Iron Oxide, Spanish Red


(Red, Fe2O3),  - The varieties of irons mined- black, red, yellow - each give slightly different results. For consistent glaze effects it is best to stick with one source of iron. As a general rule, iron used in small amounts (under 1 0%) will produce browns, buff & rich reds in glazes. In larger quantities, may act as a flux. Synthetic irons are processed to meet specific standards & are more reliable. CAS#1309-32-1
