This book has a little of everything. If you are just starting out in tile-making it would be an excellent choice. There are a LOT of different decorating techniques, and a very wide range of applications. The book is laid out well, with plenty of photos, so you can see finished examples of the techniques being described in the text below on the page. It would be an excellent beginner-to-novice book.
Personally, I prefer Frank Giorgini's "Handmade Tiles", because it has more technical information, glaze recipes, firing information, etc., but if I were starting out to make tiles on my own and taking them elsewhere for firing, I think Pozo's book would be a better choice.
