    en.wikipedia.org/wiki/Naval_stores_industry

    It does this by collecting and processing organic forest products refined from slash pine and longleaf pine trees (genus Pinus). The naval stores industry was associated with the maintenance of the wooden ships and sailing tackle of pre-20th century navies, which were caulked and waterproofed using the pitch (a product made with tar) of the ...

    en.wikipedia.org/wiki/Naval_stores

    Pine trees especially in North Carolina were tapped for sap which was doubly distilled to make turpentine and rosin (aka resin)–hence the name tar heels. The trees were scored with a ledge called a “box” to collect the sap. Large numbers of slaves were used to score the trees, collect and process the sap. Zallen describes this as ...

    en.wikipedia.org/wiki/Pitch_(resin)

    Pitch is a viscoelastic polymer which can be natural or manufactured, derived from petroleum, coal tar, [1] or plants. Pitch produced from petroleum may be called bitumen or asphalt , while plant-derived pitch, a resin , is known as rosin in its solid form.

    Monotropa hypopitys, the so-called Dutchman's pipe, false beech-drops, pinesap, or yellow bird's-nest, is a herbaceous perennial plant, formerly classified in the families Monotropaceae or Pyrolaceae, but now included within the subfamily Monotropoideae of the family Ericaceae.

    The collected sap is then boiled. As the sap boils, the water is evaporated off and the syrup left behind. 40 litres (8.8 imp gal; 11 US gal) of maple sap are required to be boiled to produce only 1 litre (0.22 imp gal; 0.26 US gal) of pure syrup. This is the reason for the high cost of pure maple syrup.

  7. Fatwood - Wikipedia

    en.wikipedia.org/wiki/Fatwood

    Coniferous tree sap is a viscous liquid that contains terpene, a volatile hydrocarbon. Over time the evaporation of the terpene changes the state of the sap; it slowly gets thicker until it hardens into resin. New fatwood leaks the sticky sap, while in aged fatwood the sap has hardened and is no longer sticky.

  8. Rosin - Wikipedia

    en.wikipedia.org/wiki/Rosin

    Rosin (/ ˈ r ɒ z ɪ n /), also known as colophony or Greek pitch (Latin: pix graeca), is a resinous material obtained from pine trees and other plants, mostly conifers.The primary components of rosin are diterpenoids, i.e., C 20 carboxylic acids.

  9. Acer saccharum - Wikipedia

    en.wikipedia.org/wiki/Acer_saccharum

    Other maple species can be used as a sap source for maple syrup, but some have lower sugar content and/or produce more cloudy syrup than these two. [23] In maple syrup production from Acer saccharum, the sap is extracted from the trees using a tap placed into a hole drilled through the phloem, just inside the bark. The collected sap is then boiled.
