I got this question during an interview for a job.

This intriguing question comes from Manufacture of Glass topic in portion Glass Packaging Materials of Food Packaging Technology

Answer 1

Correct option is (a) True

To explain I would say: The given statement is true. The glass is carried from the working end of the furnace to the forming machine in a channel-like structure called a forehearth, which is fired by a number of small burners, the aim being to ensure uniform temperature distribution throughout the depth of the glass. The glass then passes through a gob-forming mechanism which consists of a rotating sleeve and vertical plunger.
