Re: [ATM] Cerium Oxide
Geoff;
CeO comes from a variety of places, trace elements in it determine the
color of it. It seems most American sourced material is typically the
ruddy color, while here in my shop we use a French product Cerox 1663,
which is bone white in color.
The actual particle size and grading quality have more to do with its
efectiveness than color.
