Question

What is the use of pyrometric cones in the Kiln?

• A. Checking color
• B. Measuring temperature
• C. Checking the colour of ceramic body
• D. Checking the firing quality

Hint:

Pyrometric cones do not measure temperature directly like a thermometer. Instead, they measure 'heat-work,' which is a more accurate gauge of how a ceramic piece has matured during firing.

Answer 1

The Correct Option is B

Step 1: Understanding Pyrometric Cones. Pyrometric cones are small, pyramid-shaped objects made of ceramic materials. They are designed to soften and bend at specific temperatures and over a certain time inside a kiln.
Step 2: Identifying their primary function. The primary purpose of these cones is to provide a visual indication that the kiln has reached a desired temperature and that the ceramic wares have received the right amount of heat-work (a combination of time and temperature). Therefore, their main use is to measure the temperature and the progress of the firing process.
