feldspar gross production in 2014 was 497kt, which represented an increase of 41% over the previous year. The State of Paraná was responsible for 40.5% of the gross production,
The idea to substitute feldspar in ceramic tile bodies by non-conventional fluxes goes back at least to the 1970s. Nevertheless, a detailed review of these attempts goes beyond the scope of this paper. Thus, only feldspar substitutes that actually went on production are here considered. They can be reconducted to the four sources in Table 3.
The evolution of the global production highlights a continuous growth over time (Fig. 7A) but for some strong fluctuations occurred in the last decade, most in charge of albitite suppliers (Fig. 7B).
The name feldspar encompasses a wide range of related minerals. Collectively, they are the most abundant group of minerals in the world, forming about 60 percent of the earth's crust. Feldspars are particularly abundant in igneous rocks like granite. Most often, commercial feldspar is mined from pegmatite or feldspathic sand deposits.

Feldspar . was produced by six companies in California, Idaho, North Carolina, and ia. ... 30 States and to foreign destinations, including Canada and Mexico. In pottery and glass, feldspar and nepheline syenite function as a flux. Glass manufacturing accounted for an ...
Orthoclase Feldspar: Represented by the formula KAlSi 3 O 8, Orthoclase is the potassium feldspar member of the group. This is a common raw material for the manufacture of some glasses and ceramics. Plagioclase Feldspar: Comprised of a solid solution series from calcium to sodium (Ca,Na)AlSi 3 O 8. The variety within this type is significant ...
