Does anybody know or give me a reference where to find the volume change of glass from cast to hardened material.

You need to define what you mean. Do you mean the change from the immediately formed hot object to the cooled and annealed object? Or do you mean the internal volume change of a container, from the freshly formed hot condition to the cooled and annealed state?
Or do you mean something else?
