provided the stimulus to synthesize some new chalcones using grindstone technique [25]. In grindstone technique, reaction occurs through generation of local heat by grinding of crystals of substrate and reagent by mortar and pestle. Reactions are initiated by grinding, with the small amount of energy through friction.

curvature. Although an outdated process, one generation technique that is still used today is loose abrasive grinding. This involves using various grit sizes mixed with water (this mixture is called a slurry) to remove glass. The larger the grit size, the more glass is removed, resulting in a faster removal rate. However, a rougher surface will be
