Very fine pigment powder containing real metal. Mix the pigment powder into the mixed resin or use it for mixed-media or scrapbooking projects to give them a metallic effect. Can be mixed into both water-based and solvent-based varnishes too. Solvent-based mixture will dry rapidly. 

In the photo, the mixture I used on the frame is:

1 part Silver metal pigment powder to 3 parts water-based Gloss Clear Coat (Hewbury Paint)
