Cordite Cordite is a family of smokeless propellants developed and produced in the United Kingdom since 1889 to replace gunpowder as a military propellant. Like gunpowder, cordite is classified as a low explosive because of its slow burning rates and consequently low brisance. These produce a subsonic deflagration wave rather than the supersonic detonation wave produced by brisants, or high explosives.

Conglomerate Tillite is a lithified till (poorly sorted glacial debris) which may be called a matrix-supported conglomerate if there are enough granules, pebbles, cobbles, and boulders present. At least 30% of the rock should be composed of clasts larger than 2 mm in diameter in order to call that rock a true conglomerate.Conglomerate from the Ordovician near Bergen in Norway. The clasts are made of quartzite and are slightly flattened due to metamorphism.onglomerate is composed of clasts larger than 2 mm which is the upper limit of sand grains size. Conglomerates are differentiated from sedimentary breccias which are composed of angular clasts.

- Magnetite, also known as magnetite black sand, is a form of iron oxide. It is a very stable and dense material, and is widely found in nature across the world in a variety of natural settings as a commonplace mineral; it most commonly occurs in nature in a granular form as a sand or grit.

- Howlite, a calcium borosilicate hydroxide (Ca2B5SiO9(OH)5), is a borate mineral found in evaporite deposits.[4] Howlite was discovered near Windsor, Nova Scotia in 1868 by Henry How (1828–1879), a Canadian chemist, geologist, and mineralogist.[5][6] How was alerted to the unknown mineral by miners in a gypsum quarry, who found it to be a nuisance.

- Tannerite is an explosive that is designed to be detonated by the impact of a rifle bullet. It's shipped as two separate bottles of different compounds which, individually, are not explosive. When the two compounds are mixed, they become an official explosive.

What Is MasoniteÂ® Board? Masonite® board is a composite wood product that is similar to hardboard or fiberboard. It is sold in sheets like plywood or particle board, but is constructed quite differently from these products. This product is made using shredded wood chips, which are heated and mixed to form fine wood fibers.

- Silicon carbide (SiC), also known as carborundum /kɑrbəˈrʌndəm/ , is a compound of silicon and carbon with chemical formula SiC.It occurs in nature as the extremely rare mineral moissanite.Silicon carbide powder has been mass-produced since 1893 for use as an abrasive.ilicon carbide is used in carborundum printmaking – a collagraph printmaking technique. Carborundum grit is applied in a paste to the surface of an aluminium plate. When the paste is dry, ink is applied and trapped in its granular surface, then wiped from the bare areas of the plate.

Bainite Bainite is an intermediate of pearlite and martensite in terms of hardness. For this reason, the bainitic microstructure becomes useful in that no additional heat treatments are required after initial cooling to achieve a hardness value between that of pearlitic and martensitic steels.he amount of ferrite that forms between the laths is based on the carbon content of the steel. For a low carbon steel, typically discontinuous stringers or small particles of cementite will be present between laths. For a higher carbon steel, the stringers become continuous along the length of the adjacent laths.

Silicon carbide Silicon carbide (Si C), also known as carborundum, is a compound of silicon and carbon with chemical formula SiC. It occurs in nature as the extremely rare mineral moissanite. Silicon carbide powder has been mass-produced since 1893 for use as an abrasive.lpha silicon carbide (α-SiC) is the most commonly encountered polymorph; it is formed at temperatures greater than 1700 °C and has a hexagonal crystal structure (similar to Wurtzite). The beta modification (β-SiC), with a zinc blende crystal structure (similar to diamond), is formed at temperatures below 1700 °C.

- No, it's not the answer to a Jeopardy question. Amazonite is a type of microcline feldspar colored blue to green by small amounts of interstructural lead, and possibly affected by natural radiation over a long geological period. Previously, it was reported here to be the official state mineral of Colorado.

Talk:Cordite So accidents to WWI German ships don't imply that different variants of cordite have different safety margins - the German's did not use Cordite in WW I or WW II. The explosive charge in the shell, in contrast to the propellant charge that fires the shell up the barrel, is a high explosive.

Pegmatite Pegmatite containing lepidolite, tourmaline, and quartz from the White Elephant Mine in the Black Hills, South Dakota. A pegmatite is a holocrystalline, intrusive igneous rock composed of interlocking phaneritic crystals usually larger than 2.5 cm in size (1 inch); such rocks are referred to as pegmatitic. The word pegmatite derives from Homeric Greek, πήγνυμι (pegnymi), which means “to bind together”, in reference to the intertwined crystals of quartz and feldspar in the texture known as graphic granite.

Magnetite Magnetite is a mineral, one of the three common naturally occurring iron oxides (chemical formula Fe3O4) and a member of the spinel group. Magnetite is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of iron, and this was how ancient people first noticed the property of magnetism. Small grains of magnetite occur in almost all igneous and metamorphic rocks.

Stellite Stellite alloy is a range of cobalt-chromium alloys designed for wear resistance.It may also contain tungsten or molybdenum and a small but important amount of carbon.It is a trademarked name of the Kennametal Stellite Company and was invented by Elwood Haynes in the early 1900s as a substitute for cutlery that stained (or that had to be constantly cleaned).tellite alloys are so hard that they are very difficult to machine, and anything made from them is, as a result, very expensive. Typically, a Stellite part is precisely cast so that only minimal machining is necessary. Stellite is more often machined by grinding, rather than by cutting.

Andesite Andesite is the name used for a family of fine-grained, extrusive igneous rocks that are usually light to dark gray in color. They often weather to various shades of brown and these specimens must be broken for proper examination.ndesite is rich in plagioclase feldspar minerals and may contain biotite, pyroxene, or amphibole. Andesite usually does not contain quartz or olivine. Andesite is typically found in lava flows produced by stratovolcanoes.

THE MINERAL BENITOITE Benitoite is a somewhat obscure, but wonderful gemstone mineral that was only discovered in the early 1900's. It has a sapphire blue color and was first thought to be a variety of sapphire. But x-ray studies showed that the crystal structure was unlike any mineral previously discovered. It is one of only a few minerals to crystallize in the bar 6 m 2 class called the ditrigonal-dipyramidal symmetry class.
