The rock here is a porphyritic granite (porhyritic meaning that the stone has large-grained crystals, such as feldspar or quartz, dispersed in a fine-grained feldspathic matrix or groundmass). ❋ Greygirlbeast (2010)
And as far as craftsmanship, depending on which cosmetic dentist you go to, he or she will work with porcelain veneers fabricated by a machine out of Lucite, or porcelain veneers handcrafted out of feldspathic porcelain by a master artist (yes, I call the people who do this type of work artists.) ❋ Unknown (2010)
The composition is what we ceramic engineers call Âfeldspathic. ❋ Unknown (2009)
The Northern Inner Piedmont (45e) is characteristically underlain by highly deformed and deeply weathered Cambrian and Proterozoic feldspathic gneiss, schist, and melange. ❋ Unknown (2008)
Between the heavy clays and blue mud of the mangrove swamps and the granite and sandstone of the mountain ranges, the undulating rises are mainly composed of red clay, sandstones, shales, and granitic and feldspathic rocks, with extensive deposits of laterite in red clays on the surface. ❋ Isabella Lucy (2004)
Its mineralogical constitution is not simple; in some parts the rock is of a cherty, in others of a feldspathic nature, including thin veins of serpentine. ❋ Unknown (2003)
Near the coast the rough lava is quite bare: in the central and higher parts feldspathic rocks by their decomposition have produced ❋ Unknown (2003)
The first true porcelain with high-fired feldspathic glaze probably dates from about this time. ❋ Unknown (2001)
Sienite and feldspar succeeded in our descent to the snow line, where we found a feldspathic granite. ❋ De Witt C. Peters (N/A)
English bone porcelains are very beautiful, and though they are not genuine feldspathic products they are highly esteemed and in demand everywhere. ❋ Sara Ware Bassett (1920)
Near the coast the rough lava is quite bare: in the central and higher parts, feldspathic rocks by their decomposition have produced a clayey soil, which, where not covered by vegetation, is stained in broad bands of many bright colours. ❋ Unknown (1909)
Of this structure, called FOLIATION, we may distinguish two types, -- a coarser feldspathic type, and a fine type in which other minerals than feldspar predominate. ❋ William Harmon Norton (1900)
Considering the large amount of feldspathic material in these rocks, do you infer that they were derived from the adjacent crystalline and metamorphic rocks of the oldland of Appalachia, or from the sedimentary Paleozoic rocks which had been folded into mountains during the Appalachian deformation? ❋ William Harmon Norton (1900)
The Triassic rocks are mainly red sandstones, -- often feldspathic, or arkose, with some conglomerates and shales. ❋ William Harmon Norton (1900)
At various places in the older rocks of middle and western North Carolina are to be found extensive veins or dikes composed largely of feldspathic material which has decayed from the action of atmospheric agencies, and which decayed material is generally designated as Kaolin. ❋ North Carolina. Board Of Agriculture. (1896)
In Wilson county, a few miles south of Wilson, on the Wilmington and Weldon railroad, and on Moccasin river, are considerable beds of coarse, red, feldspathic granite, which splits readily, takes a beautiful polish, and closely resembles the red Scotch granite. ❋ North Carolina. Board Of Agriculture. (1896)
It occurs in the various feldspars and feldspathic rocks, and in mica. ❋ Unknown (1895)
