Step 1: Understanding the Final Firing Stage.
The final firing stage in ceramics is called glaze firing. During this stage, the glaze matures, and it adheres to the surface of the ceramic, creating the desired finish.
Step 2: Analysis of options.
- (1) Greenware firing: Incorrect, greenware refers to unfired clay that is still in the soft, malleable state.
- (2) Bisque firing: Incorrect, bisque firing is the initial firing stage to harden the clay before glazing.
- (3) Glaze firing: Correct, this is the final firing process that fixes the glaze onto the ceramic.
- (4) Raku firing: Incorrect, raku firing is a low-temperature firing technique used for a unique surface finish.
Step 3: Conclusion.
Thus, the correct answer is (3) Glaze firing.
