paste mold
glassmaking
Quick Summary
A paste mold is an iron mold lined with a wetted material, such as cork or pasted sawdust. This lining creates a steam cushion when hot glass is blown into it, resulting in a smooth finish on the glass object, typically tableware like tumblers. The glass is rotated within the mold during blowing. After forming, the glass is detached from the blowing pipe, and the rim is finished with a flame. This technique is a method of glass forming where viscosity is a key property, allowing the glass to be shaped before solidifying.12
