These paints do not contain lead. Analytically detectable lead residues come from raw material impurities and from deposits during production. A few of the paints in this series (although not in this set) contain cadmium (Cd).
The colors are generally mixable with each other. However, do not mix the precious metal containing colors (product codes that begin with “BP”) with the remaining colors, although they can be mixed with each other, or with white or blue.
Colors can be applied by brush, airbrush (spraying) or by screen printing. Layer thickness should not exceed 0.02-0.03 mm.
