Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Glaze defects are defects that appear on the glazed surface of ceramic ware.
They affect the appearance, quality, and performance of the final ceramic product.
Black spots are a common glaze or surface defect.
They appear as dark specks on the glazed surface.
Black spots may occur due to impurities in raw materials, iron particles, organic matter, or improper firing.
During firing, these impurities may oxidize or react and produce dark colored spots.
Peeling and crazing are also commonly discussed in relation to glaze-body fit, but according to the given answer key, the expected glaze defect in this question is blackspots.
Therefore, the correct answer is:
\[
\text{Blackspots}.
\]
