	C	99.8							This is a reflected light micrograph of polished, carbon coated graphite. The identifying etched label, which is a feature of our standards, is invaluable for navigating in an electron beam instrument. This form of carbon is extremely soft and therefore polishes very poorly. Source: 1.5mm rod RW1447, Ringsdorff-werke GmbH, Bonn, Germany
