Taiwan Liangshi Meiware [Celadon] Covered Bowl

Title of work: Celadon covered bowl Author: Liangshi Meiqi Dimensions: cup diameter including lid 9mm x height 100mm base chassis diameter 120mm x height 25mm Capacity: 180cc Year of creation: 2024 Construction method sharing analysis: A series of processes and technologies in the process of making celadon, including raw material selection, shaping, glazing, firing and other aspects. The construction method of celadon pursues the delicate glaze color, the smoothness of the glaze surface and the artistic effect of the overall object. The following are the main process steps and techniques for making celadon: 1. Raw material selection Clay: Celadon usually uses kaolin (the main component is kaolin and some Stone), which is pure white and has a fine texture after firing. Glaze: The main ingredients are feldspar, quartz, sodium, chromium, iron, etc. Different raw material ratios and ingredients will affect the glaze color and texture of celadon. 2. Molding process Hand shaping: Using techniques such as hand kneading and drawing to make celadon objects. This requires craftsmen to have high skills to ensure the precise shape of the utensils. Mold forming: Mass production through molds to ensure consistency and accuracy of shapes. Wheel shaping: Use rotating wheels for shaping to make the objects more uniform and symmetrical. 3. Dry Natural drying: After celadon is formed, it needs to be naturally dried in a well-ventilated environment to avoid cracks caused by uneven water evaporation. 4. First firing (plain firing) Temperature control: The initial firing temperature is usually between 900°C and 1000°C. The purpose of this process is to remove moisture and organic matter from the clay and to initially fix the shape of the clay. Firing equipment: Commonly used ones include electric kilns, wood-fired kilns, etc. 5. Apply glaze Glaze preparation: Glaze needs to be prepared according to the formula, usually composed of minerals such as feldspar and quartz, with a certain proportion of iron, cobalt, chromium and other pigments added. Glazing method: Commonly used methods include brushing glaze, dipping glaze, spraying glaze, etc. Each method affects the thickness and uniformity of the glaze layer. Drying: After glazing, the object needs to be thoroughly dry to prevent the glaze from flowing during firing. 6. High-temperature firing (glaze firing) Firing temperature: The glaze firing temperature for celadon is usually between 1150°C and 1300°C. The exact temperature depends on the glaze recipe and desired effect. Atmosphere Control: Depending on the firing atmosphere (oxidizing or reducing), the color of celadon will vary. Reducing atmospheres are often used to obtain deep cyan colors, while oxidizing atmospheres may cause celadon to appear brighter. Firing equipment: Commonly used kilns include electric kilns, wood-fired kilns, etc. Different types of kilns can affect the texture and color of the glaze. 7. Cooling and inspection Cooling: After firing, celadon needs to be cooled slowly to prevent cracks or glaze problems caused by rapid temperature changes. Inspection: After cooling, the celadon is inspected to confirm that the glaze is even and free of blemishes or defects. 8. Post-processing Trimming: If necessary, post-trimming or polishing can be done to improve the appearance and texture of the celadon. 9. Decorative craftsmanship Carving: Carving on the surface of celadon objects to increase decoration. Common carving techniques include engraving, printing, etc. Decals: Decorate with a variety of paints or metals to add an artistic effect. The craft of celadon involves a wealth of technical and artistic means. Each step requires the exquisite skills and experience of craftsmen to produce celadon objects with beautiful colors and unique textures.
