Query: this book is horrible

Around my studio we had a copy of this book that no one would take and everyone laughed at. The work shown in the book is terrible- i mean really really bad art- dated and just ugly. The glazes are dated too- some even using lead (a poison that should only be used if you really know what you are doing). The only plus i can say for this book is that it has luster recipes -something i've never seen anywhere else(it's made of frit and bismouth subnitrate or something) all in all BUY A DIFFERENT BOOK! there are much better ones out there or start getting magazines (ceramics monthly and claytimes) that always have lots of glaze recipes and articles.
