Grits and Media

To obtain the smooth, rounded and polished appearance on any tumblestones is the grit and media used during the tumbling process. The constant rotation of contents in the barrel mixed with media or grit slowly chips and erodes the rough parts of rough rock and minerals away until you have a smooth pebble like stone. Further tumbling with polishing grit or media gives the contents, its completely smooth and shining appearance. In this section you will find a small range of grits and media to assist you, from the finest grit to the larger size steel media.
