Learn the science and artistry behind the materials that shape your ceramic practice, from geological origins to finished glazes. Understanding how and why clay and glazes work (or don''t) is a fundamental skill needed by all potters and ceramicists. Material Matters reveals the science and technology involved in making and firing ceramics, explaining the property and behaviour of various raw materials based on their underlying chemistry. Suitable for both amateur and experienced potters, the topics explored include raw materials, clay types, slips, glaze development, colourants and firing techniques - as well as the safety and sustainability tips you''ll need along the way. Supported by full colour illustrations, photographs, charts and graphs, and written by ceramic arts professor Linda Swanson and glaze expert Linda Bloomfield , Material Matters is the essential guide to working confidently with ceramics.

Autorentext
Linda Swanson is an artist whose interests are grounded in the metamorphic nature of ceramic materials and processes. Her works have been exhibited around the United States, Canada and Europe with recent exhibitions at the Musée National de Sèvres in Paris, Galateea Contemporary Art in Bucharest, Art Paris with Galerie Maria Lund, the DePaul Museum in Chicago and the Milwaukee Art Museum. Linda Bloomfield trained as a materials scientist before fulfilling her dream of becoming a potter. She has made thrown porcelain tableware in her West London studio since 2003 and sold her various ranges in Liberty and Harrods.
