Ok.. Gave it a whirl tonight.

Ran both cabs up to 14,000 ths. Then hit one with the vinegar/Holy Cow mix, and the shield with Tin Oxide.

Quite a difference !

I'm wondering the same thing.  Not like I have the equipment to polish with but it would be interesting to know what it is for the future.

Gorgeous Cabs George too.   yes

Great results! I have a friend that uses vinegar when polishing ryolites. He gets good a pretty good polish on them. I am glad that you posted the pics too, nice examples. I guess you can do almost the same thing on chinese cherry creek jasper . Cherry creek jasper takes a better polish if you use vinegar and tin oxide. Thanks, for the tips! Eric.

I googled Holy cow and find it was developed, named and is distributed by a man named Guy Clark.  http://www.gemcutters.org/LDA/Archive/html%20files/LD235.htm  Read message 10 and 11.  I have no idea how old these posts are but it does list Guy's phone number.  On another forum it states his number has been disconnected.  I hope he hasn't been. That was in 2004,

I think Holy Cow is an aluminum oxide blend.

The  Holy Cow/Vinegar looks really good. How dense is the Wonderstone? The local stuff grades from coarse, really earthy siltstone like to compact, smooth jasper like and about every grade in between. The coarse is impossible to polish and the smooth takes a great polish. I don't think the mineral composition changes much. More of a difference in density and grain size. My Keep Cool Rhyolite is about in the middle to a little denser........Bob

Vinegar is an acid.  An old timer told me years ago he dampened his buffs with diluted oxalic acid rather than water.  Does the acid affect the stone or the polish?  Any "Mr. Wizards" out there?  Since I remember Mr. Wizard from TV I guess I'm an old timer too.

I am far from a wizard but I would guess the oxalic acid affets the oxidized polishing compound. Probably the same with vinegar to a lesser extent. The "old timer" that gave me this information also said to use very little vinegar. Just enough to get the polish damp. BTW he is now 94 and still running his rock shop!!!    Bob

There is quite a difference on the shine.  The only holy cow I have seen on sale is on ebay.  Once I get set up again I will just have to buy some and try it out.  Thanks George.

The vinegar/Holy Cow mix.. It is suppose to be mixed just like an oxide polish and water. Sorta creamy..

Jeff of Elegant Cabs sent me a little. He was selling it at 16.00 an ounce.

I don't know what exactly dictates when to try Holy Cow. Here is a pretty good thread where a few members shared some Holy Cow moments.

Bob.. I think this was a little better than average Wonderstone. I have only purchased it once when I first started cabbing. These two slabs seem more dense than what I remember.
