  • Ceramic Clay Vocabulary List
    CERAMIC CLAY VOCABULARY LIST 1. Ceramics - Objects made of clay fired sufficiently high in temperature for a chemical change to take place in the clay body, usually over 1550 degrees F. FOUR CERAMIC CONSTRUCTION TECHNIQUES: 2. Coiled Pottery - One of the oldest ways of forming pottery. Long strands of clay which are laid on top of each other and joined through blending coil to coil. Coil pieces can be almost any shape or size. 3. Pinch Pots - Starting with a ball of clay the potter opens a hole into the ball and forms a bowl shape through a combination of stroking and pinching the clay. Many coil-built pieces are constructed on top of a pinched bottom. 4. Slab Built - Clay slabs are cut to shape and joined together using scoring and wet clay called slip. Slabs can be draped over or into forms, rolled around cylinders or built up into geometric forms. Large forms are difficult because of stresses on the seams and because the slab naturally sags. Some potters get around this by working fibers into the clay body. The fibers burn out during the firing, leaving a network of tiny holes. 5. Wheel thrown - The term throw comes from Old English meaning spin. A piece of clay is placed on a potter's wheel head which spins. The clay is shaped by compression while it is in motion. Often the potter will use several thrown shapes together to form one piece (a teapot can be constructed from three or four thrown forms). TYPES OF CLAY: 6. Earthenware - A low-fire clay.

  • General Condition Terms for Ceramics the Purpose of This Glossary Is To
    General Condition terms for Ceramics The purpose of this glossary is to provide you with a common language for the condition of ceramic items. Hardness the hardness of a ceramic is dependent on the type of clay used, its porosity and firing temperature. The following are simples classifications. Greenware Unfired clay articles. Earthenware- A glazed porous ceramic created by low temperature firing. Majolica or maiolica is tin glazed earthenware and overpainted with oxides developed in Majorca. Similar pottery is known in France as Faience and the UK as Deftware. Porcelain- Kaolin based ceramic body that has been fired between 1200oC- 1400°C vitrifying the composition becoming non porous Bisque-unglazed porcelain Flaws Flaws are defects, visible marks or inclusions made during the manufacturing process that should be included in the description. Damage Damage describes defects made through use, handling, cleaning or storage. Damage includes nicks, cracks, scratches, paint wear and crazing. Abrasion – Scuff marks or areas of concentrated scratches, generally caused by rubbing against another item over time. Accretions-build up or deposit of a foreign materials on a surface Efflorescence-white powdery or hard salt deposits that are located on the surface of the ceramic Spalling- loss from the separation of the ceramic layers due salts migrating through the body and glaze Flaking –lifting and separation of the glazing from the ceramic body without complete loss of the insecure area Light scratches - Scratches which do not score the surface of the item. Can be seen but not felt. Deep scratches - Scratches which score the surface of the item and can be felt with a fingernail.

With cutoff tool, cut clay into 1" square strips the size of a stick of butter. 2. Mold clay with hands into an oblong shape rounding off the square edges. 3. Place oblong shape on a flat surface and gently roll clay back and forth with the palm of hands to create a rounded coil. 4. Keep rolling coil until it is an even 1/2" thick in diameter from end to end. Note: Pushing too hard may flatten coil. If this happens, gently roll on flat area to reshape coil. Ideal coils are uniform in diameter. Small Coil Tray / Coil Pot Base 1. Score then paint slip on connecting edges of coil and tightly spiral clay into a circle so that no space or gaps appear between coils. 2. To make tray or base larger, add coils by placing one diagonal cut coil end next to another and wet with slip. When desired length is reached, cut remaining loose coil from the base. Tray Handles 1. Cut two identically sized coils to form handles; cut ends of coils diagonally. 2.

  • Visitor's Guide
    VISITOR’S GUIDE INTRODUCTION Ceramics have transformed the world. For thousands of years, hu- mans have shaped and fired clay into practical, social, artistic, and ideo- logical objects that can be found in almost every culture around the globe. Important social and scientific information imbedded in manufacturing techniques and decorative motifs of ceramics has been passed on for generations, exchanged between cultures, and has revolutionized people’s way of life. This exhibition highlights the Art Museum’s ceramic collection which spans six continents and six thousand years. Looking through the lens of cultural and technological influences and exchanges, this showcase seeks to reveal the depth and diversity of the collection and the power these wares possess in shaping our functional, social, and esthetic lives. The Potter’s Tale: Contextualizing 6,000 Years of Ceramics Mount Holyoke College Art Museum Curated by Aaron F. Miller, Assistant Curator of Visual and Material Culture Yingxi Lucy Gong, Art Museum Advisory Board Fellow This exhibition is made possible by the Susan Davenport Page 1931 and Margaret Davenport Page Fales 1929 Art Fund. Technology & Production As the fragmentary pieces in this case demonstrate, there are three primary types of ceramics: earthenware, stoneware, and porcelain. These categories differ based upon both the clay and the temperatures at which the vessels are fired in the kiln. Earthenware is fired at the lowest tempera- tures, and as a result, is the most porous and susceptible to cracking. The higher temperatures used for stoneware and porcelain also require specific varieties of clays and other minerals to allow the process of vitrification to occur, in which the silica in the clay becomes glass.
