The invention relates to a totally closed zero-air-outlet double-layer Jun porcelain heat preserving cup and a production method thereof. The heat preserving cup is prepared from the following raw materials in parts by weight: blanks: 15 parts of kaolin, 20 parts of sodium silicate, 20 parts of yellow gangue, 20 parts of gravel, 6 parts of quartz, 9 parts of knar clay, and 0.4 part of sodium carbonate; glazes: 57 parts of potassium feldspar, 10 parts of quartz, 14 parts of calcite, 4 parts of copper ore, 2 parts of talc, 3 parts of zinc oxide and 0.8 part of copper oxide; 8 parts of Benyao (a clay material special for Jun ware). The totally closed zero-air-outlet double-layer Jun porcelain heat preserving cup is strong in practicability, combines Jun porcelain and the household cup, has a high-end artistic effect, is meanwhile non-toxic and harmless, is obvious in heat insulation effect, can be used as the household porcelain after being fired, has no glaze in the internal structure, does not influence overall use, has the beauty of the Jun porcelain on the outside, well combines the Jun porcelain and the cup together, and meanwhile has no air outlets; according to the firing method, cracking can be avoided, and the defects that the conventional porcelain is fired into the cup with air outlets is overcome overall.
