Description

A synthetic green-blue pigment made by fixing barium manganate on a Barium sulfate base. Manganese blue was first discovered in 1907 but not patented until 1935. It is an inert pigment that can range in color from a clear azure blue to a bright emerald green (manganese green). Manganese blue accelerates the drying of oil paints but has poor tinting strength. It has been used most frequently for tinting cement.
