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.

The first cab below is with Holy Cow/vinegar.

Quite a difference !

OK what is vinegar/Holy cow mix?

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.

Just ordered some on Ebay.  Here's the directions and prices.  Imagine you substitute vinegar for the water. 
Never even heard of it before this link, but it's worth a try.

Mix a few tablespoons of Holy Cow Polish with a small amount of water
to make a thin pancake like paste, keep
this mixture in an airtight container that has NO metal parts or
metal lid (metal will oxidize and cause
contaminates) I use a spray bottle for my shop. This mixture is
then applied to a dampened leather pad,
cotton buff, tin-lead, lead, tin or zinc lap, polypads, plastic
lap, resin pad, old ultra laps, ceramic lap,
phenolic lap, felt wheel or lap, wood spool polisher, computer CDs
or whatever you are using to polish
with now, with a small brush that has no metal parts and then rub
it in with your clean fingers. You can
replace different grit laps depending on the type stone your
working with. Keep a container of water
handy to cool and clean the stone as the more you polish the
better the shine gets and when the shine
doesn't get any better you've finished.
my price for Holy Cow polish is $13.00 per ounce
for one to six ounces plus shipping of $3.00 (EXAMPLE: Most orders for
small amounts usually are for two ounces $26.00 plus shipping $3.00 total
$29.00)...larger bulk orders of one half pound ($93.00), one pound ($170.00)
and five pounds ($685.00) plus shipping and insurance... if you would like
to have your HCP insured please add $1.75 for the first $50.00, $2.75 for up to
$100.00 and $1.00 more per $100.00 value after that...I accept PayPal, MO or
checks but NO C.O.D.'s...if you wish to pay by credit card I take credit cards
by PayPal only and before you pay please email me for payment instructions and an
invoice...
send payment to:

I had the pleasure of meeting Bill Myers last month.  He was the developer of "Myers Rapid Polish".  He sold the polish business to Val Carver at MLS but still cuts and sells cabs.  He polishes everything with his polish in a GyRoc 10 lb. vibe tumbler.  Everything had a mirror finish including the wonderstone on his table.  The now known as Rapid Polish #61 from MLS is considerably less expensive and is a .3 micron aluminum oxide.

I did a quick search for the Rapid Polish #61 .. Found that Stone Age carries it.

Not clear yet if it is just for tumblers or if it can be used on various polishing pads like leather ?

Thanks John..

Yes, definitely works on buffs.  They market a 3 micron aluminum oxide for rotary tumblers called TXP.  The Rapid Polish is .3 so same micron as Linde A.  I think MLS price s $14.50 per lb.  Works great on soft stones and hard stones on buffing wheels and vibe tumblers.  MLS is Minnesota Lapidary Supply in case anyone doesn't know.
