Forehearth Selection Considerations

With a lifetime's involvement in the world of forehearths, John McMinn admits to a fascination with forehearths and how they operate. The company has conducted forehearth audits and troubleshooting on all mainstream, as well as some slightly more bizarre systems. These technical audits identify exactly how individual forehearth designs operate under production conditions, how they perform with different glass colours, how fast they react to temperature variations, which design provides greater gob temperature and tonnage ranges etc and crucially, what steps need to be taken to return the systems to optimal performance.
