Lithium-free high-thermal-shock-resistance Jianshui purple pottery heat-resistant pottery clay material

The invention relates to a lithium-free high-thermal-shock-resistance heat-resistant clay material for Jianshui purple pottery. The heat-resistant clay material is prepared from the following components in percentage by weight: 1t in particle size; 0.061 mm of Jianshui purple pottery clay or/and loess, and quartz sand with the particle size of 0.6 mm-0. 061 mm and the particle size of 1t; the mass part ratio of the Jianshui purple pottery waste ceramic powder to the Jianshui purple pottery white mud clinker powder to the Jianshui purple pottery red mud clinker powder is (70-90): (5-20): (5-20). The heat-resistant clay material for the Jianshui purple pottery is used for manufacturing a Jianshui purple pottery product, so that the thermal shock resistance of the product can be improved, meanwhile, the production cost is greatly reduced, and the market competitiveness of the product is improved. 一种不含锂的高抗热震性建水紫陶耐热陶泥料，所述建水紫陶耐热陶泥料由粒径
