All those unopened boxes of Rio Grande treasures and you are playing with coral? silly Taking a break from the Rios or just something to keep you busy as the Rios tumble? Wonder how such heat treating would effect Tampa Bay corals. Does the heat treatment make the coral more fragile, tougher or no difference? Tumbling Rio's. Heating the corals. Two separate games. The heat treating is passive and easy to do. Set rocks aside for later. Tampa Bay material is excellent candidate. Salt water has tons of chemicals and makes wild colors. Yes, you risk cracks and it does make the stone more brittle. But coral still remains tough after cooking. I have seen your pile of Pasco Hillsborough and Tampa coral. They would be as good as it gets for cooking. I would collect in Pasco and Hillsborough most of the time if I had land permission. Best coral.

James. Gem enhancement is a problem in that I don't collect them. I have large sources of heat able chert and coral. Just a lowly tumbler person. Ha, may not have the nerves to stick a bunch of rubies and zircons in an oven.

Ha, may not have the nerves to stick a bunch of rubies and zircons in an oven. I just posted those as examples of oxidation and reduction to alter colors in stones. I think it would be interesting to see what effects you get from reduction heating of corals. For example it could reduce the iron oxides/hydroxides to elemental iron giving it a neat metallic look. Don't know until you try.

Ha, may not have the nerves to stick a bunch of rubies and zircons in an oven. Go to wife unit jewelry box. Gather all within. Heat treat in microwave for 17 minutes. (don't worry about the noise and sparks) Report back here on results. Could be the experiment of the year. I'll wait.

Don't know until you try. I will take time and study this subject James. It is technical and will require attention. Yes, process applied to cryptocrystalline stones must be tried. Thanks for bringing this up.

She has an expensive restaurant grade convection 1/4 oven that did a great job. She fussed about sand in the oven and on counter top quite regularly. She barely lets me make deer jerky in it. Microwave ??

Had Columbus had an attitude like that, we would all still be living in Europe.

captbob, you need some meditation stones for smoothing abrasiveness. Maybe taking larger ones orally.

Very interesting. Some of those madagascar agates look impressive. Although I hate artificially altered stones, I'll probably buy some just to see how they look in person. Strange to buy a stone mined in Africa, shipped to China, and then back to the US. Went over some of stonemaster499's old posts. Seems like he uses 350lb capacity rotary tumblers which he seems to suggest is significantly faster and more efficient. Having a tumbler that large must be nice for tumbling large stones as well. Maybe one of these days haha..

Like any abuse I can get.

Only this one dyed, the rest are cooked. Those agates are typical and common colors produced by heating. The SE US corals are actually of abstract colors. Attracted me to heat treatment. On 3 occasions I have found a pretty big coral head that changed to very odd attractive colors. Problem is I can't find more of them. Frustrating. Dyed Madagascar

Maybe one of these days haha.. Stonemaster a trip. He has some serious rotary and vibratory tumblers. He gets to mine o lot of his stone right there in Madagascar. Never have seen the fortified agate you have pointed out. Sure would like to have some round to tumble. I see the Africa-China-US path. Lots of ground covered. Not sure about a 350 pound tumbler. Feeding/unloading, lots of work.
