Just buried this coastal byrozoan chert in sand in a coffee can and placed a horse shoe between the can and the stove for a day Looks like 550F to 650F. Specimen started all yellow to brown. No reds or greens before heat. Circle of red to left looks as if fractured before heat and got hotter than same material to right. Or the fracture absorbed more metal salts and was effected by the heat more. Can control heat by adding metal spacers to isolate from stove. Results surprisingly good. This piece was split after cooking. Notice dark red skin to the far left. Exposed skin on nodules get false color on the surface. Gotta crack em open to see the results internally.

the adventure continues! Is that the first greenish coral? Scott, that is coastal plain chert(Savannah River Agate). It is a smorgasbord of sea life. Famous for bryozoans. I believe 12 bryozoans were known to exist till they found 9 more in this stuff. It never occurs green, red, or dark purple unless cooked. It is full of iron salts and goes crazy w/heat I guess. The green is bizarre. I do not know where it comes from.

If this would not have been posted by you; I would have thought of Dino poop at first sight. Does not look like coral to me without the usual structures.

These are the same colorful tumbles i have posted before Scott. This stuff is an agate in our red clay instead of sand. Way up past the red clay line which is rare. Like way far north probably where the ocean crept up the Savannah Valley. It is low land but well north past most of the ancient ocean sands in the southern half of the state. Betting the metal/mineral rich clays effected this material. The same red clay that grows delicious tomatoes, corn, and other vegetables. Probably because it is very rich in chelated micro nutrients

Rarely bivalves. And that is odd. Spiral shells(snails). Lots of micro stuff too. But i see why you would say poop. As mentioned above, it was famous for having 9 newly discovered fossil bryozoans. This was found in a 20 square mile ancient mine that was used by native people. I find artifacts made of it 200 miles away here in Atlanta. Look at all the action. This stuff is crazy Lots of fossils in more of the same material www.flickr.com/photos/67205364@N06/8250677108/in/set-72157632182662877/

That's a beautiful coral specimen, I would polish the face & display it. And, where else would comparing something to poop be a compliment?

That's pretty cool. I've always wanted to try that with lighter colored Carnelian. I wonder if a more brownish colored piece of sard would phase red or just turn a darker brown...

I would cook those carnelian tumbles in a heartbeat. The yellow and orange may do best. Reds risk turning brown. Collect some rough and try it. A mix of other stuff too. Your agates from lava formations seem better at 350-450F(hotter and they turn ugly brown). Precipitated from limestone agates we have like 550-700F. You can experiment on a small scale.

About all jobs are a lot more complicated than they look.
