I don't think bones are made of calcium. Calcium is a nutrition that your bones need to be strong.
it means that it is made of calcium

Two products made from calcium compounds are chalk (calcium carbonate) and cement (calcium oxide).
Hematite is not made from calcium carbonate.
Hair and nails are made primarily of calcium.
Calcium carbonate is the compound made from the elements oxygen, calcium, and carbon. It is commonly found in rocks, shells, and pearls.
they are made mainly from calcium and from a few other minerals.
Assuming you are asking, "Where was calcium refined/isolated," it was made in England. If you're asking what country it was made in, as in, where did calcium first exist, no country made calcium. It's an element created by nuclear fusion in stars, and so isn't and hasn't been made by countries.
They are made of a material calcium build-up and are not made of cells.or eggshell??? as it is not a man made object???
Calcium carbonate is made of the elements calcium, carbon, and oxygen.
The formula of the compound made by combining calcium with sulfur is CaS, which is known as calcium sulfide.
It is made up of carbon, oxygen and calcium. A carbonate contains oxygen and carbon so you know that, and then you can see that as it is called calcium carbonate it also contains calcium. :)
