Pine Tar

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 tar and/or pine:

    The mob is man voluntarily descending to the nature of the beast. Its fit hour of activity is night. Its actions are insane like its whole constitution. It persecutes a principle; it would whip a right; it would tar and feather justice, by inflicting fire and outrage upon the houses and persons of those who have these. It resembles the prank of boys, who run with fire-engines to put out the ruddy aurora streaming to the stars.
    Ralph Waldo Emerson (1803–1882)

    ...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)
