Antimony is a lustrous gray metalloid primarily found in nature as the sulfide mineral stibnite (Sb₂S₃). Known since ancient times, antimony compounds were used in medicine and cosmetics, often referred to by the Arabic name *kohl*. Although metallic antimony was recognized, it was initially mistaken for lead. The earliest known description of the metal in the West was by Vannoccio Biringuccio in 1540. Industrial refining methods for antimony include roasting and reduction with carbon, or direct reduction of stibnite with iron.

Tellurium is a chemical element named after the Latin word *tellus*, meaning “Earth.” It was first mentioned in 1782 by F.-J.M. von Reichenstein and was later isolated and announced by H. Klaproth. The chemical symbol for tellurium is “Te.” It is located in Period 5, Group 16 of the periodic table, within the p-block. Its atomic number is 52, and its relative atomic mass is 127.60, with the number in brackets indicating the uncertainty.
