This is coral. Not sure how it will work on agates.
May be efficient if rock was soaked in water first. Water absorbed in the fractures quickly separates the rock at fractures at boiling point.
WEAR EYE PROTECTION
This rock riddled with fractures.

And all this time I thought torches were for cutting steel . Don't heat something with a torch on a concrete garage floor . Lots of shrapnel and a big pit in the floor are the result .

Works similar wigglin. Makes dandruff out of coral at high temp(shown). But does split rocks exactly at fractures if you are careful with the heat. Hard to do with hammer sometimes. Soak them for a long time to get water in fractures and I bet they would split at fractures efficiently. Propane would do it. Works great on chert too. I used to split 500 pound coastal chert boulders with a large magnifying glass using the sun. Pop = 2 boulders. Darnedest thing. Sounds so innocent.

Torch heat effect the color of your coral or does that take heating over a longer period of time?

I put wet rose quartz in the freezer over nite and then dump it into a boiling pot of water. Same with flint ridge. It separates the fractures and gives smaller hut more solidnpiefes. I have wondered about this for Rainbow Arizona wood since it fractures up so bad in the tumbler. It's a old ancient man/ Indian trick. I learned it in my first life as a mammoth hunter on the rocky coast of France or was that Belgium? LOL Does Belgium have a coast? LOL. Hmmm maybe that was as a .....

Learn something new, whether worthwhile or not, every day. From what I've seen concrete floors and river rocks in a fire ring do, I think I'd be wearing a bomb suit.

Bad joke to throw a hunk of coral in the fire. Talk about ricochets heading in all directions. Hot ricochets. Happens at hunt camps, parties etc.

Torch heat effect the color of your coral or does that take heating over a longer period of time? It did, but only a thin layer. Must be heated for a long time to get color to the center, especially on big chunks. What I did learn, heat a sample using the torch from a big chunk to get an idea of the color change. You never know completely what color it will go. That second coral turned some fine color, and not expected.

My list of 'gotta try james idea' gets longer by the day Try this one, tell your wife to try brand x laundry detergent so the sheets will smell like an old girlfriend's bed. Much more dangerous than heating rocks to blow up. I think you know better.

That sounds way gentler than the torch technique Bill. Nothing like solid for the tumbler. Wonder if you were doing that to Hog Mine quartz ?

I'll go with the safe idea of making rock shrapnel . Didn't say I would try all your ideas .

I need to make a note to myself if I ever visit a couple of you folks to bring a bullet-proof vest, my son's old paint ball helmet, some epipens, large first aid kit, and a back brace!!

APC (armored personnel carrier) comes to mind A 15 pound coral blew up in the heat treatment furnace one day. You could feel that one from the ground. Dented the wall of the furnace. That was an armor suit explosion.

Hey Jim the Chris the guy that owns the Hogg Mine is who told me about that, makes the rose quartzs break into squares and rectangles.

jamesp does great experiments and has really opened my eyes to different things, but does anyone else think he has too much time on his hands? If given enough time I think he may come up with a cold fusion reactor using various corals and rocks. Jake

All rocks contain a certain amount of water. When heat treating stone for knapping , you heat at about 200 deg. for min. of 2 hours. This removes the water trapped inside.Every 2 hours you ramp up another 50 deg. Most stone needs 2 hours at 500 deg. to get the job done. After the 2 hours are up you cut the heat and leave furnace closed until approximate room temps. are reached. If you cook the stone at 200 for a couple hours the ( popcorn effect ) might be reduced when torched , (probably not). All rock, solid or not is gonna blow when subjected to radical heat like a torch. frost crack surfaces will be discolored when exposed.
I didn't notice any discoloration on the surfaces exposed in the video, this is usually a given when frost cracks are present ! Broken surfaces in the vid. looked like freshly broken material.

Not sure about the whiskey, might need all my faculties about me and might need to be able to move quickly.
