I'm having some trouble annealing some found steel. One is a trap spring and the other a piece of crosscut saw. I heat to non magnetic and bury in ashes. A couple times now and the steel comes out too hard to file. I'm thinking the ashes are too cold, I keep them in my shop and it's 10 degrees in there. So I heated some scrap steel and warmed the ashes up a bit and still no luck. I'm going to bring a bucket of ashes in to the house and anneal in the basement. Any thoughts?
