I don't know the market price. please pm your offer. 

Thanks!

Hello. I happen to have a Heat stone. But I'm not sure about the price. Could you probably give me an offer? I suppose we can work out a deal.

Heat stones can be made by those that hold the required tool. Usually you only have to provide memory stones and maybe heat. I think currently Syrian has such a tool.

As for market value. Not much. Unless the supply and demand ratio changes

 

It's good to know. Thank you.

To be fair, I can make Heat Stones as well. And I farm my own memory stones so... They're all essentially free. I plan on being much more active for the perceivable future so, just find me and ask if you're ever in need.
