Rock Tuler Grit and Silicon Carbide Grit Kits
1) Silicon carbide grit is very hard. It is much harder than the rocks that most people tule. On the Mohs Hardness scale silicon carbide has a hardness of 9 to 9.5 while commonly-tuled rocks such as jasper, agate, quartz and petrified wood have a Mohs Hardness of about 7. This means that silicon carbide grit can easily abrade the rocks that
