Step 1: Understanding Ceramic Extrusion.
Ceramic extrusion is a process that is used to create continuous shapes, usually cylindrical or tubular forms. The clay is forced through a die to form the desired shape.
Step 2: Analysis of options.
- (1) Irregular, asymmetrical forms: Incorrect, these are difficult to produce with extrusion because extrusion produces uniform shapes.
- (2) Flat tiles: Incorrect, flat tiles require rolling or pressing, not extrusion.
- (3) Cylindrical or tubular forms: Correct, these are the easiest shapes to produce using ceramic extrusion.
- (4) Hand-carved figurines: Incorrect, hand-carved figurines require sculpting, not extrusion.
Step 3: Conclusion.
Thus, the correct answer is (3) Cylindrical or tubular forms.
