Sintering process of tillite tea ware

Abstract

The invention discloses a tillite tea container. The tillite tea container is formed by firing a blank; the blank is prepared from the following raw materials in percentage by weight: 56 to 78 percent of tillite raw stone, 12 to 35 percent of copper functional old pottery clay and 5 to 16 percent of plant ash; according to the tillite tea container, the tillite raw stone, the copper functional old pottery clay and the plant ash are adopted as raw materials to manufacture the tea container, and the overall cost is much lower than that of tillite raw stone sculpture. The air permeability of the tea container is good, fragrance and essence of tea leaves can be fully released, and brewed tea soup is more fragrant, smoother, fresh, sweet and delicious. And meanwhile, the heat preservation function of the tillite tea container can continuously preserve heat, so that people can feel deep deposits of tea culture while enjoying tea. According to the firing process of the tillite tea ware, the tillite tea ware is fired through primary firing, intermediate firing and at least one re-firing, so that the fired product is finer and smoother, and the heat preservation effect is better.
