Question

How the pyrometric cones help in the process of pot making?

• A. To dry the clay
• B. To make the clay
• C. To know the temperature
• D. For casting

Hint:

Pyrometric cones are essential tools for monitoring kiln temperatures, ensuring that firing is done correctly.

Answer 1

The Correct Option is C

Step 1: Understanding Pyrometric Cones.
Pyrometric cones are used to measure the temperature inside a kiln during the firing process. They are specifically designed to bend at certain temperatures, providing an accurate reading of the heat within the kiln.
Step 2: Analysis of options.
- (1) To dry the clay: Incorrect, pyrometric cones are not used for drying clay.
- (2) To make the clay: Incorrect, cones are not used to make clay.
- (3) To know the temperature: Correct, pyrometric cones help determine the temperature inside the kiln.
- (4) For casting: Incorrect, casting involves pouring clay into molds, which is not the function of pyrometric cones.
Step 3: Conclusion.
Thus, the correct answer is (3) To know the temperature.
