I'm reading careful here too,
my last batch of pitch was bad. cooked on a woodstove in an earthenware bowl. It was full of bark junk , i kept moving the sticky chunks up the sides to let it drip.
I think I added TOO MUCH charcoal and powered roadapple. When heated my glue sticks are still gritty and don't drip. They're hard and shatter like hard gritty gravel!
tried adding beeswax to the mix and it wouldn't seem to mix in no matter how long i mashed it in.
so...I'm listening....
I liked the idea of the two cans, one with the holes on the bottom. Pine is hard to find around this area where Oaks rule.
