Pumice is a natural mineral - volcanic ash formed by the solidification of lava that is permeated with gas bubbles. Pumice powder is used chiefly as an abrasive and is among the softest of all media. Use pumice powder for less aggressive operations where the protection of the surface is of supreme importance. Pumice is the best media choice for tumbling plastics.
FFF, 01/2 and 3 grades are most popular and are standard stock items.
