This melting-point apparatus for use with a microscope was developed by the Austrian pharmacognosist Ludwig Kofler (30 November 1891 Dornbirn - 23 August 1951 Innsbruck) and his wife mineralogist Adelheid Kofler. In 1936, the Koflers and Mayrhofer published their "Mikroskopische Methoden in der Mikrochemie" [Kofler, L., A.
Other metallurgical furnaces have special design features or uses. One function is heating material short of melting, in order to perform heat treatment or hot working. Basic furnaces used this way include: A forge is the traditional metalsmith's hearth for heating metal while forging
A cupola or cupola furnace is a melting device used in foundries that can be used to melt cast iron, Ni-resist iron and some bronzes. The cupola can be made almost any practical size. The size of a cupola is expressed in diameters and can range from 1.5 to 13 feet (0.5 to 4.0 m). [1]

While the outward designs of apparatuses can vary greatly, most apparatuses use a sample loaded into a sealed capillary tube (melting-point tube), which is then placed in the apparatus. The sample is then heated, either by a heating block or an oil bath, and as the temperature increases, the sample is observed to determine when the phase change ...

Ingots and off-cuts of aluminium are melted in a natural gas-powered melting oven operating at 850 °C (1,600 °F), until liquid. Slag in the form of aluminium oxide is mechanically removed from the surface, and the rest of the liquid metal is pumped through heated pipes to an enclosed warming oven operating at 750–850 °C (1,400–1,600 °F ...
When selecting a melting tank, it is important that the application is known. For example, if melting large amounts of substances (or at least more than 10 or so gallons) is the goal, then water-jacket melting is the proper choice. If the substance needs to be heated to over 212 °F, then a direct-heat melter would be necessary.
