Essentially the wheel holds sandpaper and so you hold a rock slab on the spinning wheel and it sands down the rock (like a belt sander sands down wood). For a finer polish you just swap to a finer sandpaper until you get a glassy, beautiful polish on your slab.
While there are still a few small things the lab still needs (drying over, more glassware and chemicals etc.), the lab is really coming together. It is starting to look really beautiful and is extremely functional (it is a little messy, but that is because people are using it, yay)!
I am so excited for how well this has come together! This was a big time sink for me in the first few years, but I think it has really paid off.
If you're in Austin and need to do some rock-related science, I have just the spot!
