| Reinsch's t. |
(for heavy metals, including arsenic, mercury, bismuth, antimony, and large amounts of selenium, tellurium, and sulfide): insert a strip of clean copper into the suspected acidified liquid or finely ground tissue, and boil; if one or more heavy metals are present, a coating will form on the copper strip.
