Carole Murphy, President of Pacific Northwest Sculptors, will be giving a workshop on Sculpting Autoclaved Aerated Cement at the Silver Falls Symposium Aug 27-Sept 1, 2011.
Carole was more than generous with her time on the phone telling me a little more about the medium and its potential.
Here are some of the things I learned:
Having come from a background of working with various media, including bronze, glass and poured cement, Carole was looking for a lighter medium and spent several months researching different products. She came upon Autoclaved Aerated Cement and liked it for its green qualities (it weighs about 1/5th as much as cement cutting down on transportation costs) as well as its ease of carving. 
To learn more about how to work with this interesting material and have hands-on time with it, be sure to look in on Carole's workshop at Silver Falls in September. Carole will be showing slides of her work along with some of her students' works in a presentation in the first part of the symposium.
