Pinfire Cartridge
The pin-fire (or pinfire) is an obsolete type of metallic cartridge used in firearms, where the Primer_(firearms), priming compound is ignited by striking a small pin that protrudes radially from above the base of the cartridge. Invented by Frenchman Casimir Lefaucheux in 1832, but not patented until 1835, it was one of the earliest practical designs of a metallic cartridge to hasten the loading and firing process of a firearm. Its history is closely associated with the development of the breechloader, which would eventually replace all muzzleloader, muzzle-loading firearms. The cartridge featured a small pin that, when struck, would ignite the priming compound and initiate the firing process. Despite initial resistance, especially from British gun users, the pinfire cartridge gained popularity following the Great Exhibition of 1851. Its advantages included easier and faster loading than percussion cap, percussion weapons, and it was more likely to fire reliably when wet. Howev ...

Lefaucheux Pinfire Cartridges
Casimir Lefaucheux (; 26 January 1802 – 9 August 1852) was a French gunsmith. He was born in Bonnétable, France and died in Paris, France. Casimir Lefaucheux obtained his first patent in 1827. In 1832, he completed a drop-barrel sporting gun with paper cartridges. Lefaucheux is credited with the development of one of the first efficient self-contained Cartridge (firearms), cartridge systems. This 1835 invention, featuring a Pinfire cartridge, pinfire mechanism, followed the pioneering work of Jean Samuel Pauly in 1808-1812. The Lefaucheux cartridge had a conical bullet, a cardboard powder tube, and a copper base that incorporated a primer pellet. Lefaucheux thus proposed one of the first practical breech-loading weapons. In 1846, Benjamin Houllier improved on the Lefaucheux system by introducing an entirely metallic cartridge of copper brass. In 1858, the Lefaucheux pistolet-revolver became the first metallic-cartridge revolver to be adopted by a national government, becoming ...

Revolver
A revolver is a repeating handgun with at least one barrel and a revolving cylinder containing multiple chambers (each holding a single cartridge) for firing. Because most revolver models hold six cartridges before needing to be reloaded, revolvers are commonly called six shooters or sixguns. Due to their rotating cylinder mechanism, they may also be called wheel guns. Before firing, cocking the revolver's hammer partially rotates the cylinder, indexing one of the cylinder chambers into alignment with the barrel, allowing the bullet to be fired through the bore. By sequentially rotating through each chamber, the revolver allows the user to fire multiple times until having to reload the gun, unlike older single-shot firearms that had to be reloaded after each shot. The hammer cocking in nearly all revolvers is manually driven and can be cocked either by the user using the thumb to directly pull back the hammer (as in single-action), or via internal linkage relaying t ...

Sodium Chloride
Sodium chloride , commonly known as Salt#Edible salt, edible salt, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. It is transparent or translucent, brittle, hygroscopic, and occurs as the mineral halite. In its edible form, it is commonly used as a condiment and curing (food preservation), food preservative. Large quantities of sodium chloride are used in many industrial processes, and it is a major source of sodium and chlorine compounds used as feedstocks for further Chemical synthesis, chemical syntheses. Another major application of sodium chloride is deicing of roadways in sub-freezing weather. Uses In addition to the many familiar domestic uses of salt, more dominant applications of the approximately 250 million tonnes per year production (2008 data) include chemicals and de-icing.Westphal, Gisbert ''et al.''

Corrosion
Corrosion is a natural process that converts a refined metal into a more chemically stable oxide. It is the gradual deterioration of materials (usually a metal) by chemical or electrochemical reaction with their environment. Corrosion engineering is the field dedicated to controlling and preventing corrosion. In the most common use of the word, this means electrochemical oxidation of metal in reaction with an oxidant such as oxygen, hydrogen, or hydroxide. Rusting, the formation of red-orange iron oxides, is a well-known example of electrochemical corrosion. This type of corrosion typically produces oxides or salts of the original metal and results in a distinctive coloration. Corrosion can also occur in materials other than metals, such as ceramics or polymers, although in this context, the term "degradation" is more common. Corrosion degrades the useful properties of materials and structures including mechanical strength, appearance, and permeability to liquids and ga ...

Brass
Brass is an alloy of copper and zinc, in proportions which can be varied to achieve different colours and mechanical, electrical, acoustic and chemical properties, but copper typically has the larger proportion, generally copper and zinc. In use since prehistoric times, it is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. Brass is similar to bronze, a copper alloy that contains tin instead of zinc. Both bronze and brass may include small proportions of a range of other Chemical element, elements including arsenic, lead, phosphorus, aluminium, manganese and silicon. Historically, the distinction between the two alloys has been less consistent and clear, and increasingly museums use the more general term "list of copper alloys, copper alloy". Brass has long been a popular material for its bright gold-like appearance and is still used for drawer pulls and door handle, doorknobs. It has also been widely used to ma ...

Colt's Manufacturing Company
Colt's Manufacturing Company, LLC (CMC, formerly Colt's Patent Firearms Manufacturing Company) is an American firearms manufacturer, founded in 1855 by Samuel Colt that has become a subsidiary of Czech holding company Colt CZ Group. It is the successor corporation to Colt's earlier firearms-making efforts, which started in 1836. Colt is known for the engineering, production, and marketing of firearms, especially during the century from 1850 through World War I, when it dominated its industry and was a seminal influence on manufacturing technology. Colt's earliest designs played a major role in the popularization of the revolver and the shift away from single-shot pistols. Although Samuel Colt did not invent the revolver, his designs resulted in the first very successful model. The most famous Colt products include the Colt Walker, made in 1847 in the facilities of Eli Whitney Jr., the Colt Single Action Army, the Colt Python, and the Colt M1911 pistol, which is the longest ...
