Silver Nitrate, Toughened. Lunar caustic fused silver nitrate molded silver nitrate. Consists of about 97-911% silver nitrate, remainder is silver chloride to toughen it. 

Silver nitrate forms colorless, rhombic crystals. It is dimorphic and changes to the hexagonal rhombohedral form at 159.8°C. It melts at 212°C to a yellowish Hquid which solidifies to a white, crystalline mass on cooling. An alchemical name, lunar caustic, is stiU appHed to this fused salt. In the presence of a trace of nitric acid, silver nitrate is stable to 350°C. It decomposes at 440°C to metallic silver, nitrogen, and nitrogen oxides. Solutions of silver nitrate are usually acidic, having a pH of 3.6—4.6. Silver nitrate is soluble in ethanol and acetone. 

Other articles written by Taddei focused on the study of the so-called stone of hell or lunar caustic, silver nitrate (AgNOs) in modem terminology. This compound was used in medicine and veterinary medicine to cauterize infected wounds. It came in several forms fused with other salts. The so-called form mitigated form contained a quarter to a third of potassium nitrate (KNO3), while the so-called hard contained 2-5 % lead chloride (PbCl2) or silver chloride (AgCl).
