- Argol — An archaic technical or unofficial industrial term historically used to denote crude wine tartar, a crystalline crust structurally composed of impure potassium bitartrate that deposits on barrel walls during wine fermentation or long-term storage. In the early chemical industry, argol was collected, refined, and utilized as a vital raw material for manufacturing cream of tartar or as a mordant in textile dyeing.
