The Alberta rocks are starting to come through stage one of rock tumbling. The smaller rocks turned the tumbler water red. I thought that was different.
I reloaded the ones that were not ready and another load of large Ontario rocks.
The Thumblers tumbler is nice and quiet by the way. The toy one is quite noisy. The rocks make noise and the motor. It’s still okay behind a closed door but it’s notable that there is a considerable difference between the two machines.
