It commonly occurs as a colourless crystal or white powder and, unlike most other lead II salts , is soluble in water. Known since the Middle Ages by the name plumbum dulce , the production of lead II nitrate from either metallic lead or lead oxide in nitric acid was small-scale, for direct use in making other lead compounds. In the nineteenth century lead II nitrate began to be produced commercially in Europe and the United States. Historically, the main use was as a raw material in the production of pigments for lead paints , but such paints have been superseded by less toxic paints based on titanium dioxide. Other industrial uses included heat stabilization in nylon and polyesters , and in coatings of photothermographic paper. Since around the year , lead II nitrate has begun to be used in gold cyanidation. Lead II nitrate is toxic and must be handled with care to prevent inhalation, ingestion and skin contact.
