goes well with sackcloth...
not quite the same as lime, though it has similarities. it does raise pH like lime does, and it's largely calcium carbonate (same as limestone). there's a fair bit of potassium in there, too, and some other odds and ends including heavy metals. it also has in common with lime that over-application can cause troubles. and over-application is pretty easy to do.
other uses include high-temperature insulation (think wood stoves) and soap-making. for
soap,
water is passed through the ashes to obtain potassium hydroxide, which is then reacted with lipids to make soap. not a quick or easy endeavor.
I dump ashes along with charcoal in a corner of the
chicken coop being careful not to send any airborne where it could damage
chicken eyes and lungs. the birds chew up the charcoal occasionally, and slowly spread the ashes out into the rest of the bedding. that way it's all nice and composted by the time any earthworms or plants interact with it after I clean out the coop.
