titanium oxide is no longer on the market - thus the titanium dioxide which i haven't tried yet as i still have the titanium oxide. but i will get the dioxide when i run out of it. it gives an beautiful shine on most rocks but if they have a crack or pit polish gets in it and won't come out. the tin oxide is a completely different polish - a very good polish but expensive. this list will tell you which polishes are good for different rocks. the "TO" on the list is for tin oxide. maybe the titanium wasn't around when they made this list. www.utahrockhounds.com/tooelegem/tips/stonepolish.htmlkim

hey, being as the titanium dioxide isn't included in the list that kim hyperlinked, does anyone know how titanium dioxide works with obsidian. I don't want to have to buy the tin... its expensive.

here is a rather interesting link about poishing, quite informative.... users.lmi.net/~drewid/DF_COMPOUNDS.htmli am currently running a batch of obsidian at the moment in coarse, second batch actually, to get enough to move on to medium grind. i was going to use Tin Oxide, as i'd heard that that was the only thing to use with obsidian, but this article tends to have a different view? good luck!

I have used Cerum Oxide on all of my stones and the only ones that didn't take the polish was the Sodalite I tumbled (3 pieces). Tami

Hey Kd, I've been gone for a few days and just got back. I have read a lot of stuff that Friesen had written about polishing rock. Here is an article that he published about Obsidian in particular. I have forwarded this article to others that have asked for help on obsidian.
Ron
"Polishing Obsidian- by Richard Friesen
Obsidian is a volcanic glass which often contains attractive colors and inclusions, but has a reputation as being difficult to polish, although it is fairly soft and is usually uniform in structure. When people are having problems polishing obsidian, I find it is almost always because they didn't get the sanding done adequately before attempting to polish. Obsidian seems to show fine sanding scratches, especially the 600 grit ones, as a haze that won't polish out. A ten-power glass will usually show the problem, although many people won't see it until it is pointed out to them. More time on the 1200 grit wheel usually takes care of the problem. For best results I like to add some time using 3000 grit and then start to polish.
I have used cerium oxide and aluminum oxide to polish obsidian; both work. I like aluminum oxide better. For a real treat, polish a piece of obsidian with cerium oxide, then polish again with Reynolds* .2 micron polishing compound. When I've done this, I often have trouble finding the surface with a ten-power loupe.
By Dick Friesen
*Reynolds has a set of polishes available through Diamond Pacific (Diamond Pacific Tool Corp., 2620 W. Main St., Barstow, CA 92311 (800)253-2954)"

thanks, Ron!
where have you been?
i am going to try to treat this batch with kid gloves and give it all the attention it deserves.....i haven't had a lot of luck with the softer stones, save the sodalite, so we'll see.
thanks for the tip, KD

Very instructional topic, I was even confused with the oxide and dioxide and ended ordering the tin, I will use it with moderation By the way....I never seen or heard about the Reynolds* .2 micron polishing compound. Is that a hand polish or a grit powder for the tumblers? So many new things to learn about! ;D

Hey KD, I've been away for a few days. Back in June, my father-in-law died and my wife now has a place in northern Michigan. It has really been let go, so I've been going up and trying to get some things fixed up. I went up the end of August and had a local guy redo all of the plumbing. I have cut down eleven dead trees so far, and there are at least two more to go. With my MS, I am a lot slower at getting anything done than I used to be. I just keep pecking away at it and resting fequently. I may be slow, but I'm persistent.
I have a batch of Mahogany Obsidian that I have been working on. It is through the 1000 grit, and now it's been waiting for me to have time to get back to it. I don't want to start the polish until I'm ready to pay closer attention to it. I will be using Tin Oxide when I do start it.
Ron

By the way, I believe that the Reynolds polishs that Mr. Friesen refers to are what's commonly called the Linde polishes.

that Linde stuff is what they sell by the ounce/gram.....and i thought the Tin Ox was expensive!
I may be slow, but I'm persistent.
good luck with all your endeavors, Ron, post the obsidian when you get a chance....thanks,
KD
