All That Glitters Is Not Gold

SpecialChem / Nick Morante – Mar 22, 2007

It could be blue, green, red or even iridescent. I promised a friend I would write a short article about some special effect pigments. To be more specific, metallic pigments and glitters. First of all let me say that the metallic pearl pigments are considered color additives by the Food and Drug Administration while glitter pearls are not. Several companies manufacture these pigments but the best I've seen come out of Europe. Let's talk about the metallic pigments first. Metallic pigments are exactly what they say they are. They are finely ground metal flakes. They can be either aluminum, copper or bronze. The aluminum is obviously a very bright opaque silver. Depending on the oxidation the others can vary in color from bright gold to bronze. They are marketed in this country under the name Visionaire. You've probably heard of them. They are from a company called GeoTech in the Netherlands which markets them in the United States through Eckart. The aluminum pearls are sold under the name of Silver Sea and Bright Silver Sea. Silver Sea has a particle size of 20 microns.
