When you go to sell, make sure to take good,clear photos of each and give measurements (length, width and thickness).

I believe there is an old, patented process that can create petrified wood with sodium silicate and acid. To answer your question though, I've cleaned and polished metal objects in a vibratory. No cheese.
"Is a few million years too long to wait? Scientists have developed ways to petrify wood in the laboratory in as little as four or five days. One such process was developed at Pacific Northwest National Laboratory about a decade ago. It involves soaking a section of wood in hydrochloric acid for two days and then in either a silica or titanium solution for another two days. After air-drying, the wood is placed in an argon gas filled furnace and slowly heated to 1400° Celsius over a period of two hours. It is then left to cool to room temperature in the argon gas. What results is a block of ceramic silicon carbide or titanium carbide. Probably not as beautiful and interesting to look at as the one that took millions of years to form, but cool nonetheless."

James, what about sodium silicate? I've never played with it but have been told I can make a sort of coprolite by taking an old dry cow turd and treating it with this stuff. Any truth to it? Now Googling sodium silicate… Also known as water glass. Has a lot of uses and very easy to make as well. Molten sodium hydroxide and glass. There is also potassium silicate made using potassium hydroxide instead.

If you want to actually try to polish the cheese, dru it out thoroughly then soak in oxalic acid so the oxalic acid will bind with the calcium forming an insoluble an somewhat calcium oxalate. I would also add some oxalic acid to the water tray of the cabbing machine so that any newly exposed calcium that did not react before will form calcium oxalate. Not sure if it will be hard enough, but if you want to experiment then that is what I would recommend. As for cremation ashes and stones, they have been doing several variations of this for a while including ceramic stones made with cremation ashes. James, what about sodium silicate? I've never played with it but have been told I can make a sort of coprolite by taking an old dry cow turd and treating it with this stuff. Any truth to it? I use sodium silicate a lot. It can work with calcium as well forming a calcium silicate, but the problem I see is that sodium silicate is very alkaline, and it polymerizes very quickly with acids. Cheese is acidic, which would likely polymerize the sodium silicate at the surface of the cheese preventing it from really penetrating deeply in to the cheese.

Hard to say for sure being so rough, but from what I can see it appears to be pink chalcedony (cryptocrystalline to microcrystalline quartz).
