leapingbare and sawfiler have heat treated it a lot. I have a little, usually around 450 dgs.

Depends on the grade of the horse creek.
If its glassy dont take it over 350
If its the normal stuff and a little rough than 500 works good.
If its very rough and you got it from that guy on paleoplanet then its called pony creek and needs about 700*
Be sure to alow enough drying time atleast 5 hours at less then 250. some people like to ramp up the heat slow after that but ive learned that aslong as you ive it ample drying time at about 200 then you can go ahead nd ramp it up to the hold temp. i'd let it soak at the hold timp for about 8 hours and then just turn off the heat and give it 12 hours to cool. 20 hours if your useing a kiln and went to 700.
 Hope this helps.

anouther note. The hotter you cook it the the more color change you will get. This is not a good thing when cooking horse creek.
 your reds will turn violet and your greens will turn dark almost a brown color and the yellows will dull out to.
Its best to give it just anough heat to allow you to work it but not enough to change the color. Most color change happens at about 450 on horse creek.
 Pony creek is different and the colors will become a little more vibrante with heat and the greens will sometimes turn a turquoise color.

I have some horse creek i want to heat treat, its the dead of winter where i am, can i cook it in my stove with sand in a giant turkey pot? Or should i wait till summer and do it the old way, bury it and cook it. And what is the difference between pony creek? the stuff i have is a mixture of the usual HCC some very grainy and some what looks pretty decent and two big yellow pieces that look very similar, but has some light red but mostly yellow, i did get it of a guy on paleoplanet, not sure if its the "guy" leapingbear speaks of. I have about 20lbs of the material and in no real rush to make it into gravel either.
