The meaning behind the joke becomes clear, though, when you look up magnesium iron silicate hyrdroxide’s more common name. As it turns out, the mineral is commonly known as Cummingtonite, which is admittedly a truly hilarious name.
Insoluble in water and most organic solvents. The naturally-occurring form of magnesium silicate hydroxide is called talc, a soft mineral that feels waxy and soapy to the touch. This characteristic has led to another name for the mineral: soapstone.
Rarely as distinct crystals. Columnar to fibrous and granular Translucent, will transmit light on thin edges. Characterized by light brown color and needlelike, often radiating habit. Difficult to distinguish from anthophyllite or gedrite without optical and/or X-ray tests. 2, magnesium iron silicate hydroxide.
Magnesium silicate is widely used to remove free fatty acids and other polar compounds from used cooking oils to extend their life. It can also be used to purify biodiesel by adsorbing free glycerin, soaps, methanol as well as monoglycerides and sterol glucosides.
What is magnesium silicate hydroxide?
Magnesium silicate hydroxide (mag-NEE-zee-um SILL-uhkate hye-DROK-side) is also known as hydrated magnesium silicate, hydrous magnesium silicate, magnesium silicate hydrous, talc, talcum, and soapstone. It belongs to a large family of magnesium silicates that occur in nature. Magnesium silicates contain at least one magnesium ion and one or more silicate (SiO 3) ions, and often contain one or more molecules of water of hydration. Other members of the family include magnesium metasilicate (MgSiO 3 ), magnesium orthosilicate (Mg 2 SiO 4 ), magnesium trisilicate (Mg 2 Si 3 O 8 ), and magnesium trisilicate pentahydrate (Mg 2 Si 3 O 8 ·5H 2 O).
Talc’s chemical formula differs somewhat from that of magnesium silicate hydroxide: Mg 3 Si 4 O 10 (OH) 2.
Talc is one of the softest minerals known. It has a numerical rank of 1 on the Mohs scale of minerals. The Mohs scale ranks minerals from the softest (1 = talc) to the hardest (10 = diamond). Talc is so soft that it can be scratched with the fingernail.
The magnesium silicates are obtained from natural sources, such as talc (magnesium silicate hydroxide), en statite (magnesium metasilicate), forsterite (magnesium orthosilicate), meerschaum (magnesium trisilicate), or serpentine (Mg 3 Si 2 O 7 ). In all cases, extraction of the desired compound involves a number of steps in which …
The magnesium silicates contain three of the eight most abundant elements in Earth’s crust: oxygen (the most abundant element), silicon (the second most abundant element), and magnesium (the eighth most abundant element).
It belongs to a large family of magnesium silicates that occur in nature.

As a non-caking agent in animal feeds and fertilizers. Magnesium silicate hydroxide and other forms of magnesium silicates have a number of industrial applications, including: As an odor absorbent. Exposure to talc dust may cause irritation of the skin, respiratory system, and, especially, the eyes.
