Hot bright flame

Little trick from my years in the military

A little unknown trick if you ever require a flame that burns hot and bright and lasts a long time; use knots (the portion of the branch that is attatched to the tree) from pine trees.

The reason for this is that these knots contain higher concentrations of natural pitch. Which in turn is flammable and it can also be used to make tar.
