usually precious metals so persuading them to give up their oxygen isn't too much of a challenge.

Can someone direct me to a patent or published process for formulating organometallic lusters? I am interested in pursuing the challenge of making
gold and platinum lusters.
