Quartz is a very common
mineral,
coming in many kinds, transparent and not. It is often in
crystals. Rose quartz is the name given to the soft pink
colour. Quartz crystals are used in
electronics because of special electrical properties that
they have. They are also used in special kinds of
microscopes. Quartz is also the main ingredient in
sand, which is used to manufacture glass, silica brick,
cement, and mortar. Ground quartz is used as an
abrasive
in stonecutting, sandblasting, and glass grinding. Powdered
quartz is used in making porcelain, scouring soaps,
sandpaper, and wood fillers. Rose quartz is very beautiful, and is
also used in jewelry such as the pendant to the
right.
