What are the Outdoor porcelain OCS BASALTINO?
Outdoor porcelain OCS BASALTINO:
The word “quartz” is derived from the German word “Quarz” and its Middle High German ancestor “twarc”, which probably originated in Slavic, cf. Czech tvrdý (“hard”), Polish twardy (“hard”), Serbian and Croatian tvrd (“hard”).
The Ancient Greeks referred to quartz as κρύσταλλος (krustallos) derived from the Ancient Greek κρύος (kruos) meaning “icy cold”, because some philosophers (including Theophrastus) apparently believed the mineral to be a form of supercooled ice. Today, the term rock crystal is sometimes used as an alternative name for the purest form of quartz.
