Armour"s 32 page Glass Etching book was created to fill the need for a more comprehensive instructional course of glass etching. Included is a brief history lesson, plus a section on the difference between chemical etching, sandblasting, and engraving, and the different types of glass available. Safety tips, creating special effects, the pros and cons of using various types of stencils, pattern transfer and scaling, and trouble shooting are just a few of the subjects covered.
