Abstract
A method for producing pigment flakes in the shape of thin plates. A chamber is provided which is placed under vacuum and a gas, which is capable of forming a plasma upon its exposure to a plasma generating device, was fed to the interior of the chamber device. The plasma is created within the chamber which forms a film upon a surface within the chamber. The film is converted to flakes which are then removed from the interior of the chamber.
