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.
All of the feldspar minerals exhibit a blocky crystal habit, hardness greater than glass, and two directions of cleavage that meet at nearly right angles. Together with their non-metallic luster and typically opaque character, these properties will usually distinguish feldspars from other common non-metallic minerals.
