47.502 = Zam Polishing Compound 1/4lb

Zam is formulated especially for silver and turquoise jewelry. It will not scratch soft stones such as turquoise making it time-saving to use, since stones do not have to be removed before buffing a new piece.

Zam leaves a high luster without residue. It has fast clean-up, does not cling to or penetrate the surface of stones. It's so versatile, that many goldsmiths prefer ZAM to rouge as a final finish.
For use with high-speed polishing and buffing wheels.

Sold in a 1/4lb peel-away tube.

This helps prevent the bar form breaking apart and cuts down on the mess associated with handling. Just tear away the cardboard to reveal more compound as needed.
