Today window glass is produced non-stop. A modern float glass plant produces around 6000 kilometres of glass each year. This adds up to more than 50 million tons of glass a year spread across the approx. 500 plants worldwide. It certainly has not always been this easy. Although it was possible to make glass beads and blow bottles out of glass many thousands of years ago, the road to making flat glass sheets has been long and winding.
Displayed in the museum are descriptions of the historical techniques that were used to produce plate glass for windows: Roman cast glass, Cylinder glass, Crown glass, Cast mirror glass, Rolled plate glass, Drawn sheet glass and Float glass. The seven techniques are unfolded and described through physical glass works, speak, photos and film.
