This book is intended to show the professional stained glass painter the simplest method of acid etching flashed glass. While in my experience, the simplest method is generally the safest, you should read this entire book before actually proceeding on to your small etching project. I feel that acid etching, more appropriately called aciding in the stained glass trade, is as much a process of stained glass painting as any other, and therefore, necessary for the stained glass painter to learn. Now it's true, no book can communicate this technique as well as a good teacher. If you are on your own, however, as so many people are, this book will be useful. I hope you find this book valuable in your exploration of this beautiful process of stained glass and helpful in your endeavor to learn these simple aciding techniques based on my own practical experience.
