Cupellation is a term that typically refers to a type of assay testing method that is used to determine the purity of certain metals, such as gold or silver. However, there are other terms that can be used to describe similar processes, depending on the context and the specific metal being tested. For example, fire assay and scorification are both terms that can be used to describe similar processes to cupellation, but they may be used for different metals or in different industries. Other related terms might include oxidation-reduction testing, flux fusion, or smelting, all of which involve heating and melting metals to determine their composition.
