Anyone else use Titanium Dioxide for polish? With the price of the rare earth polishes these days, this seems to be among the cheaper polishing compounds - even though as a rare earth it has also has gone up in price.

I spoke with a guy two days ago that uses it. He said it works great. I found some in my dad's stuff and it worked well on Montana agate in a rotary. I tried to google a source for bulk quantities and only found Chinese companies and info about make up and paint pigments. Also some hints of possibly being carcinogenic if powder is breathed.

I would also think that anyone that leaves pits and fractures all the way to polish stage would have lots of white spots to mar their work.

Titanium dioxide is the standard polish packaged with Thumler’s tumblers.

Titanium dioxides And there is Bulk quantity in all grits. This has been my number one supplier, and cheapest. And i can count on them to get order out fast. You well need a tax number to do business with them though. Jack in Oregon

You can buy TiO2 in bulk from folks that cater to the hobby soap makers. www.soapgoods.com/Titanium-Dioxide-p-670.html?gclid=CJL_zLLrv6kCFRx3gwodvWDCgwFrom these folks $27.44 will only get you 4 pounds. If you have any local paint manufacturers they may sell you some. The first TiO2 I tried was given to m by a chemist for the local paint factory. It did a great job, but I didn't like working with it. When cerium becam so expensive I went back to it. I've been using it for a couple of years. It works quite well. It's no worse than any other good polish at sticking in the pits and cracks - excepts that is shows up more since it is so white. I don't like working with it as it stains everying white - shoes, pants, hands, concrete pad. In a high humidity enviornment iit also cakes and sticks to everying. In case anyone is interested it takes about 2 and a half 5 gallon buckets to hold 50 pounds of dry TiO2 powder. Yes you shouldn't breath in the powder, or any other polish or rock powder for that matter. TiO2 does tend to float in the air more than other polishes.

Jack, that is Val's retail catalog. I do have his dealer price list but didn't check his bulk price. Thanks Steve. The guy I spoke to has a "back East" source for $400 for 2000 lbs. I got excited at that price. It is used in paint, sunscreen, and many other things where white pigment is used. I'm just guessing without "lapidary" in the name it would be less expensive.

If $400 a ton is legit grab it fast. This strikes me as either a very old out of date price or a "fell off the truck" price. www.icis.com/v2/chemicals/9076545/titanium-dioxide/pricing.htmlI've tried to find non-lapidary sources for tin oxide, looking for better pricing. So far no success. Although I restrict my use of tin oxide to vibes and polish pads so a little bit goes a long way.

Consider the filler that is use in Paint grade Titanium Dioxide. i`v dealt with paint supplier, since the late 60s. the biggest complaint they had. was that they only use up to 1.5% titanium in each batch. and that's the high-grade line of coatings.... And they were allotted yearly amounts. Porcelain, iron oxides, is the main filler in paints. The Latex line. Oil base a lot more oxides used. Old days cadmium, leads ( white / Red lead. ) Death in a can. I should`v pass on three bridges ago. Way to tell your paint has titanium in it, Scratch it with a coin - black stripe aluminum oxides is a good polish for soft material. Jack

I made latex architectural paint for a couple years and we used a lot more than 1.5% titanium in our low grade paints.

That was the first polish I bought, but switched to cerium when cerium was cheaper. Glad I still have some TiO2 left.
And yes, it is hard to get out of pits and cracks. A dry cleaning spot gun comes in handy.

Read a toothpaste label lately?
TiO2*. Also contains hydrated silica, so ya get fine grind and polish in the same batch.
Try that in your next tumble. ;D
* often used to whiten skimmed milk, according to Wiki!

When I was a kid, it was supposed to fix scratches on the windshields of model cars.
Not on mine. ;D

When I was in Air Force basic training anyone that smarted off to the squad leader got to remove black heel marks in the morning from the linoleum floors with toothpaste. That may be why my knees are shot. I went through a lot of toothpaste.

As you said Low grade titanium dioxides in paint 20.1% High grade 25% in the latex lines. This is the link i found. graphics.boston.com/globe/magazine/2-18/featurestory5.shtml More bad news, DuPont is buying more, And china, Japan. All are increasing their demands on the market. I have some Glass shops here local, that allow me to clean the sump on the Cerium Oxide tank.

Doesn't really say anything on purity of the titanium dioxide though, does it? Tin oxide will be listed as 99.9% pure for instance. The amount of titanium dioxide in paint doesn't help with polish. Do they make it in different purities? Or, is it just pure stuff anyway?
