Dalle-Glasses are individually created by means of a hand casting procedure. Their surface is smooth with occasional open bubbles or streaks. The slabs have a standard size of 20x30 cm. and are approx. 24 mm thick. Due to the casting by hand thethickness can vary somewhat. Larger sizes are available by special order.
The moment the molten glass has been taken from the oven, it is cast into iron molds resting on top of thick slabs of graphite. After a short period of cooling the pieces are taken to an annealing oven where they slowly lose their tension.
Dalle-Glasses are incorporated into fabricated concrete units, steel and wooden frames.
