Method for manufacturing dark-red enameled pottery by double-layer grouting method

The invention discloses a method for manufacturing a dark-red enameled pottery through a double-layer grouting method. The method comprises the following steps that: grouting and demolding are carriedout, grouting is divided into two times of grouting, the two times of grouting comprise the steps of primary grouting, primary grout returning, secondary grouting and secondary grout returning, primary grouting material is added during primary grouting, the primary grouting material comprises purple sand mud and water, and the water content of the primary grouting slurry is 20-37.5%; during the secondary grouting, a secondary grouting material is added; the secondary grouting material comprises purple sand mud, water, water glass, sodium carbonate and sodium humate, the water content of the secondary grouting material is lower than that of the primary grouting material and the difference value is 10-15%, the weight of the water glass is 0.1-0.5% of that of the secondary grouting material,the weight of the sodium
