Very nice! What exactly does cooking do to the color of the coral? Does it darken it, or does it change it to a different color?

it changes the color and workability of the rock.Thats why the indians did it from the archaic to the mississippian period.Paleo indians didnt have that technology yet. yellow will cook orange, the browns will turn red that brown chert in the pics will turn red, the clear will turn white. I`m gonna fire another batch this weekend so I`ll do a before and after on some that I will cab

What method do you use for cooking? I did a little research and it seems there are many ways? I'd like to see pictures before and after along with a tutorial!! I have a kiln available, if that helps. Susan

Wow, very cool. I like the last pic. I have a really old stock piece of agatized coral that looks alot like that one, reddish with the little fan-like shapes.
