Anthracite

African Pegmatite produces milled Anthracite which is used to trim redox (reduction-oxidation) levels in the reaction when colouring glass. Anthractie is used with pigments such as chrome flour and manganese dioxide when producing green bottles. Anthracite/ is a safe measure and ensures that the colour is consistant. Anthracite is also used in the production of clear glass.
