The term hard water is usually used to describe water which has a relatively large amount of mineral content dissolved in it. If you are asking about solidified water, then that is always referred to as ice. You can do lots of things with water, for example you can add Gelatin to it and make jello, but if it's just water, and it has solidified, then that is called ice, and nothing else.
hard water
is it fluoride

a solid is an object that is hard and liquid is something you can pour
The most common constituents that make water hard are magnesium and calcium ions, since these form only very slightly soluble salts with anions in soap. The other alkaline earth metal cations have the same effect, but occur less commonly.
Oxygen is not always in the form of a gas. It can be found in liquid form as a component of the compound called water. It can be found in solid form as a component of rust (iron oxide) and many other compounds.Free oxygen is found as a gas on the planet earth because the temperate of the planet's surface and atmosphere are well above the boiling point of molecular oxygen, which is -297 F or -183 C. We use oxygen in liquid form as part of the fuel of some rockets. Then we have to work very hard to condense it out of the air.
hard water
A sample of water is said to be hard when it does not form lather readily with soap.
is it fluoride
Hard water does not produce lather. So soap does not work effectively with hard water as soap does not form a good lather with hard water.
YES, it's is the calcium that makes the water "hard". That is why you use a cleaner that has a calcium remover in it to get those hard water stains off.
Calcium.

in experince, i have never came accross hard water, but if it helps it goes relativly hard when it is in ice form. :)
yorkshire!

Hard water contains carbonates and bicarbonates of calcium and Magnesium.
