Formed of Clay: (a short novel of ancient Egypt)


Secondary or sedimentary clay is formed of lighter sediment that is carried farther in water and deposited. This secondary clay, a mixture of sediment, is finer and lighter than primary clay. Varying additives give the clay different characteristics. Clay comes to a production potter in one of two forms—as a powder to which water must be added, or with water already added.

Large factories purchase the clays in huge quantities as dry materials, making up the clay batch as needed each day.

A stoneware teapot mode by Jonah Wedgwood and Co. This lovely, stout stoneware teapot is the work of Josiah Wedgwood and Co. Teapots and associated cups became very popular about the mids because of the development importance of the "tea" and its ceremony.

Thus, a mainstay of porters in the eighteenth century was the teapot and cup sets. Josiah Wedgwood was not content to simply supply pottery rather haphazardly. He knew there was a large market for high-quality, attractive pottery and he certainly would do his best to regularize the product and develop some new products people just had to have. He was one of the first potters to sell his wares in advance through orders, thus creating a sample or "stock" product.

Since his products had to be uniform, he developed glazes that would give consistent results and divided the work process into many different steps so that one worker would not have a tremendous impact on the finished product. Particularly important to Wedgwood was the work of the modeller and the artist, who made the prototype shapes and designs for Wedgwood.

Wedgwood discovered that these artists could provide designs for new pottery that looked antique, and these neo-classicol pieces were the mainstay of his business for many years. Glazes are made up of materials that fuse during the firing process making the pot vitreous or impervious to liquids. Ceramics engineers define vitreous as a pot that has a water absorption rate of less than 0.

Glazes must have three elements: Color is derived by adding a metallic oxide, including antimony yellows , copper green, turquoise, or red , cobalt black , chrome greens , iron, nickel, vanadium, etc. Glazes are generally purchased in dry form by production potters. The glazes are weighed and put into a ball mill with water.

The glaze is mixed within the ball mill and grinds the glaze to reduce the size of the natural particles within the glaze. The cake mixture is formed into plugs and ready for forming. Pottery factories include art directors whose job it is to conceive marketable goods for the pottery company. Generally the art director, working with marketers, develops or creates an idea of a new creation. Interestingly, many pottery companies are reproducing old forms popular decades ago such as brightly-colored Fiesta Ware so that new design is not necessary or desirable in all cases.

The art director then works with a clay modeler, who produces an original form of the creation to the art director's specifications. If the form is deemed a viable candidate for production, the mold maker makes a plaster master for the jiggering machine which essentially traces a master shape onto a production piece or a hollow into which clay is poured in order to form a production piece.

The kiln changes the glaze into a glass-like coating, which helps make the pot virtually impervious to liquid. Single-color production pottery requires only one firing with the new kilns and glazes. Many glazes require that the greenware be fired once and made into a bisque or dull white, hard body, then glazed and fired again; however, this is not necessary with some new production glazes.

All raw materials are checked against the company's established standards.

From Clay Tablets to Canon: The Story of the Formation of Scripture It is likely that early Israel was a largely illiterate group with little access to or inclination The process is difficult, yet the ancient Egyptians mastered it in such a way that. In the Ancient Near East, clay tablets (Akkadian ṭuppu(m) 𒁾) were used as a writing medium, Collections of these clay documents made up the very first archives. Early writing also began in Ancient Egypt using hieroglyphs. By the end of the 3rd Millennium BC, ( BC), even the "short story" was first.

Clays must contain the ingredients required by the product and ordered by the company. Glazes must be as pure as possible and are checked for correct shade, viscosity, gravity, etc. Kiln temperature must be carefully monitored with heat cones and thermocoupies, etc. And each human involved in production uses their eyes to monitor against inferior products. There are no harmful by-products resulting from the production of pottery. Clay scraps and imperfect pieces produced off the jiggering machine or from slip casting may be re-mixed and re-used.

Background

Glazes must be lead-free as required by the Food and Drug Administration FDA , and glazes are tested inhouse to assure the FDA that they contain neither cadmium nor lead. All glazes may be touched by the human hand are not harmful in raw state. The Pottery and Porcelain of the United States. The Big Book of Ceramics. Pottery and Porcelain Made How Volume 4 Pottery Pottery. This convention began when people developed agriculture and settled into permanent communities that were centered on increasingly large and organized trading marketplaces [4] These marketplaces traded sheep, grain, and bread loaves, recording the transactions with clay tokens.

These initially very small clay tokens were continually used all the way from the pre-historic Mesopotamia period, BC, to the start of the historic period around BC, when the use of writing for recording was widely adopted. The clay tablet was thus being used by scribes to record events happening during their time. Tools that these scribes used were styluses with sharp triangular tips, making it easy to leave markings on the clay; [5] the clay tablets themselves came in a variety of colors such as bone white, chocolate, and charcoal.

Sumerians used what is known as pictograms. Early writing also began in Ancient Egypt using hieroglyphs. Early hieroglyphs and some of the modern Chinese characters are other examples of pictographs.

History of Ceramics

The Sumerians later shifted their writing to Cuneiform, defined as "Wedge writing" in Latin, which added phonetic symbols, syllabograms. Text on clay tablets took the forms of myths, fables, essays, hymns, proverbs, epic poetry, laws, plants, and animals. An example of these great stories was The Story of Gilgamesh. This story would tell of the great flood that destroyed Sumer. Remedies and recipes that would have been unknown were then possible because of the clay tablet.

Some of the recipes were stew, which was made with goat, garlic, onions and sour milk. By the end of the 3rd Millennium BC, BC , even the " short story " was first attempted, as independent scribes entered into the philosophical arena, with stories like: Communication grew faster as now there was a way to get messages across just like mail.

Important and private clay tablets were coated with an extra layer of clay, that no one else would read it. This means of communicating was used for over [6] years in fifteen different languages.

Sumerians, Babylonians and Eblaites all had their own clay tablet libraries. Fragments of tablets containing the Epic of Gilgamesh dating to BC have been discovered. A full version has been found on tablets dated to the 1st millennium BC. Tablets on Babylonian astronomical records date back to around BC. Tablets discussing astronomical records continue through around 75AD.

Papyrus was replaced in Europe by the cheaper, locally produced products parchment and vellum , of significantly higher durability in moist climates, though Henri Pirenne 's connection of its disappearance with the Muslim conquest of Egypt is contested. Oral and Textual Authority Biblical evidence clearly points toward early Israel as a society that looked to oral tradition as its locus of authority. Secondary or sedimentary clay is formed of lighter sediment that is carried farther in water and deposited. At times the differences create contradictions in the mind of the modern reader.
