Fatwood
Fatwood, also known as "fat lighter," "lighter wood," "rich lighter," "pine knot," "lighter knot," "heart pine" or "lighter'd", is derived from the heartwood of pine trees. This resin-impregnated heartwood becomes hard and rot-resistant. The stump (and tap root) left in the ground after a tree has fallen or has been cut is an excellent source of fatwood. Other locations, such as the joints where limbs intersect the trunk, can also be harvested. Although most resinous pines can produce fatwood, in the southeastern United States the wood is commonly associated with longleaf pine (''Pinus palustris''), which historically was highly valued for its high pitch production. ==History== The commercial use of fatwood from stumps stemmed from its use to make pitch and pine tar. In 1648, a company was formed in Sweden called ''Norrländska Tjärkompaniet'' (The Wood Tar Company of North Sweden), and was given exclusive export rights(pinetar - see separate topic- not fatwood ) by the King of Sweden.
