Weighing-scales
A more active and intelligent practice in foundry operations has made weighing-scales a prime necessity on the charging-platform. Without accuracy in charging-material it is useless to expect uniformity of mixture, and the result is invariably a marked failure wherever the quantities of materials introduced are left to the furnaceman's judgment; the latter word being, in this instance, a misnomer, as the fact of being without scales evidences a lack of sound judgment.
