Pressed crucibles.
These crucibles are composed of Stourbridge clay and other pure materials, and are manufactured by pressure in moulds, whereby equality in size, thickness, and solidity are insured. They are made in sizes holding from 15 to 400 lbs. weight; will bear the fusion of copper and other metals, high degrees of heat, and sudden changes of temperature, and can be used for several consecutive days. They are now in regular use in the principal foundries in the north of England, and other parts of the country.
