The Art of Firing

Book excerpt: This book is a guide to the principles involved in firing kilns. In The Art of Firing, Nils Lou reflects on his lifetime passion for kilns, helping us to understand how kilns work, and giving us access to that chamber of mysteries. He also discusses the structure of various fuel-burning kilns and explains how kilns work. While he accepts that potters tend to fire kilns by 'the seat of their pants', he firmly believes that a sound knowledge of the science involved is necessary to underpin the intuitive approach. Looking into the spyhole of a kiln through a safety lens is a captivating experience. At temperature, molten glazes can reflect as mirrors do. For predictable and reliable results we need to know how pots react to atmospheric changes both inside and outside the kiln, how to diagnose problems so results can be improved and how to eliminate poor firings. Inconsistent reds and other fugitive glazes, stalling just before maturity, propane gas freeze-up, and inefficient fuel consumption are among the common problems, but all are solvable. In this book you will find the kind of working information you can use to make your kiln perform properly and efficiently. Nils Lou's unique curiosity about the behaviour of kilns makes this book a treasure trove for a newcomer to firing, as well as to an experienced potter with a yearning to push past old myths and blind spots about kiln firing.-- 9.
