Kraisslite is a rare manganese magnesium iron zinc arsenite arsenate silicate mineral (Moore and Ito, 1978). The name honors collectors Alice (1905-1986) and Frederick Kraissl (1899-1986), major supporters of the Franklin Mineral Museum and the Franklin-Ogdensburg Mineral Society. Kraisslite here forms a foliated coverage on a fracture surface of calcite-willemite-franklinite ore. The kraisslite coverage consists of tiny scales and looks a bit like crushed velvet. Rare and type locality material!
