	Apparatus for unidirectional infiltration of preform with molten resin or pitch - Patent 7252499
		Apparatus for unidirectional infiltration of preform with molten resin or pitch
		Thus this invention provides a rapid resin or pitch transfer molding apparatus that includes: an extruder; a mold arranged so that resin or pitch can be extruded from the extruder into the mold; a press to constrain the mold during resin or pitch injection; and a heat exchanger for the extruder and the mold.
		Resins that are contemplated by this invention include thermoplastic and thermoset liquid precursors such as for instance phenolic resins, furfuryl resins, and pitches derived from coal tar and petroleum.

	Society of American Silversmiths - Silversmiths Pitch Review
		Pitch is used all over the world by goldsmiths and silversmiths to hold metal in place while working it with hammers, punches or chisels.
		You want to be able to heat pitch with a hair dryer or heat gun to keep away from the temperatures at which molten spatters of pitch can burn you severely-hence the desire to have a low-temperature warming pitch.
		There are two basic kinds of pitch out there, an asphaltum based one (the usual in North America) and "real" pitch, pine resin (for stickiness) mixed with a fat or grease (for elasticity) and a powder, flint, plaster, brickdust etc for resistance and body.

	Epoxy Resin vs. vinylester - polyester resin
		Even though the resin is still incredibly strong with additives that facilitate curing and allow us to apply it without heating it up, it is not as strong as the epoxy resin SR uses.
		Vinyester resins offer better resistance to moisture absorption than polyester resins but it's downside is in the use of liquid styrene to thin it out (not good to breath that stuff) and its sensitivity to atmospheric moisture and temperature.
		As vinylester resin ages, it becomes a different resin (due to it's continual curing as it ages) so new vinylester resin sometimes resists bonding to your older canoe, or will bond and then later peel off at a bad time.

	Sequoia Pitch Moth Management Guidelines--UC IPM
		Infestations are recognizable by the gray, pink, reddish, or yellowish pitch masses that protrude from infested trunks and limbs.
		Unlike the distinct protrusions caused by bark beetle pitch tubes and sequoia pitch moth pitch masses, injuries, and pathogenic diseases usually cause bark to become coated with a thin layer of resin resembling thick syrup.
		Pitch canker can infect pine tissue of any age, including young branches and terminal shoots the diameter of a pencil; bark beetles and sequoia pitch moth primarily attack the main trunk, though sometimes large limbs several inches in diameter can also be attacked.

		If Noah's pitch were to be proven to be an oil product, it would hardly discount the flood account or young earth theories, it would only force some young earth creationists to reevaluate their theories concerning the origin of petroleum or to look into other ways that oil could be produced.
		A tenacious resinous substance of a fl or brown colour, hard when cold, becoming a thick viscid semi-liquid when heated; obtained as a residuum from the boiling or distillation of tar, also from the distillation of turpentine; used to stop the seams of ships after caulking, to protect wood from moisture, and for other purposes.

	FAQ About Pitch Canker
		Pitch Canker is a disease, which causes die-back of individual branches (figure 1), leading to a general decline in tree health, and, in some cases, premature death.
		Many of these insects are known to transmit the pitch canker fungus to healthy trees and are considered to be the primary means by which new infections are established.
		In cases where the incidence of pitch canker is isolated, the timely removal of diseased branch tips may be effective in slowing the spread of the disease.

		It is for this definition of pitch and resin-bonded magnesite-carbon brick and shapes and carbon-magnesite brick that the aggregate latent demand estimates are derived.
		Based on the aggregate view of pitch and resin-bonded magnesite-carbon brick and shapes and carbon-magnesite brick as defined above, data were then collected for as many similar countries as possible for that same definition, at the same level of the value chain.

		The core ingredient of a tree resin pitch is gum rosin [6] which can be extracted from a variety of tree species, notably pines.
		Although not stated explicitly, it seems the job of the pitch was to waterproof the ark, which is the usual role of pitch in shipbuilding.
		Rosin is a brittle and friable resin, with a faint piny odor; the melting-point varies with different specimens, some being semi-fluid at the temperature of boiling water, while others do not melt till 220 or 250 F. It is soluble in alcohol, ether, benzene and chloroform.

	Identifying Fresh Attacks
		Pitch tubes - When trees are not under stress, they will generally respond to SPB attack by producing moderate to copious amounts of resin or pitch which flows out of the bark from the entrance holes produced by attacking beetles.
		If pitch tubes are yellow in color, hard to the touch and crumble when crushed in the hand, the tree is not a fresh attack.
		The old pitch tubes are from the previous fall and the new pitch tubes are most likely from reemerging adults from the same tree attacking a previously uninfested portion of the bole.

		When a tree has a good supply of moisture, sufficient pitch or resin will be produced such that a glob of resin, called a pitch tube, will form where the beetle attacks the tree.
		By contrast, the southern pine beetle tends to attack in the crevices between the bark plates and their pitch tubes are generally a creamy white color.
		However, during periods of drought, pitch tubes may not form on the bark of the trees and only the boring dust and small round holes (about the size of a pencil lead) will be visible.
