Solid is divided into crystalline and non-crystalline. Such as ice, quartz, mica, salt, alum Crystal, glass, rubber, rosin, asphalt, candles, etc. are non-crystalline.1 Crystals have a natural, regular geometry, and no crystals are atoms, and ions or molecules are arranged in space at regular intervals, Form in the crystallization process
