=== Dross ===
Regeneration-metal{{clarify|date=June 2023}} was melted into the [[crucible]] to replace lost tin and antimony through the [[dross]].{{cn|date=June 2023}}

Every time type metal is remelted, tin and antimony [[Oxidation|oxidise]]. These oxides form on the surface of the crucible and must be removed. After stirring the molten metal, grey powder forms on the surface, the dross, needing to be skimmed. Dross contains recoverable amounts of tin and antimony.

Dross must be processed at specialized companies, in order to extract the pure metals in conditions that would prevent environmental [[pollution]] and remain economically feasible.
