The production of ceramic tableware is an art that combines traditional craftsmanship with modern technology. Below are the main steps in the manufacturing process:
Raw Material Preparation
The first step in making ceramic tableware is selecting the right raw materials, primarily kaolin, quartz, and feldspar. These materials are carefully screened and mixed to ensure a uniform texture.
Shaping
The mixed materials are shaped into the initial form of the tableware through molding or hand-throwing. Common shaping methods include slip casting, press molding, and wheel throwing.
Drying
The shaped ceramic bodies are dried naturally at room temperature or using drying equipment to remove excess moisture and prevent cracking.
Trimming and Carving
After drying, the bodies are trimmed to remove rough edges and uneven surfaces. If needed, carving or stamping can be added to enhance the artistic appeal.
Biscuit Firing
The trimmed bodies are fired in a kiln for the first time, known as biscuit firing. The temperature typically ranges between 800°C and 1000°C, hardening the bodies and giving them strength.
Glazing
After biscuit firing, the ceramic surfaces are glazed to add shine, water resistance, and durability. The glaze can be transparent or colored, depending on the design requirements.
Glaze Firing
The glazed ceramics are fired again at high temperatures, known as glaze firing. The temperature usually ranges between 1200°C and 1400°C, allowing the glaze to fully fuse with the body and create a smooth surface.
Quality Inspection and Packaging
The finished ceramic tableware undergoes strict quality checks to ensure there are no cracks or defects. Qualified products are then packaged and prepared for shipment.
The craftsmanship of ceramic tableware not only reflects the essence of traditional handiwork but also incorporates modern technology, ensuring that each piece is both beautiful and practical.
