Question

Using cullet in glass making increases the energy requirement.

(a) True

(b) False

This question was addressed to me during an interview.

This interesting question is from Manufacture of Glass in portion Glass Packaging Materials of Food Packaging Technology

Answer 1

Correct answer is (b) False

To explain I would say: The given statement is false. Cullet also reduces the amount of dust and other particulate matter that often accompanies a batch made exclusively from new raw materials.  The use of cullet is economically desirable since less energy is required to melt cullet than new raw materials.
