Description
A yellow pigment composed of Iron chromate. Iron chromate is precipitated from a solution of a chromate salt, such as Potassium dichromate by the addition of Ferric chloride. The pure pigment is bright yellow, but some residual impurities, such as iron oxide, may result in a dull orange pigment color. Siderin yellow is compatible with all paint binders. It has also been used as a brown ceramic glaze and as a colorant in glass and enamel.
