Which description best explains how a glass-ceramic is produced?
- A
It begins as a crystalline ceramic and is melted until all crystals disappear.
- B

A kiln lining must endure high temperatures and exposure to chemically aggressive substances. Which material application is specifically suited to these conditions?
- A
A glass lens, because it is transparent
- B
A ceramic seal, because it resists wear
- C
A refractory lining, because it withstands high temperatures and chemical attack
- D
