Just as everyone else says: It is a really great reference book - everything from safety, setting up studio, selecting equipment (pros and cons), and even how to make some tools. Plus lots of information on Effetre glass and boro - recipes, problem solving, etc.
If you have a question about something glass related, the answer just might be in the book. There is so much information in the book!
The instructions for the marbles can readily be adapted to beads.
