Question

Match the LIST-I with LIST-II

• A. A-IV, B-III, C-II, D-I
• B. A-III, B-II, C-I, D-IV
• C. A-III, B-IV, C-I, D-II
• D. A-II, B-III, C-I, D-IV

Hint:

Logic Tip: Crawling always means "bare spots." Shivering is dangerous (serious flaw) because glass splinters off.

Answer 1

The Correct Option is C

Concept:
Identifying standard ceramic glaze defects and their specific characteristics or causes. *(Note: The source text contains typographical errors, using "flow" instead of "flaw").*

Step 1:
Crazing is a network of fine cracks in the glaze caused by the glaze shrinking more than the clay body. It is the most universally common glaze flaw encountered by potters. (A-III)

Step 2:
Crawling occurs when the glaze pulls away from the surface of the clay during the firing melt, bunching up and leaving bare spots of clay exposed. (B-IV)

Step 3:
If a traditional lead glaze is exposed to a carbon-heavy reducing atmosphere, the lead compound reduces to metallic lead, bubbling and violently boiling to cause severe blistering on the surface. (C-I)

Step 4:
Shivering is the opposite of crazing; the clay shrinks more than the glaze, causing the glaze to literally buckle and flake off like razor blades. Because shards of glass pop off into food or hands, it is considered a certainly serious flaw (safety hazard). (D-II)

Step 5:
Matching these gives A-III, B-IV, C-I, D-II, which corresponds to Option 3. \[ \boxed{\text{(3) A-III, B-IV, C-I, D-II}} \]
