Gas mantle in a street lamp (cold) Mantles in their unused flat-packed form. To produce a mantle, cotton is woven or knit into a net bag, impregnated with soluble nitrates of the chosen metals, and then transported to its destination. The user installs the mantle and then burns it to remove the cotton bag and convert the metal nitrates to ...
Earth's mantle is a layer of silicate rock between the crust and the outer core. It has a mass of 4.01 × 10 24 kg (8.84 × 10 24 lb) and makes up 67% of the mass of Earth. [ 1 ] It has a thickness of 2,900 kilometers (1,800 mi) [ 1 ] making up about 46% of Earth's radius and 84% of Earth's volume.
Subduction zone physics: Sinking of the oceanic lithosphere (sediments, crust, mantle), by the contrast of density between the cold and old lithosphere and the hot asthenospheric mantle wedge, is the strongest force (but not the only one) needed to drive plate motion and is the dominant mode of mantle convection. [citation needed]
The pressure at the bottom of the mantle is ≈140 GPa (1.4 Matm). [24] The mantle is composed of silicate rocks richer in iron and magnesium than the overlying crust. [25] Although solid, the mantle's extremely hot silicate material can flow over very long timescales. [26] Convection of the mantle propels the motion of the tectonic plates in the

Mantle, a black and white dog coat colour, especially in Great Danes; Mantle (mollusc), a layer of tissue in molluscs which secretes the shell
A mantle (from old French mantel, from mantellum, the Latin term for a cloak) is a type of loose garment usually worn over indoor clothing to serve the same purpose as an overcoat. Technically, the term describes a long, loose cape -like cloak worn from the 12th to the 16th century by both sexes, although by the 19th century, it was used to ...
Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. [1] [a] Flames, the most visible portion of the fire, are produced in the combustion reaction when the fuel reaches its ignition point.
A fire is contained in a firebox or fire pit; a chimney or other flue allows exhaust gas to escape. A fireplace may have the following: a foundation, a hearth, a firebox, a mantel , a chimney crane (used in kitchen and laundry fireplaces), a grate, a lintel , a lintel bar, an overmantel , a damper , a smoke chamber, a throat, a flue, and a ...
