Tumbling Media

Burnishing Compound

Great for both silver and gold. A high quality burnishing and lubricating compound. Use in the ratio of one heaping tablespoon to one gallon of water. Adjust if necessary. For bright, clean finishes, the burnishing compound must be used in the right proportion and any resulting sludge rinsed away before particles embed and dull the metal.

BRN005-- Burnishing compound 5 lb

Ceramic Angle (Angle cut triangle)

A 3/8" x 5/8" size ceramic media containing no abrasives. When tumbling rocks, use ceramic angles as a pre-filler to occupy space inside the tumbler and as a carrier to deliver grain abrasives to the work pieces. Adds weight to the load for increased tumbling action and separates work pieces to eliminate parts sticking together.

Corn Cob

A pithy material made from the hard woody ring of the corn cob. It is used as a very gentle finish and drying media in polishing and burnishing metals. Absorbs many times its weight. Readily removes oil, dirt and grease from tumbled parts.
