Orthoclase is the most common potassium feldspar, forming the majority of potassium feldspar found in felsic plutonic igneous rocks, some high temperature veins, and higher-grade metamorphic rocks. Sanidine has a less ordered crystal structure than orthoclase and is primarily found in volcanic igneous rocks where magmas cooled more rapidly and ...

In glassmaking, feldspar provides alumina for improving hardness, durability, and resistance to chemical corrosion. In ceramics, feldspar is used as a flux, lowering the vitrifying temperature of a ceramic body during firing and forming a glassy phase. Glass and ceramics continued to be the major end uses of feldspar.
Present mines worldwide are adequately meeting the need for raw feldspar. Hard-rock mining for feldspars is done by open-pit methods, either by the mine owner or by contractors. After the feldspar ore is drilled and blasted, secondary breakage is performed with a conventional drop ball. Ore is then loaded with a hydraulic shovel onto trucks and ...
Feldspar, a mineral that is the primary ingredient in pottery glaze, was mined extensively in Georgetown and the vicinity. Quarry workers took a break in the Consolidated (Goldings) quarry on the Bay Point Road in the early 1930s. Feldspar was loaded on barges at a tidal wharf and shipped to Trenton, New Jersey, or loaded on ships in Bath, Maine, for longer …
