To tap into the sap producing layers of the tree, harvesters used a series of hacks to remove the pine bark. Once debarked, pine trees secrete crude turpentine onto the surface of the wound as a protective measure to seal the opening, resist exposure to micro-organisms and insects, and prevent vital sap loss. Harvesters wounded trees in V ...
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 ...
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 ...
In the United States the pine tree Pinus palustris, known as the longleaf pine, once covered as much as 90,000,000 acres (360,000 km 2) but due to timber harvesting was reduced by between 95% and 97%. The trees grow very large (up to 150 feet), taking 100 to 150 years to mature and can live up to 500 years.
With the best artificial Christmas trees, you don’t have to worry about sticky sap or pine needles on your floors, forgetting to water the tree, or dealing with disposal when the holiday season ...
Resin extraction – Process of collecting sap or resin from pine trees; Balsam of Peru – Type of tree balsam – used in food and drink for flavoring, in perfumes and toiletries for fragrance, and in medicine and pharmaceutical items. Mastic (plant resin) – Resin traditionally obtained from the mastic tree on the island of Chios
Pine oil is an essential oil obtained from a variety of species of pine, particularly Pinus sylvestris. Typically, parts of the trees that are not used for lumber — stumps, etc. — are ground and subjected to steam distillation. [2] As of 1995, synthetic pine oil was the "biggest single turpentine derivative."
Pine tar is a form of wood tar 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 .
