I got some OLD Apricot and peach tree wood from my parents today. It was in an old shed that they had knocked down. My Mom told me that my father cut and split it about 20 years ago! We used to have Apricot trees and Peach trees growing in our yard. The wood is very heavy and burned for so much longer than any wood I have had so far. My stove got alot hotter than usual, I had to shut the air control almost all the way, and the thermometer still said 650. Is it possible for the wood to have petrified? It wasn't rotted at all like you would expect after 20 or so years. I wish I had alot more of it...
