Does anyone have access to Chapter #16 of the SGAA Reference & Technical Manual? It contains information on Hyrdofluoric Acid Etching, Processes, Methods and Safety. Or any other resources I could gain this knowledge from? I am having no luck finding specifics such as the concentration of acid used or what kind of resist to use with the stencils. Some articles say to use the fumes whereas others use the actual acid. Any help would be greatly appreciated.
This talk will be givin at The American Glass Guild conference in Philia.

Acid Etching: Tips on Setting Up a Safe and Effective Etching Station
This discussion will focus entirely on the subject of creating a safe, effective, and efficient environment for acid-etching on flashed glass.
Etched glass can add an entirely new dimension to stained glass; variations of etching and engraving have been used for centuries to add intricate detailing and texture to both representational and graphic elements in stained glass. This presentation will attempt to give the artist some tips on the safe handling and use of hydrofluoric acid when etching.
Among the topics to be covered will be:
Where to buy the materials needed to start. This will include chemicals for etching and neutralizing, etching trays, spill mats, rinse trays, ventilation systems, and the materials needed to build a self-contained ventilation station for the actual etching.
The safety equipment needed for working with acid.
The dos and don?ts of working with HFL, including the frequently asked concerns about wearing rubber gloves, and other safe handling procedures.
Tips on creating an etching station (similar in ways to a sandblasting box) that will expose the user and his/her studio to the least possible exposure to fumes emitted from the acid.
How to continually reuse and re-fortify the etching solution (much diluted from its original strength), and how to best store the acid solutions when not in use.
The presentation will include photos of a working etching station, and if time permits, photos of a new one under assembly. A complete list of all suppliers, with phone numbers and websites will be given to all participants. When feasible, samples of some of the materials (such as matting and safety equipment) will be on hand for viewing.
Finally, a large proportion of the discussion period will be left open to questions and answers; in fact, pertinent questions may be asked at any point in the discussion.
