A shell casing is a piece of ammunition that is made of metal. It is often brass, but it can be made of other metals as well, and the more durable the better. Shell casings can be made from any kind of ammunition that is fired from a pistol, rifle or shotgun. It is not a bullet, but it is a piece of the larger ammunition mechanism that is loaded into the chamber to be shot.
Container glass is manufactured by combining quantities of minerals (and usually glass cullet) to obtain a feedstock rich in silica (SiO 2), soda (Na 2 O) and lime (CaO). Whilst a wide range of minerals can be used, the most common ingredients are high purity silica sand, soda ash (Na 2 CO 3) and limestone (CaCO 3).
