Production
The heating (dry distilling) of wood causes tar and pitch to drip away from the wood and leave behind charcoal. Birchbark is used to make a particularly fine tar. The terms tar and pitch are often used interchangeably. However, pitch is considered more solid while tar is more liquid. Traditionally, pitch that was used for waterproofing buckets, barrels and small boats was drawn from pine. It is used to make Cutler's resin.

Famous quotes containing the word production:
“Perestroika basically is creating material incentives for the individual. Some of the comrades deny that, but I can’t see it any other way. In that sense human nature kinda goes backwards. It’s a step backwards. You have to realize the people weren’t quite ready for a socialist production system.”
—Gus Hall (b. 1910)
“Every production of an artist should be the expression of an adventure of his soul.”
—W. Somerset Maugham (1874–1965)
