Electric Heating
The commercial use of electric heating is one of the more recent electrical developments. For the most part, this also applies to the garment trade and its closely allied clothing industries. In the modernly equipped factories one finds electric flat irons, velvet steamers and coffee urns. In the printing trade, electrically heated linotype melting pots are being introduced successfully, while glue-pots and sealing-wax melters can be seen in binderies and banking institutions. Absence of fire risk accounts for the introduction of electric heating units of different kinds into the motion-picture film manufacturing industry, a rapidly growing province. The same element of safety where inflammable substances are employed has produced the electric japan oven and similar apparatus.
