Quartzite used for?

There is a difference between quartz and quartzite. Quartz is a pure mineral landing on 7 to 7.5 on the Mohs hardness scale, while quartzite is a formed rock that contains the mineral quartz and is thus no longer in pure mineral form. It is therefore also slightly softer than 7, depending on which other minerals it has formed rock with. Quartzite can be used as tomb stones as well as for gem purposes. Quartz has two properties that make it useful in science. Firstly, it is quite hard being a 7 on the Mohs hardness scale and secondly it has a high melting point so is often useful in experiments that require a "glass" to be heated to a very high temperature. An example of the latter is when a scientist needs a tube of "glass" to withstand a great amount of heat (such as a high temperature furnace for the introduction of a noble gas.) Quartz would be able to withstand a high heat in the founding of precious metals.
