Raspite is a mineral, a lead tungstate; with the formula PbWO4. It forms yellow to yellowish brown monoclinic crystals.[http://rruff.geo.arizona.edu/doclib/hom/raspite.pdf Handbook of Mineralogy] It is the low temperature monoclinic dimorph of the tetragonal stolzite.[http://www.mindat.org/min-3368.html Mindat entry]

It was discovered in 1897 at Broken Hill, New South Wales, Australia, it was named for Charles Rasp (1846–1907), German-Australian prospector, discoverer of the Broken Hill ore deposit.{{citation
