RE: Potash
Some treated wood contains arsenic which, as I understand it, does not
disintegrate or burn off in a fire. Arsenic is poisonous to most living
things if the concentration is high enough. As a precaution, I never burn
treated wood in my woodstove so that I can use the ashes.

Hello,
Regarding wood ash... How safe is it to use wood ash from pressure
treated wood?
Are the chemicals used to preserve the wood destroyed by heat and fire?
I don't make a habit of buring this stuff, but a piece of scrap wood will
sometimes make it into the fire pit.
Any thoughts?
Regards,
Tom
