Crazy man... Glad your ok! Thanks man. It was safe in that oven. But at an open camp fire it would have hurt someone. It really went in all directions.

Yup, just water that has/had enough power to power the world for many years. I've seen pics. of steam logging donkey boilers that blew up, nothing to fool with. Pressure tanks speak volume when they blow.

I had a feeling that was why but wanted to ask. Thanks for posting pics, what a difference! Beautiful

James, maybe you need to build a safety cage around your oven? Water+ heat = steam + pressure = bomb. Ouch! Glad there were no casualties. also = volcanoes going nuclear! We are lucky water only (?) expands 2,000 X on transition point changing to steam.

Molten rock specific gravity depends on temperature and pressure. The more the rock expands, the lighter it gets, and is able to float up like a ball held under water. When it reaches rock layers with the same density it stops. Subducted rocks contain more moisture than mantle rock, and therefore lower density, and will rise higher = andesite and granite plutons. If groundwater reaches it while still HOT, Etna, St Helens, and soon Yellowstone again. BTW, did you see "Watermelon Popping" in my Family Fun post?

All makes sense Dave. I wonder if Old Faithful fed water to the boiler ?

Next time anyone wants to cook a rock in the family oven when the wife (or significant other) is away they should read this post first. Wouldn't it be fun trying to explain why a new oven is in place when the wife returns from a trip?
Thanks for the post and life lesson.

James, how can that be prevented in the future? What a surprise!
Your heat treated corals are outstanding.

I would be in the dog house if that had happened in the kitchen oven for sure.

Or leave it out in the sun for a year or two. if you go over 212F you risk steam buildup, and the hotter the more steam pressure. I did not notice that coral was really porous. But you never know for sure. Or cook it in a steel container full of sand. I tossed that one on top of the sand covered corals as I normally do on the 4-12 pound chunks.

Interesting to see this. As others have said, glad you are OK!

Hi Jamesp -
I just wanted to point out that the strongest part of a steel structure is the welded joint (assuming it was properly welded ).
The only possibility is that it was either not welded properly causing the weld to come apart or, more than likely, the force was so extraordinary that blew out the strongest part of the container.
I can't imagine that force.
