Just started burning through my stack's and finally came to some Mulberry. I guess i'm just so spoiled by burning Oak most of the time. I can't seem to figure out the Mulberry, it's plenty dry, but it just won't get the secondary's firing in the stove. My Oak and Ash burn great,,,but the Mulberry, not so much. Way to many spark's from the Mulberry when you open the door to the stove, actually pretty dangerous. I would advise to ad a extra layer of protection and eye wear when reloading with Mulberry. Spark's fly out of the stove a few feet past the hearth pad.
