Just curious... I had seen a video where someone rubbed jojoba oil over their rocks, letting them dry overnight then putting them in a polishing cycle. Has anyone else tried this? I’m just curious if rubbing the rocks down in oil actual helps with the polishing cycle at all or if it doesn’t impact the polish one bit.
If no one else has tried it I may do it myself to see how it affects the polish if it would at all. From what I saw in the results of the video it didn’t make a change.

Tumbling rocks will remove some of the surface so I don't see how it could make a change. Seems you would get the same results if you added oil to the water.

Some rocks will not polish well in a tumbler. This may be due to how soft they are or the texture of the rock. A buffing compound like ZAM , a wax or oil can be applied as the last step if you want them to look shiny.

I have heard of oiling such rocks as Jade. The only other benefits I could possibly think of would be to penetrate cracks and crevices to possibly seal them off to keep water and polish out of them, no idea if this would offer any advantage.

Thank you stefan and Wooferhound I can’t see how it would help the polish but like I said I may try it myself and see if it does anything overly helpful, I can’t find much on it helping but who knows! May be a new recipe that hasn’t become mainstream yet or it may really just be a helper with sealing cracks but I would assume the oil would come out while going through the polishing stage... irlcjrohr I have heard of oiling or waxing the rocks after they come out of a polish cycle but not before

Assuming the oil was a hardening oil, such as boiled linseed oil, the oil wouldn't seep out if it were given enough time to harden.

what kind of rocks did they oil. Some rocks the oil would penetrate others not so much.

rmf I’m pretty sure they were river rocks they had found, not agate but possibly some type of Jasper I would assume?

irlcjrohr I’ll see if I can find a link to it somehow, it was a video sent to me, I think from tiktok but I’ll try to find it and see if I can save the video if it doesn’t have a link

In the past, I have put polished rock back into a stage 4 polish, that I had previously "oiled" with automotive Armour All or Mag wheel polish (when I wasn't happy with the original results). I don't think the oil stayed long on the rocks or helped in any way. What mattered was longer time in polish and then burnish.

I would worry about the oil (or any hydrocarbon) attacking the rubber barrel.

The only other benefits I could possibly think of would be to penetrate cracks and crevices to possibly seal them off to keep water and polish out of them, no idea if this would offer any advantage. The oiling of jade is usually done for natural pieces, so that they shine like a polished rock, but maintain their natural shape and texture. This practice is usually for beach pebbles that are drilled and strung onto either a hemp or leather thong as natural pendants, or for suiseki stones i don’t really hear about it in conjunction with polishing, so I would second the guess that the rocks used don’t polish well. And why jojoba oil? While relatively shelf-stable, it would eventually go rancid. The practices above use mineral oil, and it needs to be reapplied regularly as it absorbs into the stone
