Gather Weight & Piece SizeFurnace Guild
Convert glass gather weight to finished dry piece volume and dimension projections (hollow spheres, cylinders, bowls) based on thickness.
Thickness of hollow blown walls. Thick glass takes longer to anneal.
Important Size Note:
These dimensions are calculated based on constant wall thickness of 5 mm and uniform geometry. In real glassblowing, wall thickness varies slightly at the neck and base.
