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 main reasons that sodium feldspar is used in this application is due to the alumina content and the minerals ability to act as a flux.The alumina content of sodium feldspar is over 19%; this provides the glass with impact and thermal shock resistance.eldspar is the mineral name given to a group of minerals distinguished by the presence of aluminum (Al) and the silica (SiO 4) in their chemistry. They form in a variety of thermal environments, during the crystallization of liquid rock (magma), by metamorphism of rocks deep in the earth, and in sedimentary processes.
