✦ Synopsis
When tlie tenllwraturc of a substance is plotted as a function of the amourlt of heat supplied to it, the resulting curve is indicatctl as n tcmpcraturc-heat content curve. Such ;L curve comprising the melting range of the substance is called the melting curve. Almost every impurit> soluble in the melt will influence the shape of the melting curve, and, in fact, the melting curve offers a very gcncral sensitive and non-dcstructivc criterion for purity. Howcvcr, \vlicn attempts arc mndc to stntc the data on purity in csnct figures, clif'ticultics arc cncountcrcd.
