Do you have a secret formula for a granite polishing powder?

Estimated Reading Time: < 1 Minute

I don’t know if I’d call it a secret formula but the following granite polish formula should prove effective on most granite.

To one pound of tin oxide powder add 5 teaspoons of black oxide powder, 4 teaspoons of sulfur dioxide and 3 teaspoons of powdered lead.

CAUTION Lead powder is difficult to find and is hazardous to the environment. In place of lead you may want to use a lead and felt wheel. Start working the lead wheel wet and continue until dry.
