pigeon blood agate?

<< < (2/2)

Chippintuff:
I have knapped only 3-4 pieces of agate of unknown varieties, and they were difficult raw. The flake scars were dull. It takes more heat than my turkey roaster will produce to get it treated.

most agates require heat in the 4-600 range, I would search for answers before heating known types of agate from other knappers and sources. otherwise it is an experiment  doing successive heats and raising temps until it is found to be done. There are some lists on line here and there of rock heating recipes.

bubby:
I do agate in my roaster comes out good, kinda look's like polkadot agate to me

StevenT:
I contacted Dave on FB and he said it was definitely heat treated. Got any pics of what you have?

StevenT:
Dave posted that he uses a roaster. 225 for 5 hrs to dry out then 485 for 8 hrs. Let us see what you end up with.
