In both examples quartz-based tempers were used by the ancient potters, either in the form of sand or of earth rich in quartz. The central aim of the present study is the clarification of the effect of quartz temper on the physical and mechanical properties of clay ceramics and the elucidation of the underlying.Sand is a common material found on beaches, deserts, stream banks, and other landscapes worldwide. In the mind of most people, sand is a white or tan, fine-grained, granular material. However, sand is much diverse - even beyond the pink sand beaches of Bermuda or the black sand beaches of Hawaii. These are just a few of the many types of sand.

Quartz sand, calcite, iron oxides, organic materials, and other impuri-ties. They can exhibit wide ranges of plasticity and color, depending on mineralogy, amounts of impurities, and degree of weathering (Figure 1). Common clays occur in most counties north of Lake Okeechobee (Bishop and Dee, 1961). Escambia and Santa Rosa counties, and the St.Quartz crystals have piezoelectric properties they develop an electric potential upon the application of mechanical stress. An early use of this property of quartz crystals was in phonograph pickups. One of the most common piezoelectric uses of quartz today is as a crystal oscillator. The quartz clock is a familiar device using the mineral.
