The Correct Option is C
Solution and Explanation
Concept:
The Danner process is a glass forming process used mainly for producing glass tubes and rods continuously.
Step 1: In the Danner process, molten glass flows over a rotating mandrel.
Step 2: Air is blown through the center to form a hollow tube.
Step 3: The tube is drawn continuously and cooled.
Step 4: By controlling pulling speed, air pressure, and glass flow, rods or tubes of desired size are obtained. Therefore, the Danner process is: \[ \boxed{\text{Continuous process for drawing rods \& tubes}} \]
