Black oxide provides minimal protection against corrosion, unless also treated with a water-displacing oil to reduce wetting and galvanic action. In colloquial use, thin coatings of black oxide are often termed "gun bluing", while heavier coatings are termed "black oxide". Both refer to the same chemical process for providing true gun bluing.

Like hot black oxide, mid-temperature black oxide converts the surface of the metal to magnetite (Fe 3 O 4). However, mid-temperature black oxide blackens at a temperature of 90–120 °C (194–248 °F), [6] significantly less than hot black oxide. This is advantageous because it is below the solution's boiling point, meaning there are no ...
Bluing is most commonly used by gun manufacturers, gunsmiths and gun owners to improve the cosmetic appearance of, and provide a measure of corrosion resistance to, their firearms. Bolt action: A type of firearm action in which the firearm's bolt is operated manually by the opening and closing of the breech with a small handle.
Black powder substitutes are measured by volumetric measurement techniques, not in grains on a scale, due to the difference in density compared to black powder. For example, to measure a "60 grain equivalent" of black powder substitute suitable for use in a muzzleloader rifle, one uses a volumetric measure that produces a volume of black powder ...
Ivory powder measure used to provide a uniform amount of gunpowder for a muzzle-loading firearm before cartridges were available. A powder measure is a device for dispensing consistent amounts of smokeless powder or black powder as charges for handloading cartridges used as small arms ammunition.
Glock 17 pistol with a black Parkerized topcoat. Glock Ges.m.b.H., an Austrian firearms manufacturer, uses a black Parkerizing process as a topcoat to a Tenifer process to protect the slides of the pistols they manufacture. After applying the Tenifer process, a black Parkerized finish is applied and the slide is protected even if the Parkerized ...
Make your life easier with a tape gun. An essential item for any work space or home, tape guns make sealing boxes a simple task. Invented in 1932 by an engineer at the 3M Company (which remains ...
Because of their similar use, both the original black powder formulation and the smokeless propellant which replaced it are commonly described as gunpowder. The combustion products of smokeless powder are mainly gaseous, compared to around 55% solid products (mostly potassium carbonate, potassium sulfate, and potassium sulfide) for black powder ...
