Gypsum

Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO₄·2H₂O. It is widely mined and is used as a fertilizer, and as the main constituent in many forms of plaster, blackboard chalk and wallboard. A massive fine-grained white or lightly tinted variety of gypsum, called alabaster, has been used for sculpture by many cultures including Ancient Egypt, Mesopotamia, Ancient Rome, Byzantine empire and the Nottingham alabasters of medieval England. It is the definition of a hardness of 2 on the Mohs scale of mineral hardness. It forms as an evaporite mineral and as a hydration product of anhydrite.

Etymology and history

The word gypsum is derived from the Greek word γύψος (gypsos), "chalk" or "plaster". Because the quarries of the Montmartre district of Paris have long furnished burnt gypsum (calcined gypsum) used for various purposes, this dehydrated gypsum became known as plaster of Paris. Upon addition of water, after a few tens of minutes plaster of Paris becomes regular gypsum (dihydrate) again, causing the material to harden or "set" in ways that are useful for casting and construction.

Lime (material)

Lime is a calcium-containing inorganic material in which carbonates, oxides and hydroxides predominate. Strictly speaking, lime is calcium oxide or calcium hydroxide. It is also the name of the natural mineral (native lime) CaO which occurs as a product of coal seam fires and in altered limestone xenoliths in volcanic ejecta. The word "lime" originates with its earliest use as building mortar and has the sense of "sticking or adhering."

These materials are still used in large quantities as building and engineering materials (including limestone products, concrete and mortar) and as chemical feedstocks, and sugar refining, among other uses. Lime industries and the use of many of the resulting products date from prehistoric periods in both the Old World and the New World. Lime is used extensively for waste water treatment with ferrous sulfate.

The rocks and minerals from which these materials are derived, typically limestone or chalk, are composed primarily of calcium carbonate. They may be cut, crushed or pulverized and chemically altered. "Burning" (calcination) converts them into the highly caustic material "quicklime" (calcium oxide, CaO) and, through subsequent addition of water, into the less caustic (but still strongly alkaline) "slaked lime" or "hydrated lime" (calcium hydroxide, Ca(OH)₂), the process of which is called "slaking of lime".

Saber Marionette J

Saber Marionette J (セイバーマリオネットJ, Seibā Marionetto Jei) is a Japanese anime produced by Hal Film Maker, aired on TV Tokyo from October 1, 1996 to March 25, 1997. It is the second installation of the Saber Marionette line of series, preceding Saber Marionette J Again and succeeding Saber Marionette R. The show was localized in North America by Ocean Productions and into six other languages by various companies.

In between production, Saber Marionette J made transitions in other media. A manga serialized in the Kadokawa Shoten magazine Dragon Age was circulated from October 1996 to November 1999, collected into five volumes by the company. A concurrent radio drama was broadcast and the show's original soundtrack was published by Kings Records. The show was also the basis for a PlayStation fighting game called Saber Marionette J: Battle Sabers, developed and published by Tom Create.
