Calcium citrate malate is a well-absorbed form of calcium found in some fortified juices . Calcium supplements contain varying amounts of elemental calcium. For example, calcium carbonate is 40% calcium by weight, whereas calcium citrate is 21% calcium.
HISTORY: Tin is one of the oldest metals known by man. There are domestic utensils and arms made of brass (copper with about 15% of tin), dating from 3500 B.C.. The Phoenicians had a very important role in the spread of brass utensils due to its commercial trades with Britain, Spain and the Middle East.
Calcium (Ca) and water - Lenntech
Calcium is a determinant of water hardness, because it can be found in water as Ca 2+ ions. Magnesium is the other hardness determinant. Calcium is present in various construction materials, such as cement, brick lime and concrete.

Eventually with enough soap, a lather does form, when all the calcium and magnesium ions have been precipitated as a ''scum salt''! However, it does mean a lot of soap is wasted! The amount of hardness in water sample can be estimated by titrating it with soap solution and noting what volume of soap solution is needed to produce a lather.

Periodic Table of Elements: Calcium - Ca …
Calcium is the fifth most abundant metalic element in the earth''s crust, but is never found in the elemental form because it is so reactive. It is found in limestone (CaCO 3) gypsum (CaSO 4. 2H 2 O) and fluorite (CaF 2). Pure calcium is a shiny soft metal that will
Lunar Geology: Minerals on the Moon - PERMANENT
Calcium oxides and calcium silies are not only useful for ceramics, but pure calcium metal is an excellent electrical conductor. Calcium metal is not used as a conductor on Earth simply because calcium burns spontaneously when it comes in contact with oxygen (much like the pure magnesium metal in camera flashbulbs).

Definition of Calcium - MedicineNet
Calcium: A mineral found mainly in the hard part of bones, where it is stored. Calcium is added to bone by cells called osteoblasts and removed from bone by cells called osteoclasts. Calcium is essential for healthy bones and is also important for muscle contraction, heart action, and normal blood clotting.
Calcium: The mineralogy of Calcium locality database. This is based on the nuer of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock-forming-minerals so it does not give an undistorted distribution of Calcium mineral species.
