Question

Which of the following materials is commonly used as insulation in kiln construction?

• A. Aluminum
• B. Concrete
• C. Fiberglass
• D. Copper

Hint:

Fiberglass acts like a thermal blanket, keeping heat inside the kiln. Other materials cannot insulate as effectively.

Answer 1

The Correct Option is C

Fiberglass is widely used as kiln insulation due to its low thermal conductivity and excellent heat retention. Materials like aluminum, concrete, and copper lack the necessary insulation properties.
