GLASS_QUIZIZZ_WEEK8

Mixture of sand, silica, soda ash, lime is also known as..

• Frit

• Cullet

20% of waste glass is also known as..

• Frit

• Cullet

Name the 4 stages of glass manufacturing.

What is the temperature inside the regenerative furnace when the frit and cullet are heated? (in degree celsius)

• 2000

• 1050

• 1500

• 1000

What happens during melting process?

• Waste broken glass (cullet) along with frit, usually in the proportions of 80% frit and 20% cullet are heated in a regenerative furnace tank at 1500 degree celsius.

• Molten glass will go through rolled process or float process at a temperature of between 650 - 1050 degree celsius.

• Glass ribbon will pass on a slow moving conveyor belt through the annealing lehr.

• Cutting, grinding, polishing, treatment, packaging, stacking.

Which one of these occurs during forming process?
