I have been looking for relatively easy information on glaze materials and recipe creation for some time and happened upon this book by chance. It's a great read for those who are really interested in getting to know the in's and out's of glaze creation. Detailed info on glaze material, what makes a glaze, and how to adapt to your own needs. As previous reviewer says more coloured pictures would be good, maybe in editions later than 1978 they have these? Not a book for anyone just wanting glaze recipes.
