Abstract:
1. Glass flakes, which have been subjected to leaching-out in water, an acid or a caustic lye, which after the leaching-out, have a composition comprising 50-70% by weight of SiO 30-50% by weight of TiO 0-3% by weight of Na where the total amount is ≦100% by weight, based on the glass flake, and which before the leaching out, had a composition that comprised at least one crystalline phase, wherein the glass flakes have one of the following oxide coatings: glass flake+TiO glass flake+TiO glass flake+Fe glass flake+TiO glass flake+TiO glass flake+TiO glass flake+Fe glass flake+TiO glass flake+TiO glass flake+TiO glass flake+TiO glass flake+TiO glass flake+SnO glass flake+SiO glass flake+SiO glass flake+SiO glass flake+SiO glass flake+SiO glass flake+SiO glass flake+SiO glass flake+SiO glass flake+SiO glass flake+SiO glass flake+SiO glass flake+SiO glass flake+SiO
