"Ceramic Science for the Potter" is an absolutely GREAT book.... but not a "starter" book. Too much information in the wrong format. It assumes some decent knowledge. As I remember ,... it is also expensive on the used market (not sure).
The best 'starter stuff' is getting Insight Level II and the nice little "Magic of Fire" book that comes with it and the access to the secure info on Digitalfire.com. Then work thru the tutorials in order... and follow the other stuff in Magic of Fire. I now use that as the "text" for my Ceramic Materials I course at the college...and have for a few years.
"Clay and Glazes for the Potter" (Robin Hoppoer revised edition is best now) is a good first book .... but the price is crazy now.
