Took the rocks out.Some changed colors,some didnt.That was the main thing I was after in this round.And the winner is..  Golden palm before  After  Coral chunk from Jason before  Some coral slabs before  The coral after  Mookaite before  After  Brazilian slabs also had a substantial change  After    Really liked the change in this Amazon jasper  Flint Ridge before  After  Was really hoping the chert nodules that I have access to tons of them would change.Did a little! Enough for now! Its been a fun weekend!!  snuffy |

The brazil agate is the best -for that agate it did real good.The coral did great.The palms are hard to see ,i think the small one turned red.Red is nice if that is their color.It is not the best thing to do yellow and red rocks,they often just turn all red.
Will you do it again?Did it turn like you expected?

The reshoot is better on the palm .I find that one end has better color on large rocks-sometimes way better.Or both ends.Bet that small piece is an end.The palm l seems to have a similar texture as coral.Those slabs are real fine.

Interesting. Glad you explained the rug. Do you think the sun/shade difference that affected the rug affected the photo of the rocks, too?

Thanks, Snuffy.
I guess if it’s yellow, let it mellow . . . at room temperature.

I think the carpet square color was more off than the rocks Seems the shade and sun throw it off more.But heck,I aint no photography expert!Usually dont take photos different times of the day and days apart! snuffy |

If you cook slabs or rocks that have absorbed rock saw oil you usually get dark layer.My saw runs in kerosene and it puts a real dark layer on the outside.Best to cook chipped material or whole pieces and saw afterwards.Or use water only saw cuts.Never thought about it till jc said something about using only water in his saw maybe to keep absorbant coral from cracking.But kerosene leaves dark brown layer...( i know the down side of kerosene/gear oil mix).

Looks like everything came out great Snuff!! Looks like you had a good variety in there. I do mostly the Flint Ridge, but now I might try something differant!
I will have to do a little digging in my flint knapping books, but I have a few pages that show cooking temps and times for all differant types of rocks. I think I might have a couple of links to websites for it too. I will look them up and try to get a post up in the next couple of days.

Snuffy, what color did they come out wet? Do they darken to red? I'm curious why everything turned that pinkish rust color. I didn't get any pinks at all with the coral.
It's great that you had no fracturing, that slow cook seems to help a lot:).

Nice results, I like the palm. Looks like everything came out great Snuff!! Looks like you had a good variety in there. I do mostly the Flint Ridge, but now I might try something differant!

Does anyone know what's actually making the coral and other stones here turn orange? Is it iron do you think? |

Yep,it's mostly iron.yellow does orange,orange does red,brown does red/brown,black often does bluish,clear does white often.Probable that other chemicals/metals/salts cause change.Iron is a guarentee,and it is a common coloring agent.Often dull brown,yellow,orange colors really come alive.That palm is a great example,but it was nice before heat.
