A simple method is proposed for copper, lead and manganese determination in deciduous teeth by graphite furnace atomic absorption spectrometry (GFAAS) using slurry sampling introduction and cryogenic sample preparation. Teeth samples were ground in a cryogenic mill in two steps: pre-cooling (5 min) and cryogenic grinding (2 min) in liquid nitrogen.

Manganese steel's unique wear-resistant properties also make it very difficult to machine, at best. In the early days of manganese steel production, it was thought to be unmachineable and grinding was used to shape the parts. Now with modern cutting tools, it is possible to turn, bore, and mill manganese steels.
