Heated on charcoal in the oxidizing flame, a slight coating of As2O3 is formed, and by addition of borax or sodium carbonate and continued heating a globule of metallic silver is obtained. In the open tube SO3 is given off and a volatile sublimate of As2O3 is formed. In the closed tube the mineral fuses, yields a yellow sublimate of arsenic sulphide and above the latter a very slight one of sulphur. The powder is readily oxidized and dissolved by nitric acid, the solution yields with HCl an abundant precipitate of silver chloride and on addition of ammonia in excess the blue color characteristic of copper is obtained, while a slight precipitate of ferric hydroxide is formed.","Yale University, New Haven, Connecticut, USA, 3.4270, 3.4292, 3.4293.\r\nThe Natural History Museum, London, England, 84843.","Pearceite-Polybasite series.\r\n\r\nOriginally pearceite was thought to be an arsenic analogue of polybasite. \r\n\"Arsenpolybasite\" was, however, found to represent two different polytypes of pearceite, pearceite-T2ac and pearceite-M2a2b2c.\r\n\r\nPearceite form...","Named in honor of Dr. Richard Pearce (June 29, 1837 Barripper, Cornwall - May 18, 1927 London), chemist and metallurgist.
