This is a question asked on another list I'm on. I don't know the answer
and since controlled burn would be a convenient way to clear brush I'm
curious to know the answer. Anybody? Thanks, Ruth
Controlled burns are used in Dept of Natural Resource properties in about 5
DNR controlled cemeteries in Indiana....the real question has NEVER been
answered by DNR or scientific research....and that is what does high heat
and burning do to the stone and mortars?
