This book is enormous, far longer and more complete than I had imagined. As others have said, it is not exactly a step-by-step "how to" for baking break or for building an oven, but it comes close. I like the word "treatise"If you are have been thinking about building your own masonry oven, this book has enough information to make that possible. Don't believe a word of what the whiner from Japan with absolutely no literacy or mechanical skills has said: this book does indeed contain outlines, guidelines, drawings, and more that will go a long way towards making a DIY masonry oven possible. however, if you have to be led by the hand the entire way, and given exact specifications for every board and every brick, then I guess this book isn't good enough for you...UPDATE (1/7/2012) --> I have now built a masonry oven following the plans laid out in this book. The oven takes between 3-4 hours to heat to 1000F and holds enough thermal energy to bake 100+ pizzas over a 2-1/2 hour period (we had a couple of huge pizza parties involving dozens of people). It vents perfectly, heats evenly, and produces crust TO DIE for!
