Lifting-tongs
A form of tongs with which to lift a crucible out of the furnace. They should always be strong, and of various sizes, so that each crucible has its own tongs which grips it closely all round. For large crucibles it is preferable to clasp them above and below with tongs that have double prongs, and an eye should be forged on the end of one leg. By this means a small crane may be employed for hoisting out the crucible when full of metal,--a readier and much safer method than struggling to withdraw it by hand. See CRUCIBLE.
