Clay is a naturally occurring material composed primarily of fine-grained minerals, which show plasticity through a variable range of water content, and which can be hardened when dried and/or fired. Clay deposits are mostly composed of clay minerals ( phyllosilicate minerals), minerals which impart plasticity and harden when fired and/or dried, and variable amounts of water trapped in the mineral structure by polar attraction. Organic materials which do not impart plasticity may also be a part of clay deposits. [1]Clay minerals are typically formed over long periods of time by the gradual chemical weathering of rocks, usually silicate-bearing, by low concentrations of carbonic acid and other diluted solvents. These solvents, usually acidic, migrate through the weathering rock after leaching through upper weathered layers. In addition to the weathering process, some clay minerals are formed by hydrothermal activity. Clay deposits may be formed in place as residual deposits, but thick deposits usually are formed as the result of a secondary sedimentary deposition process after they have been eroded and transported from their original location of formation. Clay deposits are typically associated with very low energy depositional environments such as large lake and marine deposits. Primary clays, also known as kaolins, are located at the site of formation. Secondary clay deposits have been moved by erosion and water from their primary location[2]. Clays are distinguished from other fine-grained soils by differences in size and/or mineralogy. Silts, which are fine-grained soils which do not include clay minerals, tend to have larger particle sizes than clays, but there is some overlap in both particle size and other physical properties, and there are many naturally occurring deposits which include both silts and clays. The distinction between silt and clay varies by discipline. Geologists and soil scientists usually consider the separation to occur at a particle size of 2 µm (clays being finer than silts), sedimentologists often use 4-5 μm, and colloid chemists use 1 μm.[1] Geotechnical engineers distinguish between silts and clays based on the plasticity properties of the soil, as measured by the soils' Atterberg Limits. ISO 14688 grades clay particles as being smaller than 2 μm and silts larger.

1. Grog!
November 20, 2009
I watched her skillful hands do the seemingly impossible. From a cold, moist lump of clay emerged a beautiful and functional piece of art. The whir of her potter's wheel lulled me as I watched her clay-covered hands cooperate with the spinning wheel to create the formless lump into an exquisite bowl. From the wheel to the drying rack to the kiln to the art show or sales shelf - the process never ceased to amaze me. But what shocked and surprised me even more was what she did with the inevitable broken or damaged piece.
I have marveled for years at the creative expression within such art... (read more)

He didn’t know which was better – eating his grandmothers’ spicy, flavorful meals and their handmade tortillas, or listening to their colorful stories. Both fed, nurtured and satisfied him.
