Have you tried a Dynavap? They are great for bubble hash. They heat it enough to vape, but it won't melt too much, and the flavor is so good. I just sprinkle a tiny bit of flower over the screen so the hash doesn't stick to it and then fill the bowl without packing it with the crumbled bubble hash.Hard to really get a distinct taste as I don't have any decently cleaned bowls. However, potency is 100% there. Will give a better report once it has fully dried and I get a clean glass piece.
