I learned to fuse with Kaiser's first book, Introduction to Glass Fusing, and when I saw she had a second book; I couldn't wait to read it! It is written in a similar style -- a lesson is given to complete a specific project and teach specific technical techniques. This "learn-by-doing" appeals to me more than a book that is full of technical information with some projects at the end.
What I love about the new book:
1) I like the fusing schedules gathered together on one page at the front of the book.
2) I like the discussion of each stage of the fusing process.
3) However, for me, Lesson 1 & 2 are more than worth the cost of the book! Lesson 1 is jewelry techniques using fine silver and embedding CZ's. Lesson 2 is about making jewelery displays. I immediately ordered some fine silver to try out the jewelry ideas!
Should you get book 1 or 2? Well, I think they are affordable enough and the projects lovely enough to own both. But here are some factors to consider.
Book 1 seems to have a few more projects to do in a small kiln (less than 8"x8"). It has a section that walks you through a fusing session. My first fusing session, I had the book in hand watching carefully and a fire extinguisher near by. Now I laugh at my early concerns. But I felt like I had someone holding my hand. There are detailed discussion about everything a newbie should know -- for instance whether to use thinfire or kiln wash.
Book 2 -- most of the projects are for a medium kiln. However, there is enough information that a newbie could use this book as a starting point. There is lots of information on molds and some information on pattern bars and combing which are not in the first book. And, the jewelry section that I mentioned above.
If you're looking for a book to start you in glass fusing, then either or both of Kaiser's book are worthwhile investments.
