== Description ==
White, translucent crystals that are produced by the reaction of nitric acid on lead. Lead nitrate is a strong oxidizing material. It is used as a mordant in dyeing and printing calico and for staining mother-of-pearl. Lead nitrate is also used as a sensitizer in photography and is used in engraving and lithographic processes.

Lead paint

== Description ==
Any paint product containing a lead-based pigment. Lead pigments, such as lead white, red lead, and chrome yellow have been widely used in artists and household paints. However because of their toxicity, their usage dropped significantly. With the production of zinc oxide in 1834, many artists' paints switched to the use of the nontoxic white pigment. Regulation in the United States restricted the use of lead pigments in interior house paints in the 1950s and then prohibited its use in 1978.

Lead pencil

== Description ==
A soft drawing pencil. The first picture showing a lead pencil appears in a 1565 woodcut as an ornate wood tube holding a tapered lead piece. The early lead pencils contained soft metallic lead points encased in wood or bone shafts. The marks were easily erased from parchment with bread crumbs or a soft leather cloth. In the mid 19th century, graphite pencils became more popular. The shafts of graphite pencils are made from graphite mixed with clay. However, the earlier name of lead pencil transferred and, though incorrect, its use continued.

Lead tetroxide

== Description ==
A heavy, bright red powder that occurs naturally as the mineral minium. The mineral form, however, was rarely used. Instead lead tetroxide was prepared by slowly heating lead monoxide in a furnace with a constant flow of air. Excess heating will turn the pigment to an orange shade that is known as orange mineral. Lead tetroxide, also called red lead oxide, was one of the earliest synthetic pigments. It is no longer used as an artists color because is has poor light stability and poor working properties. Instead, red lead is used to color glass, enamels, and ceramic glazes. It is also used as a flux in porcelain painting, an anticorrosive paint for iron and steel, and as a component in lead batteries. Because of its toxicity, the use of red lead is declining.
