PPT-B.Ball clay Ball clays are remarkable because of their high plasticity when mixed with

011 μm which is stabilized by a considerable content of the organic matter up to 2 wt Because of fine particles size the water demand for ball clays is higher than for most china clays The fine particle size also gives the ball clay bodies higher green strength and higher fired strength than other clays In the raw state ball clays range in color from light brown to nearly black depending on the organic content Ball clays . A Most Remarkable Man. A Most Remarkable Man. What is Clay?. Clay is a fine-grained natural rock . or soil . material that combines one or more clay minerals with traces of metal oxides and organic matter. . Our word “ceramic” comes from the Greek “. 2. nd. Annual Sporting Clays Classic. Sporting Clay Classic. Friday May 8. th. ,2015. Shane’s Clays Summerfield. Format. One round of Sporting Clays (8 different stations) $110 per person . 4 person Teams . Introduction. History. Pottery has been made by hand since prehistoric times.. Early uses were as functional vessels and figurative sculptures.. Clay was hardened. . by baking in the sun.. The discovery that fire hardened clay encouraged the development of more complex forms of pottery.. plasticity. !!. . Present. What is plasticity?. Plasticity. : When . an object receives an external force. ,. . it deforms. . Even if the external force is removed. Wedging. Working clay on a surface with the palms of the hands in order to remove air from it and obtain a uniform consistency. . Leather hard. The condition of unfired clay when most of the moisture has evaporated leaving it still soft enough to be carved into or joined to other pieces. . 3 Properties that make up clay. 1. Plasticity (ability to form). 2. Porosity (ability to hold moisture). *Similar to a sponge. 3. Vitrify (ability to harden and keep its shape). 3 types of clay. Clay is characterized by it’s iron content (color), vitrification process, and firing temperature..
