- Cone 6-10 is a temp. range If your clay is 6-10 that means it can be fired within that temp. Ive pit fired before and had some success.... but, there is a problem with thermoshock and uneven temps throughout the trash can. my best results were firing the can with wood and letting the coals die down a bit. also in your clay body. add alot of silica/sand in. that is what halped me.... its not an exact science with it, but the most fun is trying to just go crazy with it....[in reply to julie]

- You could maybe trash can fire this clay if you were only making decorative items from it and they didn't need to hold water or food. I have never used Blackjack clay so i don't know how much grit and grog the clay has, the more tooth(grit and grog) a clay has the better change it has of surviving primitive firings. If you wanted to take it to th manufacturer suggested firing range then a electric or gas kiln will be needed. To see what temps those cones refer to please see the following linked chart. Remember tho look for cone 6-10 not cone 06-010 because cone 6-10 is much higher.

Cone 6 -10 means it will be great at all temps in this range. But if you would like to ask the manufacturer.

I don't know where you are but check here to see if there are any kilnshares in your area that will fire to the cone you need.

- I am really just looking for expertise. I was able to acquire a bucket of blackjack clay from Craigslist. Although I have an art degree and really took to clay building in college I remember very little about the details of firing. I believe it is a 6-10 cone? What can you tell me about getting this clay fired as well as possible limitations on glazing. I would really prefer a clay I can trash can fire but I'm assuming this clay needs too high of a temperature? What is the temp for level 6 vs. level 10?? What is the best temp/level for this clay?
