Coppery. Metallic looking mica powder. Pour onto epoxy clay after shaping, but while still fresh and adhesive. The powder adheres to the clay for a metallic look. (Not enamel - so no respirator needed.) Jar contains a generous gram - which is about a teaspoon full. Jar has a little insert with holes for shaking out the powder. The holes are covered with a plastic sticker to prevent leaks (it's clear and practically invisible) - you have to remove the sticker for the powder to flow! You can also pull out the insert if you want to just dump the powder out - but do this very carefully - as the powder has a tendency to jump out and get on everything. Don't do this over your keyboard! Non-toxic.
Also works with polymer clay, resin.
