Technique which allows to shape a sheet of glass on a mold previously created on purpose. Hollow, convex, tortuous shapes, bas-reliefs and special textures can thus be created…
It is also possible to use a simple glass sheet or a pane obtained from a previous fusion.
The sheet is placed on the cast and then heated to reach a temperature of about 700/750°C, the point in which glass starts to soften, taking the shape of the mold .
The molds can be made in plaster or fireclay, fiberceramic or steel.
The glass pane heating and cooling processes have to be extremely slow, calculated on the size and thickness of the piece, to avoid tensions and breaking .
