The group is called silicates.
Theoretically yes, though any given sample of quartz may contain inclusions (non-quartz stuff trapped inside) making it heterogeneous.
The basic idea is that glass is made out of heated sand, which is silicon dioxide and the key part of that is the silicon.Chemicals for making common glass are Silica (silicon dioxide, the glassy part), and Sodium Carbonate (Soda Ash), lowers the melting point.
The acid tells you wether or not te mineral contains lime. Drip any (strong) acid onto the mineral, and if it starts bubbling, the mineral contains lime. It's often used by people who have a fishtank, as rocks which contain lime are bad for most freshwater fish.
Well porcelain is made from a very fine white clay called china clay or kaolinite. 1400°C is used when firing it. However, many modern ceramic materials are not made from clay, instead they are produced from silicon and zirconium compounds, zirconia (ZrO ) or silicon nitride (Si3N4)I really hope that helps ;)
Obsidian cools so quickly the mineral grains do not have time to form.
Other elements

Most likely not. Silicate minerals contain silicon in combination with oxygen. However, silicon itself is considered a non-silicate mineral, composed entirely of the element silicon; without the oxygen, however, it IS a non-silicate mineral.
It must contain silicon and oxygen.. Sammantha G.

Silicate Mineral
Halides - contain halogens (group 17 of the periodic table) Sulfides - contain sulfer Carbonates - contain carbon, oxygen, and one other element Silicates - contain silicon and oxygen Oxides - contain oxygen and one other element Native elements - are pure elements There are others but these are the 6 major groups.
Silicates Minerals. Eg. Quartz (SiO2).
Silicate is literally Silicon and Oxygen. To be a silicate, therefore, a mineral must contain SiO2. The classic Silicate is Quartz, which is pure SiO2.
The two elements that must be present in a silicate are silicon and oxygen.
Nonsilicate minerals, like Galena (formula: PbS)
