Here comes a stupid queston I am sure experienced tumblers know the answer to.
I was cleaning a batch of rocks this morning, and I suddenly thought: If grit can grind down and shape hard rocks in a matter of weeks, how come it doesn't eat away the inside of a rubber barrel at the same rate? I would think that soft rubber would not hold up to Silicon Carbide grit, but yet it does. Why is that?

well its got something to do w/ molecular structure which is something I certainly can't explain
suffice to say those sharpy little grits bounce around tumbling like rocks in a barrel
pf course, they think its fun butte I never asked one mohstly
hope your day is to!

It’s a great question! One way I think of it…. Scale it up. If you drive over a piece of quartz with your car, the tire will give way to the rock and then be resilient and bounce back. As long as it is kept cool rubber is extremely tough and resilient, and very difficult to separate the molecules.

Also a Mohs 6 hammer can shatter a Mohs 10 diamond How does that work??

Same deal w/the tires on your car. Yes, kind of, but I think that if I started rubbing rocks and grit on the side of my tire something bad would eventually happen :-) :-(
