            Roofing tar sounds messy but at the right temperature becomes
very solid. The body temp.
is 98.6 (on average) This tar many years before bubble gum was chewed in
the mouth's of our
forefathers... Yes it sounds strange but true.. As a matter of fact I have
chewed tar, as a recommendation
of a forefather when I was very young..... No sugar,... very stiff,.. kinda
bland... I decided it sucks as
a chewing gum but you may have found an alternative purpose other than
sealing your roof or
sealing your teeth....  If you can make sure of the purity, or filter the
heated liquid enough, you may have
an alternative to expensive pitches that are sometimes over priced because
of low demand.
Also , maybe you can experiment with mixing Tar with other products...ie..
beeswax...other pitch
products,.. as long as you can cut them with tupentine they will mix...
