Concept:
Ceramic sculpture preparation follows a systematic process from clay preparation to final firing.
•
Step 1:
Grog is mixed into clay to reduce shrinkage and improve structural strength.
•
Step 2:
The sculpture is then shaped and constructed.
•
Step 3:
The work is dried slowly and surface finishing is completed.
•
Step 4:
Glaze is applied after proper drying.
•
Step 5:
Finally, the sculpture is fired in the kiln.
