Yellow iron oxide is a synthetic material of very fine particle size (but not as fine as black or red). Actual yellow iron oxides are around 85% Fe 2 O 3 and about 12% LOI with some impurities (e.g. SiO 2, CaO ). Theoretically, any form of iron could be used to source Fe in the fired ceramic product (of course they lose different amounts of
