ABSTRACT:
The process according to the invention reduces the effort required to shape a glass piece. In this process a liquid glass piece is provided on a structured supporting surface of an electrically conducting base. A voltage is applied across the liquid glass piece by connecting a voltage source between a contact position on the liquid glass piece and the electrically conducting base. The apparatus for performing the process has an electrically conducting base on which the liquid glass piece is supported and a device for applying a voltage between a contact position on the liquid glass piece and the electrically conducting base.
