 **INTRO |** WHAT IS THIS GLASS SECTION ABOUT ? *As I am working for a short mission at the Cerfav (European Center for Research and Formation in glass Handicrafts in France) I am discovering a lot of references that echo the previous Fabricademy assignements. I need somewhere to document them and this documentation website seems a good place to start ! For the moment I have decided to separate them from the textile assignements. We'll see how it goes !*

 **02 |** GLASS & DIGITALITY *How does glass work is happening in our digital context ?*
 Going digital for glass seems pretty far away from the reality of this material. However, there is something in the transparency of glass that somehow connects with digital. The sensation that it always escapes through light and surprising effects into a non tangible world, a bit like a digital feeling.
