1) Silicon carbide grit is very hard. It is much harder than the rocks that most people tumble. On the Mohs Hardness scale silicon carbide has a hardness of 9 to 9.5 while commonly-tumbled 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
