Quality—from the literal meaning of the characters, "quality" (*zhi*) refers to the material nature, and "quantity" (*liang*) refers to the amount. In common parlance, it simply means whether something is good or bad. Quality encompasses two aspects: one is external appearance, the other is internal substance. The problem currently existing in our factory is that we focus only on external appearance and neglect internal quality. External quality is nothing more than surface scraping, smoothing, and polishing, whereas internal quality is what truly matters. Several aspects where products are prone to defects: 1. False bottom too thick or too thin; 2. Lid floating on top, not adhered tightly; 3. Carelessness when attaching the spout and handle; 4. Spout not hollowed out properly, middle section blocked; 5. Spout base and spout hole misaligned, blocking the spout hole; 6. Height of spout does not meet requirements (generally a teapot's spout should be level with the rim; those with knobs can be slightly lower); 7. Rim not uniform, one side wide and one side narrow, clay accumulated inside, inner rim cut too slanted, making the wall appear thin; 8. Clay strips used when forming the body too thick or too thin. Several operational methods to ensure internal product quality: 1. Good foundation; 2. Correct operational techniques and procedures; 3. Appropriate tools.
