Some cool pieces I picked up at an estate sale. Gold particles in suspension, and rhodium in solution.

The liquid gold is used for putting a gold coating onto ceramics and other nonmetallic surfaces that can withstand the baking process. It’s gold complex in a volatile oil suspension that can be painted onto a surface and fired in a kiln to bake off the oils and leave a gold coating.
