Bubbles for Puntied Mould Blowing
- thick & wider neck
- thin bottom
Bubbles for mould blown glass items that require a punty have some of the attribute of the mould blown bubbles but there is no cut in mark and the glass that surrounds the iron is much thicker. This allows for much longer lengths when dropping while still keeping the neck thick enough. Trying to blow a 30cm decanter in a mould using a bubble that was made for a free hand decanter will end up on the floor because the thickness polarity has to be revered when blowing glass items in a mould.
