Query: Indispensable, but not infallible

This really is an indispensable book for anyone seriously interested in pottery as an art or profession. It contains lots of great information. It also contains some errors, most of which are little. Also, the rendition of the Chinese character for "raku" is ugly and missing a stroke. The title says this is a dictionary of materials and techniques - but it's more than that. It can serve as a jargon glossary, too. Also, some articles seem more concerned about meaning and interpretation and make practically no mention of materials or technique, and in the case of the "Teapots" entry, I thought it culturally-biased and incomplete. That said, get it anyway, this book is a must-have.
