Nixtamalization with Rocket Stove Ash

Howdy Y'all!

I'm looking to do nixtamalization of corn (and maybe wheat?) with the hardwood ash from my rocket stove.  

Is there any danger in this idea?  My ash in my burn chamber is mostly from oak, and is dark grey/black.  At times it hardens up into semi-solid substance (like charcoal), I believe due to high heat for sustained periods of time.

I took off ash this morning from yesterday's burn, and ran warm/hot water over it, and it's been sitting in a jar of water since this morning.

Any thoughts?

Thanks,

Adam

My people nixtamalize with fresh wood ashes. It works fine. We combine the ashes with corn, add water, then boil. The ashes react with carbon dioxide in the air, and become less effective as time goes on, so we prefer to use fresh ashes for nixtamalization.

I've used ash in my grits and cornmeal for many years, and have learned that my food can be gritty if I'm not quite careful about the ash...that there are no little bits of charcoal or dirt in it.  I like pure white ash scraped carefully up with a spoon, etc. from where hardwood logs have burned away in an undisturbed way either in a stove or a campfire.
