QuoteTypists operated Mergenthaler Linotype machines with a keyboard as the automated machine selected character molds, imprinted letters onto paper and returned the molds to their storage area. This process involved the pouring of molten metal. Because the machine contained metal parts and generated a great deal of heat, effectively insulating the Linotype was an important concern for the machine's manufacturer.Linotype technicians typically packed a paste made of ground asbestos and water between the metal parts of Mergenthaler Linotypes. The wet asbestos coated the elevator jaws and crucible heaters, and also filled empty spaces between other mechanical parts. When Linotype parts were removed or replaced, new asbestos was sometimes poured into the empty spaces to freshen the insulation.
