what is quartz made of
1 The mineral of which quartz is made is called silica, with the above composition SiO2. 2  I hope I was able to give some hints as to what quartz is and how it can be further divided into two subgroups based on its visible or invisible crystal structure (macro ... and 3  ... micro... ).o if you have looked for a simple straightforward answer, here it is: Quartz is made of Silicon Si and oxygen O. But not everything is so simple... Follow on... I would like to make a digression here, but at the end we will have, I hope, better knowledge about what quartz is.
