Rublev Colours Pigment Mars Red (Blue Shade) - 100g

The first Mars pigments were manufactured by precipitating iron(II) sulfate (also called ‘gree‘ vitriol’ or ’mart‘al vitriol’) mi’ed with alum with an alkali, such as lime, caustic soda, potash, etc. The residue was then washed carefully to remove any remaining salts. Other salts of iron (iron chloride, iron nitrate, or iron acetate) were also used to manufacture the pigment. The precipitation of iron salts and alkali produced a yellow-brown pigment. Mars yellow was the starting material for other Mars colours.

Warning: Mars red is not considered toxic; however, care should be taken when handling the dry powder pigment to avoid inhaling the dust.
