Blanc fixe

For heavy opaque colors, lowers oil absorption. Synthetic barium sulfate is the white pigment with the best reflectance for visible light (the reflectance of barite reaches nearly 100% without or almost without binder) and is therefore also used as a white standard in metrology. Barium sulfate is a very good inert blending agent for very strong pigments such as milori blue or chrome oxide green or a carrier substrate for colored paints. The heavy, pure white powder covers very little in aqueous binders and moderately in oil. It is also suitable for acrylics, ceramics, tempera and water glass.
