	O	29.28							This is a reflected light micrograph of polished, carbon coated willemite crystals. The identifying etched label, which is a feature of our standards, is invaluable for navigating in an electron beam instrument. This standard offers a major quantity of zinc in a silicate matrix, as well as providing an excellent means of locating the electron beam through its bright green cathodoluminescence. It is named after King Willem I of the Netherlands. Locality: Franklin Furnace, NJ, USA
