ABSTRACT:
The melting point of a powdery or particulate material is determined by allowing a sample of the material to contact a heated surface. If the material does not melt it is removed from the surface and the temperature of the surface is increased. The process is repeated until the material is observed to melt on the surface, the temperature of the surface at that time being observed in order to determine the melting point in question.
