Feldspar is a common raw material in the production of ceramics and geopolymers. ... Feldspar does not have a strict melting point, since it melts gradually over a range of temperatures. This greatly facilitates the melting of quartz and clays and, through appropriate mixing, allows modulations of this important step of ceramic making.
· Regarding the raw material composition, porcelain stoneware paste consists of a mixture of ball clays (sometimes kaolin), quartz and feldspars ().The clay fraction favours forming operation since it allows plasticity to the green piece and it also provides the sufficient mechanical strength to withstand the stresses before firing.
Feldspar is an important ingredient in the manufacture of glass and an important raw material as well, because it acts as a fluxing agent, reducing the melting temperature of quartz and helping to control the viscosity of glass. The alkali content in feldspar acts as flux, lowering the glass batch melting temperature and thus reducing production costs. Ceramics. In the manufacture of ceramics ...

Melting Points of Rocks Igneous rocks form through the crystallization of is a considerable range of melting temperatures for different compositions of magma. All the silies are molten at about 1200°C (when a part of rock) and all are solid when cooled to about 600°C. Often the silies are grouped as high, medium and lowmelting point solids.

Feldspar Group Minerals. Feldspar is the name of a large organization of rockforming silie minerals that make up over 50% of Earth's crust. They are discovered in igneous, metamorphic, and sedimentary rocks in all components of the sector. Feldspar minerals have very comparable structures, chemical compositions, and bodily properties.
