Quartzite was most frequently used when it was locally abundant and superior materials were rare or not available. The variety of colours displayed by quartzite are a consequence of minor amounts of impurities being incorporated with the quartz during … Plus, quartz is also the most prolific mineral you’ll find around the globe.
