HIya' Duke.
You know I can't help with the tumbling, but when cabbing some pieces just won't polish as well as others. No matter what you do... .

Shiny is good; so is matte.

A lot of wonderstone just won't take a high polish. I made some pendants a while back that wouldn't polish so I applied a bit of carnuba wax and it looked good.

Same experience. More often than not, matte is as good as it gets. It often has pretty patterns, though.

Thanks All!  Well After Running A Batch in the tumbler I polished them and yes they were Matt. I then went to MR. Cab King and made a couple Cabochons and they were Matt also. so I am currently doing this. It takes a month in the rotary to shape them I use 30 grit for my 1st stage usually 4-6 weeks then I went to 220G with borax for 5 days, Then 500G with borax for 6 days, The .3 micron polish w/ borax for 7 days if that don't do it Ill hafta make a sacrifice to the rock GOD'S. Over the summer I have tried Cerium Oxide, French Cerium Oxide, Chrome Oxide, Tin Oxide, Aluminum Oxide, IN THE FINAL POLISH STAGE...... Ive thrown about everything at it there is except WITCH HAZEL Ive even contacted MERLIN and the Great And Powerful Ozz and Ive run out of options. Ill post my results in a few diays after the 7 days in the .3 micron polish  Thanks ~Duke   |

Duke cook the rock buried in sand in a turkey roaster as hot as it can go. Go up 50 degrees every hour and then let it cool 2-3 days so cold shock dont crack it. The colors will improve and they will sometimes get a much better polish. Merry Christmas to you, MJ and my bestest buddy Bo Bo!!! TheRock |

I haven't done a lot of tumbling but I remember a guy I used to know who did claim that on some of the tough to polish materials that he would tumble polish them dry with cut up pieces of leather and a crushed bar of ZAM (ZAM is a mixture of aluminum oxide & chrome oxide with a wax binder). And sometimes just with plain aluminum oxide. Which makes sense to me because I have found that when polishing cabochons, aluminum oxide on slightly damp leather does a good job on some of the more tough to polish soft materials.

If heat treated it will be softer. It changes color well, beautiful after. and before... I got some New Mexico material and it was well silicified and polished easy. Shaped slow. Got some Montana material and it would only take a nice matte, after cooking it it took a low matte polish. Both shaped quickly. The purple material is Montana and heat treated. The yellowish is from New Mexico and easily polished. Matte or polish who cares, the stone is stunning either way. Yours look awesome. www.flickr.com/photos/67205364@N06/sets/72157649620386342The Montana is at center, the New Mexico is at right. Both in rotary same amount of time but look at how well rounded the softer Montana shaped compared to N.M. rock especially after the Montana was made softer by cooking. I took it to 600F, seemed a good stopping point. Result solid and friendly to knapp.  PS I ran a few of these with glass several times in finish stages in vibe. Glass came out with brilliant polish, Montana rhyolite came out with same damn matte finish go figure. Swinging white flag. |

I went 100F every 4 to 6 hours, held at 600 for 4 hours and cooled it at the same conservative 5hours/100F rate.
Standard 600f/3 day cook used on coral.
Coral will crack if you cool it fast, not rhylolite because of it's grainy structure. Coral is glassy.
Good to see you becoming a rock chef Bob. Rhyolite is a great target to cook.
Coral is submerged in water in most cases. Best to heat it for a couple of days at say 200F(BELOW 212F) to dry it out.
Lest you like rocks exploding in your cooker. Water breaching 212F boils and has a real bad way of exploding you rocks.
If you reduce them to tumble size before cooking instead of cooking 5 pounders you will greatly reduce the chance of rocks blowing up AND get better color.
It like most rocks does much differently if you break it up into tumble sizes before cooking as opposed to cooking chunks and the breaking them up. The first ~1/8 inch of depth normally has a richer cooked color, tumbling the edges off exposes both the inside color and the skin color.
