Bill, you suggested that workers were using Chromium oxide instead of Aluminum oxide for historical reasons. I asked you for documentation. If you have done no research, why talk about historic practices?

Chromium oxide occurs naturally, but it is very rare. It has been used for centuries as a pigment, and probably was historically too valuable as a pigment for use as an abrasive. Even when chromium oxide was synthesized in the 19th century, chrome was very expensive.

Aluminum oxide occurs naturally and is mined for abrasives. It was also synthesized in the 19th century and was marketed for India stones in the 1890s.
