In some German factories white lead, after it is ground and washed, is mixed with a cementing material, such as isinglass, gum-water, or similar substances. It is then made into tablets, when it is termed " kremserweiss ; " or it is formed into little pyramidal shapes, which are wrapped in blue paper and called Venetian white lead. In some German and Austrian factories all perfectly pure white lead is termed " kremserweiss," and that adulterated with barytes, or other substances, is called " Venetian " white lead ; a still greater degree of debasement is indicated by the terms "Hamburg," or "Dutch" white lead.
