The results indicate that the bodies of all samples were made from local raw material – porcelain stone, with the proto-porcelain samples being made from clay of higher quality. Wood ashes, high in lime and low in potash, were intentionally applied to the proto-porcelain samples, resulting in the formation of lime-rich glazes whose composition were determined by a temperature-controlled mechanism. In contrast, kiln fragments and furniture show a potash-rich fuel vapour glaze, which formed unintentionally during use of the kiln. The firing temperature for most of the proto-porcelain glazes is around the maturing temperature for typical more recent lime glazes, showing that the potters were already at such an early time able to attain sufficiently high temperature in their kilns. Keywords proto-porcelain, Shang and Zhou periods, Zhejiang, China, porcelain stone, glazing technique, firing temperature 1.

ASH GLAZES, LOCAL SLIP GLAZES and ONCE FIRE PROCESS BY Howard Skinner Technology- B.F.A. Rochester Institute of June, 1976 Preface My reasons for writing this thesis is to present my findings which have resulted from my explorations into the development of ash glazes, local slip glazes, once fire techniques and the production of an oriented ash glaze surface which will be consistent enough to be used on a steady line of functional dinnerware and accessories. Investigation into these areas was stismlated by a striving to join myself with the closeness of ash and natural clay glazes to the relation of the clay-forming process itself. Also the investigation has led toward the development of the once fire method which has resulted in great savings economically, time-wise, and ecologically. This once fire process joins the raw clay and slip clay ash glaze without taking away the fresh raw quality of the clay by being fired from raw clay to finished product in a one step process.

    Early 19th to Mid 20th Century Ceramics in Texas Becky Shelton, TASN Training Fort Worth, July 18th 2015 Adapted from: Sandra and Johnney Pollan and John Clark Texas Archeological Stewardship Network 2006 Workshop Presentations Ceramics generally fall into two categories: High temperatures Low temperatures Vitreous Nonvitreous 1. Stoneware Earthenware 2. Porcelain 1. Creamware 2. Pearlware 3. Whiteware 4. Red earthenware OET Porcelain Compact and grainy in cross-section with glassy edges. Used all decorating techniques to make decorative as well as useful wares. England developed two kinds of porcelain – hard-paste and soft-paste. Soft-paste porcelain is fritted with crushed glass. Bone China, or bone ash porcelain (fritted with glass and animal bone ash), became the standard English porcelain body throughout the 19th Century. It is more translucent than hard-paste porcelain. Its broken edges will discolor, and the overglaze decoration often wears away with use. Soft-paste porcelain: very Bone China: ivory, white, vitreous vitreous Earthenware • Fired at low temperatures • Coarse, porous clay bodies • Non-vitreous; require interior surface coating to prevent leakage • Opaque body; transmits no light • Includes “red wares, yellow wares, and white wares” Earthenware-Red • Coarse, porous body that is fragile and must be glazed to prevent leakage. • Pinkish buff to red to brown body • Wheel-thrown and drape-molded most common • Pre-1830: bulbous, ovoid shapes • Post-1830: Straight-sided cylindrical vessels • Decor: Slip-trailing, Manganese glaze, and simple Lead glaze Earthenware-Red, cont.
