Structure: The PACIFICBLUE is a light blue extremely compact quartzite. Due to different concentrations of the mineral dumortierit (aluminum-boron-silicate) develops a wavy, streaky or maybe cloudy structure, which constitute one of the most beautiful rocks of the world. The chromatic spectrum reaches of white-blue up to a full azure and nearly always arises in different variations in a block. The sampling of PACIFICBLUE is quite difficult because of the strongly changing texture. Usually prototypes are not sufficient in order to obtain a general impression of the rock. Thus a wide sampling to the switching of an impression and the effect of the rock is recommended.

Characteristics: After the MOHS´ hardness scale (1 = chalk, 10 = diamond) the PACIFICBLUE possesses a degree of hardness from 6 to 7 and ranks thus among the hard rocks. It is to a large extent frost and polish-steadily. Quartzites are to be protected from acids.

 

Emergence: The PACIFICBLUE belongs as quartzite to the family of the metamorphic rocks. All rocks of this group developed under partly very high pressures and temperatures for a very long time. As a result the origin rock changed more or less strongly materially and structurally. In this case a quartz-rich sandstone with a small portion cleyey was partially melted. Causes for the rock transformation were the enormous forces, which arose during the collision of the continents and led to unfolding of high mountains.

Age: Approx. 2 billion years (Precambrian).

Use: Interior and external architecture; mainly for bathrooms (mirror-image moved), table- and kitchen plates, floor mats etc.
