A new technical bulletin about quartzite has been added to MIA+BSI’s Natural Stone Resource Library. The bulletin, written by geologist and educator Karin Kirk, covers properties of quartzite, understanding the difference between quartzite and other stones, and basic diagnostic tests that can be used to determine whether or not a stone is a genuine quartzite.

“The seemingly endless variety of available stone products is what makes our industry so interesting, yet unfortunately, equally confusing,” said Chuck Muehlbauer, MIA+BSI technical director. “The formation, composition, and properties of quartzite are frequently misunderstood, to the extent that inaccurate identification and marketing of these products are common. This bulletin efficiently addresses that confusion, and provides beneficial clarification to both the stone professional and consumer.”
