Sources
The chief region of rosin production is Indonesia, southern China, such as Guangdong, Guangxi, Fujian, Yunnan and Jiangxi, and the Northern part of Vietnam. Chinese rosin is obtained mainly from the turpentine of Masson's Pine Pinus massoniana and Slash Pine P. elliottii.
The South Atlantic and Eastern Gulf states of the United States is also a chief region of production. American rosin is obtained from the turpentine of Longleaf Pine Pinus palustris and Loblolly Pine P. taeda. In Mexico, most of the rosin is derived from live tapping of several species of pine trees, but mostly Pinus oocarpa, Pinus leiophylla, Pinus devoniana and Pinus montezumae. Most production is concentrated in the west-central state of Michoacán.
The main source of supply in Europe is the French district of Les Landes in the departments of Gironde and Landes, where the Maritime Pine P. pinaster is extensively cultivated. In the north of Europe rosin is obtained from the Scots Pine P. sylvestris, and throughout European countries local supplies are obtained from other species of pine, with Aleppo Pine P. halepensis being particularly important in the Mediterranean region.

Famous quotes containing the word sources:
“On board ship there are many sources of joy of which the land knows nothing. You may flirt and dance at sixty; and if you are awkward in the turn of a valse, you may put it down to the motion of the ship. You need wear no gloves, and may drink your soda-and-brandy without being ashamed of it.”
—Anthony Trollope (1815–1882)
“Even healthy families need outside sources of moral guidance to keep those tensions from imploding—and this means, among other things, a public philosophy of gender equality and concern for child welfare. When instead the larger culture aggrandizes wife beaters, degrades women or nods approvingly at child slappers, the family gets a little more dangerous for everyone, and so, inevitably, does the larger world.”
—Barbara Ehrenreich (20th century)
“The sources of poetry are in the spirit seeking completeness.”
—Muriel Rukeyser (1913–1980)
