MINTS DESCRIPTION OF THE CELADON PROCESS
Celadon porcelain is a type of ceramic that is known for its distinctive pale green glaze. The process of making celadon porcelain typically involves several steps, including:
1. Clay Preparation: High-quality clay is selected and prepared, often by mixing different types to achieve the desired characteristics.
2. Shaping: The clay is shaped into the desired form, whether it be a bowl, vase, plate, or another item.
3. Drying: The shaped clay is left to dry thoroughly. This can be done naturally, but in modern production, controlled drying processes may be used.
4. Bisque Firing: The dried clay is fired in a kiln at a relatively low temperature. This process is known as bisque firing, and it hardens the clay, making it more stable for glazing.
5. Glazing: Celadon porcelain is known for its characteristic pale green glaze. The glaze is applied to the bisque-fired item. It is made from a mixture of specific minerals and has a unique composition that produces the desired colour when fired.
6. Glaze Firing: The item is fired again, this time at a higher temperature, to melt the glaze and create a smooth, glass-like surface. The specific firing temperature is crucial in achieving the celadon’s signature colour.
7. Cooling and Inspection: After the glaze firing, the item is allowed to cool. It is then inspected for any imperfections or flaws.
8. Final Touches: Depending on the design, additional details or decorations may be added at this stage.
9. Final Firing (Optional): In some cases, a final firing may be done to set any additional details or decorations.
The term “casting” is not commonly associated with celadon porcelain. Instead, it is more often used in processes like slip casting, where liquid clay (slip) is poured into a mold to create the shape. Keep in mind that specific techniques and variations can exist within the celadon-making process, and different artists or workshops may have their own unique methods. This is why XiaoXianTan is recognised at a national level in China, due to the special technique enabling this colour
