The rosin powder referred to by Steve, above, is a product of pine tree sap, or rosin. In the South it is referred to as pine tree fat. It ignites easily and burns very hot when impregnated in the pine wood. When I used to cast a lot of lead bullets I fluxed the molten lead with small pieces of the rosin.

It is also used by baseball pitchers to get a good grip on the baseball. And, I have been told, by gymnasts on the rings and the balance beam.

May God bless America and those who defend her.
