Rublev Colours Pigment Ardennes Burnt Sienna - 100 g

Iron oxide earth pigments, often called, are an important group of inorganic pigments derived from minerals. Iron oxide pigments are yellow, red, and brown, but artists know them as ochre, sienna, red oxide, and umber. Unlike manufactured pigments, the colour of iron oxide earth pigments varies with the composition of the particular segment of earth from which they come. The colour of sienna earth pigments is derived from three constituents: the principal colouring ingredient, a secondary colouring ingredient, and a base. The combination of these ingredients produces the particular color of the earth. The innumerable forms and variations in which these ingredients can combine result in a wide range of yellows, reds, and browns.

Warning: Burnt Sienna is considered non-toxic, but care should always be exercised when handling the dry powder pigment to avoid inhaling the dust.
