Thismixture is packed between the two carbon polescarrying the current, there being, however, acentral core of coke placed directly betweenthe carbon poles, providing thus a conductorfor the current and so overcoming the difficultyof starting up, and also keeping the internalresistance more uniform by breaking up the arcinto numerous small arcs. Carborundum is asilicide of carbon ; the formula is CSi. W 00D or METAL WorKcrs Without Steam Power shoulduse oar Foot and Hand Power Machinery.
