MOULD PRESSING

by Rosa Barovier Mentasti
As far back as the 2nd millennium BC, pressed glass objects were produced in Mesopotamia and Ancient Egypt. Over the course of centuries, the technique was never abandoned.
Mould pressing is a quick and economical method for producing solid or concave glass objects.
A suitable amount of glass is poured from a crucible onto a surface and a refractory clay or metal mould is pressed onto the top part of it.
Then the semi-worked object can be placed on a convex mould to obtain a concave shape.
Pressing can also be carried out with a double mould, a bottom one and a top one, so as to give the glass object a whole solid or concave form.
Mould pressing nowadays is also carried out with automatic tools.
