This porcelain grade media is an extremely hard media specially designed for high lustre polishing and burnishing of all metals.   This special "Rock Tumbler" mix is recommended for use as a filler media when using either Vibratory or Rotary Tumblers.

This mix contains approximately equal parts of the following shapes:  6mm balls (spheres), 6x6mm triangles, small 3x8mm cylinders and large 12x25mm cylinders.
Run these for a short period before using to "break in".
NOTE ON SHIPPING:  Limit of 4kg or less on Courier delivery (for satchel delivery).  Buy 5kg or more for price discount - select eParcel delivery at the checkout.

Plastic pellets are traditionally used as filler media for tumbling - they are cheap but do have a couple of disadvantages.  They need to be separated for each batch as grit carries through into subsequent stages and with their much lighter weight and density, do not work well in Vibratory Tumblers. 
Porcelain shapes have a similar density to rocks so work well in Vibratory Tumblers as a filler rather than moving unevenly through the load.  Porcelain shapes can be used right through the tumbling process and just topped up as you lose volume - a lot more convenient.
If you have insufficient rocks to run a full batch, just make up the load with our special Porcelain Tumbler Mix.
For more information on how to use these in tumbling, please see this informative article by Steve Hart:  "Best New Tumbling Product in Past 30 Years".
