Question

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: A glaze is essentially a combination of ceramic materials designed to melt and adhere as a glassy coating to fixed ceramic object.
Reason R: Alumina is refractory and does not melt by itself until about $2040^{\circ}C$ For this reason not much alumina can be added to a glaze.
In the light of the above statements, choose the most appropriate answer from the options given below

• A. Both A and R are correct and R is the correct explanation of A.
• B. Both A and R are correct but R is NOT the correct explanation of A.
• C. A is correct but R is not correct.
• D. A is not correct but R is correct.

Hint:

Logic Tip: A glaze is melted glass (A). Alumina is hard to melt, so use it sparingly (R). Both are true, but R is a specific recipe rule, not the reason why glazes exist.

Answer 1

The Correct Option is B
