Can you be more specific on how you burnished them? I have heard of so many differing ways. Some do it wet, some do it dry. If wet how thick was the borax "slurry"? I am very impressed with the "shine" that they have for just coming out of such a course grit! Very interesting, thanks for sharring! Bill

I don't wash them after coarse but I do wash them after each step after that, generally overnight. After polish I do let them run for a good 24 hours. After being thoroughly rinse, I put everything right back in the barrel with hot water and about a tablespoon of borax and just let them wash. The idea is to remove any residue left on the rocks by the process.
I'm not even sure how washing the rocks in borax came to be called burnishing. Running them through the various stages to bring them to a shine is "burnishing" the rocks.
bur·nish Pronunciation Key (bûrnsh) tr.v. bur·nished, bur·nish·ing, bur·nish·es
1. To make smooth or glossy by or as if by rubbing; polish. 2. To rub with a tool that serves especially to smooth or polish. n. A smooth glossy finish or appearance; luster.

Hi Cher, What about the rubbing process of each stone on another with the sand particles in between helping to smooth ? just a Idea (or a crazy notion) ;D Jack Yorkshire UK

I don't know Jack, but I imagine that fits in to burnishing too, at least according to the dictionary entry I found, I guess in that case, the sand would be the tool. I was really hoping someone could provide me with the info as I am seriously wondering why it's called burnishing. I've never called it that myself, to me washing the rocks with soap/borax is washing just that ... washing them. I'm sorry if my post came off sounding like a poo, I didn't mean too. I am really curious about this, it's always confused me.

Cher, I always thought that burnishing refered to deburring metal parts. alot of metal parts are stamped out of sheets or rolls and have little burs left on them , they put them in a viberating machine with pellets or grit to shine them up and take the burs off --about the same as we do with rocks and stone so prob any step we do could be referred to as burnishing

I'll have to ask my son about that, he's the maintenance manager in a place that does just that. Mostly when he's talked about different things, he's referred to it as deburring cleaning the burrs off but they do run them through some kind of polishing stage also.
That's pretty much what I figured too, running them through the various stages/steps to make them smooth is burnishing the stones.
