In another thread a German guy used little carbide bricks and then tempered glass to hand grind and polish a rock. I mentioned that a few months ago that inspired me to try it with 2 tempered glass shelves from a fridge. Here are some pics... s1224.photobucket.com/user/clark241/library/

Copy and paste the IMG tag for each photo into your message. Done.

Thanks for sharing. How much work was it to get to a decent polish time-wise? Any details you'd like to share about the process would be welcome.

oh those have been in a rotary tumble. Im trying to flatten out the petrified wood, and it takes hours.
So when I get around to it, I turn on a movie and just let my arm grind it in a figure 8. I keep it just wet enough that I dont put much pressure and just let the rock 'glide' on the grit.

Well, I polish my rocks by hand also, but I use wet/dry sand paper-silicon carbide, on glass. Never tried grit...yet. It's just easier for me to get many different grit sizes. But I will give grit a try. Sounds good.

yeah after the first hour or so you can just turn your head and watch a movie while your arm goes about its business.

watching a movie and polishing by hand is too many things going on at one time. Also, I having better results with using grit this time.
