What Is the Difference Between Quartz and White Feldspar ...

Feldspar grows (when allowed to) into rectangular crystals, and then usually breaks the same way. This breakage pattern is called cleavage, and feldspar has two directions of cleavage that meet at close to a 90 degree angle (just like a stairway). If you see little sparkles when you look at the rock, the flashes may be the light reflecting off the mirror-like cleavage surfaces.

How Can I Tell the Difference Between Fluorite & Quartz ...

Feldspar Distinctions, Characteristics & Identification

Alkali feldspar (also called potassium feldspar or K-feldspar) has a color range from white to brick-red, and it's typically opaque. Many rocks have both feldspars, like granite. Cases like that are helpful for learning to tell the feldspars apart. The differences can be subtle and confusing. That's because the chemical formulas for the feldspars blend smoothly into each other.

Dolomite, wollastonite and calcite were chosen as different CaO sources. Feldspar was used to obtain dense porcelain body at a relatively low temperature. The high content of CaO decreases the liquid phase viscosity of the porcelain at high temperatures, which makes it particularly easy to generate shape distortion of the porcelain bodies. To resist high-temperature deformation, a small amount ...
