Fire assay procedures use a combination of intense heat (1900 °F) that is produced by a furnace, dry reagents called fluxes, and bone ash containers called crucibles and cupels. One uses this combination to fuse the fluxing agents and to isolate the precious metals. The ability to fire assay a substance relies on a number of facts.

Ethanol is used to make alcohol, the beverage – and while ethanol is a type of alcohol, ethanol and alcohol are not the same. Ethanol is the intoxicating ingredient in alcohol. You should not drink pure ethanol – it can cause blindness and even death – and to discourage people from doing this, a bitter flavouring is added which makes ethanol unfit for human consumption.
