I was originally going to do a computer seminar for stained
glass artists at the 2014 AGG conference, but we toured the building
where the workshops are taking place and the facilities for a computer
course are limited. Plenty of empty classrooms. but no computer lab.
But what the Doering Center does have are excellent science labs,
which presents a rare opportunity to do an acid etching workshop.

The official description -
Taking advantage of the science lab facilities at the Doering
Center of Bryn Athyn College, Tom Krepcio will conduct a
workshop in the etching of flashed glass using hydrofluoric acid.
Topics covered will be the safe setup of an acid etching space,
the application and advantages of a variety of acid resists, and
what equipment is needed depending on what scale you are
working at. There will be a comparison of sandblasting,
engraving and acid etching, with samples showing where each
has advantages and disadvantages. The differences in the
etching qualities and times of different flashed glasses will also
be looked at. Most importantly, we will look at how, in all instances,
to work safely with hydrofluoric acid. This is a unique chance to
take a workshop in this fascinating process.

Due to safety issues, it will be a limited hands-on workshop,
depending on how many people sign up. There is only room for 4-6
open trays of acid going during the class (open inside a well ventilated
chemical hood of course). The emphasis will be on demonstrating a
wide variety of situations (different flashed glasses with different
acid strengths and different acid resists, etc.).
