DANIEL SMITH Watercolors are formulated to meet and exceed the highest industry standards for the manufacture of artist’s paints, and every batch made is tested and analyzed for its performance qualities. PrimaTek Watercolors are made from minerals, often semi precious minerals, that have been ground into pigments, mixed with gum arabic (the binder) and milled into PrimaTek Watercolors. The first was Lapis Lazuli Genuine in 1998, since then, many more have been added such as Amethyst Genuine, Piemontite Genuine and Serpentine Genuine. Most of these colors have wonderful granulating effects that some artists have called “magical”.
