I was surprised to see orange when I stirred the ashes. We’ll see how it looks tonight. If it is still really warm, I guess I’ll let the rain cool it off tomorrow. But really hoping we’re done tonight.

Still weighs the same so nothing broke off. Buried too deep, I think. But some changes. I believe the yellow deepened: Don't see much change here other than the possibly the yellow being deeper again: But there is a band of deep purple that I hadn't noticed before on this angle: So are the changes wishful thinking on my part or do any of you see them as well? Trying to decide on a round two with the stone not buried as deeply. Thoughts?

I have the same problem with Costco steaks. They are so thick I can't figure out the proper cooking time. I think we both need some kind of thermal probe.

Toad I tried heat treating rock once or twice with good results (that means I sold them all). For best results get (permission from whoever owns the stove) a pit big enough to hold your rock. Place in pan to bake. Fill remaining space with cheap sand, being sure to cover your rock by about 1 inch. Place in oven and over the next 6 hrs raise the temp slowly to 220 deg F. once it is at 220 deg for an hour raise to 250 for 30 min then bring up the temp to max bake for the rest of the day. when you go to bed turn off the oven and let set int eh oven backing and cooling all night. Next morning check rock should be cooked.

I say bury it again but not as deep. I think it will change more and deeper that way!

I think I will give it one more try in the yard. No way in heck that I am going to put rocks in the oven, will not get permission from the Mrs.

Interesting experiment. There are some color changes. Does the color change amount depend on the temperature, on the time or is it only by chance?

I think rock make-up is involved but that temperature and time are more important. Not all rocks change color with heat but mookaite is one that is supposed to. But may depend on chemical composition. Like one amethyst might have a more saturated color than another.

Had some violent winds come through on Wednesday. Brought down a nice branch from my dead Ash tree. The fire should devour it pretty quick. We're about 6.5 hours into the burn... 9 hours in and have a heap of coals glowing over the rock. I’m wondering if it is getting as hot as last time though. The weather is cooler and much breezier which is probably whisking the heat away. When I get close though it is very warm. And with the rock being closer to the surface, it should be getting a decent amount of heat

Now to wait another 2.5 days before digging it up. Crossing fingers for colors... Stuck my wife's meat thermometer in the ashes (shhhh!) It only goes to 392F. It red-lined in about 2 seconds, so still nice and warm underground.

Such a cool project. I look forward to your results. It got me thinking about giving this a try too.
My home is on an esker, so under the topsoil is sand and small rock. My only fear is catching fire to a tree root, which might burn for a long time on its length before finding oxygen and starting another fire.
One time when I was digging out a plot for new garden beds, I decided to use a similar method to cook a foil wrapped quarter of venison buried in the sand. Parts of it got burned, but the rest was amazing.

I cook wonderstone to improve colors in my turkey roaster. I use kitty litter and run it up as high as it gets. A tad over 500 degrees and I get good colors!

One time when I was digging out a plot for new garden beds, I decided to use a similar method to cook a foil wrapped quarter of venison buried in the sand. Parts of it got burned, but the rest was amazing. In Russia or Germany they use large burdock leaves I think soaked in water over night maybe not soaked then they wrap meats up in, then placing wrapped meat on a bed of coals in the bottom of a pit cover with sand then meat fill hole with sand and or dirt cook for 1-2 days. The burdock leaves act like natural tenderizer as the juices are released from the leaves If you want the directions how on to I do have them in a herbal book

I need to get a better thermometer. The meat thermometer tops out at 392F and almost 48 hours since I stopped adding wood to my 'cook' fire, it still goes off the scale almost instantly. Maybe I overdid it this time... Still soaking in that heat as orrum would say.
