Conditioning
Gob temperature uniformity
The variance of gob temperature across consecutive gobs and across sections — the headline KPI of forehearth performance. ±5 °C is good; ±10 °C+ degrades pack rate materially.

Gob temperature
Temperature of the gob at delivery to the blank mould — typically 1080–1180 °C depending on glass colour and process. Variance ±5°C is acceptable; ±10°C+ degrades pack rate.
Forehearth
The conditioning channel between the working end and the IS machine that delivers thermally uniform glass at the gob delivery point. The most critical conditioning element.
