Fire Clay & Ceramic ClayThe Cedar Heights Clay Company has been mining and processing clays in Southern Ohio from the Oak Hill Operations since 1924. The refractory clays at Resco offer a veritable palette of colors and textures for every firing method in use today. Our well-known locally mined clays includes RedArt Clay©, GoldArt Clay©, Roseville Stoneware Clay©, Salt Lick Stoneware Clay©, Ceramic Fireclay, and Industrial Fireclay.
RedArt is a red burning sedimentary clay with a firing range of cone 04 to cone 4 when used as the primary clay body component. RedArt clay offers excellent plasticity straight out of the bag and can be used as 100% of a red burning earthenware body. Small additions (10-15%) of ball clay or GoldArt will enhance the plasticity for work on the wheel without sacrificing plasticity.
GoldArt is a stoneware clay burning to a very light buff color at cone 06 and to a darker cream color at cone 8 and light grey at cone 10. Used as a primary component of stoneware bodies in the cone 6-10 range, it lends plasticity to the body while the small amount of iron and titania lead to pleasing orange, grey, red and other color effects in reduction and/or wood firing atmospheres.
Salt Lick Stoneware Clay
Salt Lick Stoneware has many of the same properties as GoldArt but has lower alumina and higher potassia which helps lower the maturing temperature without sacrificing plasticity. Roseville Stoneware Clay burns to a darker cream color than either GoldArt or Salt Lick and matures at cone 6-8. Excellent as the primary component of salt and soda fired bodies.
Cedar Heights Clays are available from a distributor near you. All refractory clays are available as 200 mesh in 50-pound bags. In addition to bags of clay for sale, bulk packaging is also available.
Our Hillsborough deposit located in the “Piedmont” of North Carolina has been producing consistent ore since it opened in 1958. A unique mix of the mineral andalusite and massive grain pyrophyllite increases the heat resistance of the natural combination raising the melting point. The purity of this pyrophyllite ore makes it an excellent source for alumina and silica in high temperature formulations. Piedmont Minerals has been a staple raw material producer in refractory mixes and many other ceramic applications. Our product is shipped by bag, super sack, pneumatic tanker truck, and railcar.
Classification and blending at Cedar Heights Clay and Piedmont Minerals allow for versatile chemical and mineralogical classes of products. Our selection of refractory clays and minerals contain Alkatrol©, Andafrac©, Pyrofrac©, Pyrophyl©, Pyrotrol©. Our Andalusite and Pyrophyllite clay offerings vary from refractories to aesthetic coatings while our unique mineral deposit provides numerous solutions to improve your products.
