"Mixed melting point determination" is a term used in chemistry. Organic substances have a fixed temperature at which they liquify. If a chemist wants to determine the nature of an unknown substance, he can determine it by these means. If the unknown substance does not melt at the usual temperature, it can be said to be impure. If the chemist has two unknown substances and wants to determine what they are, he may mix equal parts of each and start the liquification process. If the combination melts at the usual temperature, the chemist can say that both are the same. If the chemist wants to determine the nature of an unknown substance, he may mix a fixed amount of a known substance with a fixed amount of an unknown substance, it can be estimated, what the unknown substance is.
