Abstract: It is pointed out that no completely adequate published accounts of the so-called “tinning test”, which is used as an aid to the identification of cassiterite, are known to the writer. All of them lack important details and many contain statements that are wrong.
What is believed to be a correct comprehensive account of the test under review is given, and certain other related qualitative and semi-quantitative tests for tin occurring as cassiterite are described.
