Rosin
 |
Rosin (/ˈrɒzɪn/), also called colophony or Greek pitch (Latin: pix graeca), is a solid form of resin obtained from pines and some other plants, mostly conifers, produced by heating fresh liquid resin to vaporize the volatile liquid terpene components. It is semi-transparent and varies in color from yellow to black. At room temperature rosin is brittle, but it melts at stove-top temperature. It chiefly consists of various resin acids, especially abietic acid.[1] The term colophony comes from colophonia resina, Latin for "resin from Colophon" (Ancient Greek: Κολοφωνία ῥητίνη, romanized: Kolophōnía rhētínē),[2][3] an ancient Ionic city.[4] It is an FDA approved food additive.[5]
