Pine tar is a sticky material produced by the high temperature carbonization of pine wood in anoxic conditions (dry distillation or destructive distillation). The wood is rapidly decomposed by applying heat and pressure in a closed container; the primary resulting products are charcoal and pine tar.
Pine tar consists primarily of aromatic hydrocarbons, tar acids and tar bases. Components of tar vary according to the pyrolytic process (e.g. method, duration, temperature) and origin of the wood (e.g. age of pine trees, type of soil and moisture conditions during tree growth). The choice of wood, design of kiln, burning and collection of the tar can vary. Only pine stumps and roots are used in the traditional production of pine tar.
Pine tar has a long history as a wood preservative, as a wood sealant for maritime use, in roofing construction and maintenance, in soaps such as Packer’s Pine Tar Soap and in the treatment of carbuncles and skin diseases, such as psoriasis, eczema, and rosacea.

Famous quotes containing the words pine and/or tar:
“...what a thing it is to lie there all day in the fine breeze, with the pine needles dropping on one, only to return to the hotel at night so hungry that the dinner, however homely, is a fete, and the menu finer reading than the best poetry in the world! Yet we are to leave all this for the glare and blaze of Nice and Monte Carlo; which is proof enough that one cannot become really acclimated to happiness.”
—Willa Cather (1876–1947)
“The master, the swabber, the boatswain and I,
The gunner and his mate,
Loved Mall, Meg, and Marian and Margery,
But none of us cared for Kate;
For she had a tongue with a tang,
Would cry to a sailor, ‘Go hang!’
She loved not the savour of tar nor of pitch,
Yet a tailor might scratch her where’er she did itch:
Then to sea, boys, and let her go hang.”
—William Shakespeare (1564–1616)
