I have tried the Royal Oak brand of woood chunks, I have tried plain charcaol w/ wood chips in a foil pouch and have had good results.. So I decided to try using charcaol with actual pieces of wood that I have split for my wood stove i the barn, the results did not go in my favor.. I had good temp setting but I kept getting plain white smoke.. So I guess my queston is: when using charcoal mixed with split wood pieces should I be able to produce the thin blue smoke?? If so where am I making my mistake, is it too much air? not enough air? if it is something else PLEASE let me know, any help would be appreciated..
