Raw Materials and Processing

Now that we know what to look for in materials for structural clay products, the next step is to locate proper deposits and to win them in the best possible way. A knowledge of the science of geology is extremely helpful here because the application of geological principles changes the search from a needle-in-a haystack approach to predicting where satisfactory materials might be found. Geological maps are available from state and federal governments for large areas of the United States. Such maps may be bedrock maps which are especially helpful in locating shale deposits or they may be soil maps that indicate the presence of clay deposits. Where these maps are available, they should be used as a guide for exploration, but if they are not available the next best aids are topographic maps which are available for the whole country from the federal government. Some of the large structural clay products companies have a geologist who is assigned to find deposits, maintain adequate reserves, and oversee the mining operations. Other companies should hire a consulting geologist who is familar with the area to assist in exploration.
