What is Plagioclase? Plagioclase is the name of a group of feldspar minerals that form a solid solution series ranging from pure albite, Na(AlSi 3 O 8), to pure anorthite, Ca(Al 2 Si 2 O 8).Minerals in this series are a homogenous mixture of albite and anorthite. The names of the minerals in the series are arbitrarily given based upon their relative abundance of albite and …

The article focuses on feldspar, a mineral that composes of potassium, sodium, or a fusion of the two, and its various applications. According to estimates by scientists, the mineral is present at 60 percent of the crust of Earth, wherein it is commonly used for making glass and ceramics. Global mining of feldspar was about 20 million metric tons in 2010, wherein Italy, Turkey, and China …
The important feldspar end members are albite (NaAlSi 3 O 8), anorthite (CaAl 2 Si 2 O 8), and orthoclase (KAlSi 3 O 8). In Figure 6.34, the blue region shows the compositions of naturally occurring feldspars. Natural feldspars form two distinct series, the alkali feldspar series and plagioclase, both labeled on this triangular diagram. Alkali ...
Start by making the dressing. Whisk together the olive oil, Greek yogurt, lemon juice, mustard, honey, garlic, salt, and several grinds of pepper in a large bowl. Next, add the other ingredients. Toss in the small cauliflower florets, hard-boiled eggs, celery, pickled onions, capers, and fresh herbs. Mix well to coat in the dressing.
dressings should be selected based on the depth and exudate level of the wound, with frequent monitoring to ensure proper drainage and adherence. Alginate Dressings. Alginate dressings are derived from seaweed and contain calcium and sodium ions that form a gel-like substance when in contact with wound exudate.

Feldspar enhances the plasticity and workability of clay. It also lowers the firing temperature of the clay body, reducing energy consumption and preventing excessive shrinkage during firing. Feldspar contributes to the color and texture of the final ceramic piece. Depending on the type used, it can lend colors such as white, pink, beige, or gray.

Feldspars are also common in metamorphic rocks. As such, feldspar is an important (usually subordinate) component of most terrigenous clastics, reflected in its inclusion in QFL classification schemes. The two major groups of feldspar are potassium feldspars and plagioclases. All have low relief in plain polarized light (similar to quartz).
