From Mud to Masterpiece
Pottery, an ancient and rich art, involves crafting diverse objects with ceramic materials like clay.
Items range from daily necessities to artworks and sculptures.
Main Steps of Pottery:
Preparing Materials: Pottery begins with selecting and preparing clay, a highly plastic soil shaped by hand-kneading.
Modeling: Artists use hand techniques to create desired shapes, allowing for creative expression through various ideas.
Drying: After modeling, pieces naturally dry at room temperature to prevent cracking during firing.
Decoration: Before complete drying, artists may decorate surfaces with scoring, painting, or glazes.
Firing: Pottery undergoes firing in a kiln, where clay hardens, and decorations and glazes meld at high temperatures.
Glazing: Some ceramics receive glaze coatings pre-firing for specific textures and colors, with glaze treatment crucial for the final look.
10 Whys in Pottery:
1. Why Cracking After Firing?
Uneven control of clay dryness and humidity during creation.
Thin thickness.
Internal injuries pre-firing.
Rescue Method: Maintain optimal moisture; smooth cracks with water; fill and smooth with thicker mud if cracked.
2. Why Clay Tablets Shrink After Drying?
Clay tablets naturally shrink after drying and firing.
Rescue Method: Use a water-absorbing wooden board for cooling; to prevent warping and deformation during drying.
3. Why Does Blank Turn Yellow Over Time?
Yellowing due to oxidation with air (moisture, dust) during long-term storage.
No impact on the final firing; can be glazed and fired after replenishing water.
4. Why Does Newly Purchased Mud Dry Quickly?
Mud is composed of water and soil, leading to normal water evaporation.
Rescue Method: Add water to bulk mud; store in a cool place; refine and recycle waste mud.
5. Why Isn't the Purchased Mud Material White?
Whiteness varies based on clay-producing areas.
Quality judgment after firing; better quality porcelain clay yields whiter results.
6. Why Aren't Burned Works White Enough?
Different types of porcelain clay are based on processing and iron removal.
Varying standards among manufacturers; firing temperature influences whiteness.
7. Why Do Mud Colors Differ Inside and Outside?
Mud's water content results in color differences due to varying dryness and humidity.
No impact on use; knead thoroughly before making.
8. Why Were Works Burned?
Excessive temperature exceeding the clay material's maximum resistance results in carbonization or melting.
Rescue Method: Set kiln temperature according to mud material characteristics; avoid excessive heat.
9. Why Does Carcass Burst After Burning?
Neat fractures due to fast cooling, unsatisfactory base-glaze bonding, and internal base damage pre-firing.
Solution: Slow down the cooling rate.
10. What Causes Glaze to Flow and Clump After Firing?
Glaze flows to the bottom due to high kiln temperature and insufficient scraping.
Rescue Method: Adjust kiln temperature; ensure proper glaze application and scraping.
Ceramics, an ancient art form, serves both practical and artistic purposes, reflecting creativity and aesthetics while preserving cultural heritage across regions and periods.
