We supply two types of metallic powders, these are Bronze Powders and Pearl Lustre Pigment Powders (Mica Powder). The bronze powders are very fine and come in a range of metallic colours. Despite their name they are not made of bronze. The powders are made of varying mixtures of copper and zinc. For best results use over oil based size or mix with bronze medium. All can be mixed into clear wax to make gilt wax/cream. They can also be mixed with water, oil, spirit or varnish and are for interior use only. The Pearl Lustre Pigments are made from mica flakes, finely coated with titanium and/or iron oxides. The thickness and combination of coatings produces refraction of light to give an appearance similar to oil film on water. They can be mixed with any medium, are non-toxic and totally lightfast. They are impervious to acids, alkalis, water and temperatures up to 800oC and are best used over dark base coat colours. They give a wide range of effects from soft satin to sparkling brilliance over other colours. The brightest shades can be obtained by mixing a tiny amount of black pigment (1:100) with the pearl lustre pigment. Duller effects are obtained when they are mixed with opaque colours or matt mediums.
