Calcium ( from Latin, genitive calcis, meaning " lime ") was known as early as the first century when the Ancient Romans prepared lime as calcium oxide.

Calcium metal was not available in large scale until the beginning of the 20th century.

* Calcium cyclamate ( Ca ( C < sub > 6 </ sub > H < sub > 11 </ sub > NHSO < sub > 3 </ sub >)< sub > 2 </ sub >) was used as a sweetening agent but is no longer permitted for use because of suspected cancer-causing properties.

In 2005, Calcium Made Interesting: Sketches, Letters, Essays & Gondolas was published.

Calcium oxide, in the form of lime, was often used for this purpose, since it could react with the carbon dioxide and sulfur dioxide produced during roasting and smelting to keep them out of the working environment.

Calcium was needed for agricultural, pharmaceutical and paint products.

In 1956, Thompson-Weinman expanded its own crushing operation in Sylacauga ; and Sylacauga Calcium Products was formed as a division of Moretti-Harrah.

The question that piqued his curiosity was that how come a heavier element like Calcium is present up to a greater height compared to a lighter element like Hydrogen, apparently defying gravity.

A semi-sequel, Calcium Made Interesting, was released in 2005.

Chodes was also a member of Vince Mole and his Calcium Orchestra, headed by former Apples in Stereo guitarist Chris Parfitt.

His first piece was Calcium Light Night set to music by Charles Ives and premiered in 1977.

Calcium is essential for living organisms, in particular in cell physiology, where movement of the calcium ion Ca < sup > 2 +</ sup > into and out of the cytoplasm functions as a signal for many cellular processes.

Calcium has four stable isotopes (< sup > 40 </ sup > Ca, < sup > 42 </ sup > Ca, < sup > 43 </ sup > Ca and < sup > 44 </ sup > Ca ), plus two more isotopes (< sup > 46 </ sup > Ca and < sup > 48 </ sup > Ca ) that have such long half-lives that for all practical purposes they also can be considered stable.

* Calcium carbide ( CaC < sub > 2 </ sub >) is used to make acetylene gas ( for use in acetylene torches for welding ) and in the manufacturing of plastics.

* Calcium chloride ( CaCl < sub > 2 </ sub >) is used in ice removal and dust control on dirt roads, in conditioner for concrete, as an additive in canned tomatoes, and to provide body for automobile tires.

* Calcium phosphate ( Ca < sub > 3 </ sub >( PO < sub > 4 </ sub >)< sub > 2 </ sub >) is used as a supplement for animal feed, fertilizer, in commercial production for dough and yeast products, in the manufacture of glass, and in dental products.

* Calcium levels in livestock feed are supplemented with it, such as for poultry ( when ground up ).

* Calcium, a common electrolyte, but also needed structurally ( for muscle and digestive system health, bone strength, some forms neutralize acidity, may help clear toxins, provides signaling ions for nerve and membrane functions )

Calcium channel blockers and losartan are associated with a lower risk of gout as compared to other medications for hypertension.

Calcium for egg development-another hypothesis-does not appear to be a reason for geophagy during this period as peak usage is after the hatching of eggs.

Calcium ( Ca ) is in group 2, for it contains 2 valence electrons.

Historic landmarks include the stone house at the intersection of State Route 342 and County Route 138 that once served as the post office for the area, and the Calcium Community Church at the same intersection.

Calcium is known to be a treatment for gastric problems, and gastric problems such as acid reflux are known to increase bruxism.

Calcium ions are required for each cycle of the sarcomere.

* Calcium hypochlorite ( Ca ( OCl )< sub > 2 </ sub >) is used as a swimming pool disinfectant, as a bleaching agent, as an ingredient in deodorant, and in algaecide and fungicide.

* Calcium permanganate ( Ca ( MnO < sub > 4 </ sub >)< sub > 2 </ sub >) is used in liquid rocket propellant, textile production, as a water sterilizing agent and in dental procedures.

Calcium carbide reacts with water to produce acetylene, which acts as an artificial ripening agent.

Calcium phosphate is used in baking as a raising agent, with E number E341.

Calcium silicate ( CaSiO < sub > 3 </ sub >), a commonly used anti-caking agent, added to e. g. table salt, absorbs both water and oil.

Calcium carbimide, sold as the citrate salt under the trade name Temposil, is an alcohol sensitizing agent.

Calcium provides an important link between tectonics, climate and the carbon cycle.

* Calcium hydroxide solution ( Ca ( OH )< sub > 2 </ sub >) ( also known as limewater ) is used to detect the presence of carbon dioxide by being bubbled through a solution.

Calcium carbonate dissolved into water may precipitate out where the water discharges some of its dissolved carbon dioxide.

Calcium carbonate is susceptible to even a weak acid solution because the crystals of calcium carbonate react with the acetic acid in the vinegar to form calcium acetate and carbon dioxide.

Calcium and carbon are added.

* Calcium carbonate ( Limestone or chalk ) decomposes into calcium oxide and carbon dioxide when heated:

Calcium phosphate ( phosphate rock ) is heated to 1, 200 – 1, 500 ° C with sand, which is mostly, and coke ( impure carbon ) to produce.
