Exploring Spodumene as a Key Ingredient to Extend the Usage Life of Shiwan Kiln Earthenware

บทคัดย่อ

          Although Shiwan Kiln pottery is China's intangible cultural heritage, it encounters problems such as seepage, short usage life, due to using quartz sand materials. For these reasons, it is impractical for daily use and has limited application, especially in modern society. The research objectives were to: 1)  Improve the anti-leakage properties of Shiwan Kiln pots and 2) make them more durable. This study employed an experimental approach by: 1) Creating nine Kiln pots using the traditional materials composed of quartz sand, mud at high sintering temperature and tested them; 2) Explored and analyzed the properties of bentonite, cordierite, spodumene, and alumina as alternative materials to quartz sand by making Total of 12 samples;3) Selected the most suitable material and created additional 18 samples to test the validity of the material 4) The impact of experimental firing methods on  pots.
          The results show that after authoritative testing, spodumene ceramics demonstrated low water absorption of 0.3%, excellent thermal shock resistance and environmental compliance; its ceramic strength, density and corrosion resistance increased by 30%, 20% and 20%, respectively. 15%. These results provide a critical scientific basis for the material selection and production process optimization of Shiwan kiln pottery pots, thereby significantly improving the leakage prevention and durability of the products. This research provides new possibilities and a practical basis for technological innovation of Shiwan kiln ceramic production.
