Proper placement is the first step in good care of Hibiscus. They are used as informal hedges or screens, foundation plants, or as a background for other garden plants. They do not do well as formal sheard hedges. It is better to use a single variety and color for mass planting than mixing, for appearance.
Feldspar is used as bonding agent along with magnesium oxide, magnesium chloride and other synthetic glue in the manufacture of abrasives, wheels, discs and other shapes. FELDSPAR comprises a group of minerals containing potassium, sodium, calcium and aluminium silicates.
The eight include the two feldspars plagioclase and orthoclase (potassium feldspar), quartz, the micas muscovite and biotite, the amphibole mineral hornblende, the pyroxene mineral augite, and the green mineral olivine.he feldspars are the most common mineral family in the crust of the Earth (about half of all minerals). This is a sample of potassium feldspar (orthoclase). Potassium feldspar (orthoclase) is often pinkish in color and displays the property of cleavage, the tendency to break along flat planes. It is harder than glass.
