Logic Tip: Luster is metallic, so it must go "over" a finished glaze (A-II). Ash glazing uses wood ash (D-III). Matching these two provides the answer immediately.
Concept:
Different ceramic glazing techniques have highly specific application methods and material requirements.
•
Step 1:
Luster is a thin metallic coating. Because the metals would burn off at high temperatures, luster must be applied as an over glaze decoration on an already fired and glazed pot, then fired again at a very low temperature. (A-II)
•
Step 2:
Salt glazing is an atmospheric firing technique. You do not paint the glaze on. Instead, the ware is put in the kiln raw, and salt is thrown into the firebox at peak temperature, vaporizing to create a glass coating on the pots. (B-IV)
•
Step 3:
A slip glaze is essentially a liquid clay mixture. Because it shrinks similarly to the pot itself, it is traditionally applied over raw ware (greenware) before it is bisque fired. (C-I)
•
Step 4:
As the name implies, ash glazing utilizes the natural fluxes found in wood and vegetable ashes to create beautiful, earthy glazes at high temperatures. (D-III)
•
Step 5:
Combining these matches results in the sequence A-II, B-IV, C-I, D-III.
\[
\boxed{\text{(2) A-II, B-IV, C-I, D-III}}
\]
