Abstract
A marking powder is disclosed for marking metallic bodies, in particular hot metallic bodies, which may be steel or other ferrous metal. Zinc is present in the marking powder in an amount 20 to 70% by weight, and it found that this results in improved legibility, which lasts for longer. The powder may be prepared by adding zinc powder to a known aluminum-based marking powder in an appropriate ratio. Coarse zinc powder was found to be better.
