Embodiment 1

[0018] Such as figure 1 As shown, the steps include engraving on the green body, filling mud for the first time, drying, filling mud for the second time, drying and firing. The mud used for the first mud filling is colored soil and titanium dioxide powder in a mass ratio of 100 The ratio of :8 is adjusted to mix, and the mud used for the second mud filling is colored soil, titanium dioxide powder and table salt and adjusted to mix in a ratio of 100:1:2 by weight. The first mud filling is to fill the mud into the groove carved in the body without filling the groove. The second mud filling is to fill the mud into the groove carved in the body, and the first time to fill the mud At the same time, the thickness of the mud for the second filling is 0.3mm.

[0019] The first drying time is 6 days and the second drying time is 22 days.

[0020] The firing temperature of the first stage of firing is 1185°C and the firing time is 6.5 hours; the firing temperature of the second stage ...

Embodiment 2

[0022] The difference from Example 1 is that the mud used for the first mud filling is colored soil and titanium dioxide powder, which is mixed in a ratio of 100:6 by mass, and the mud used for the second mud filling is colored soil, titanium dioxide powder The powder and table salt are adjusted and mixed in a ratio of 100:2:2 by weight. The thickness of the mud for the second mud filling is 0.5mm.

[0023] The first drying time is 5 days and the second drying time is 25 days.

[0024] The firing temperature of the first stage of firing is 1200°C and the firing time is 6 hours; the firing temperature of the second stage is 1135°C and the firing time is 4 hours. After firing, keep warm for 25 minutes.

Embodiment 3

[0026] The difference from Example 1 is that the mud used for the first mud filling is colored soil and titanium dioxide powder mixed in a ratio of 100:5 by mass, and the mud used for the second mud filling is colored soil and titanium dioxide powder. Mix it with table salt in a ratio of 100:3:2 by weight. The thickness of the mud for the second mud filling is 0.3mm.

[0027] The first drying time is 10 days, and the second drying time is 20 days.

[0028] The firing temperature of the first stage of firing is 1200°C and the firing time is 6.5 hours; the firing temperature of the second stage is 1130°C and the firing time is 3 hours. After firing, keep warm for 30 minutes.

Abstract

The invention relates to a making and mud filling method of ceramic, in particular to a multi-layer mud filling method of Nixing ceramic. The multi-layer mud filling method comprises the following steps: engraving on a green body, performing first mud filling, drying, performing second mud filling, drying and firing; pug used for the first mud filling is mixed from colored clay and titanium dioxide powder according to the weight ratio of 100:(5-8); pug used for the second mud filling is mixed from colored clay, titanium dioxide powder and table salt according to the weight ratio of 100:(1-3):(1-2). The Nixing ceramic prepared by the multi-layer mud filling method provided by the invention is higher in rate of finished products and has higher artistic values.

Description

technical field [0001] The invention relates to a ceramic manufacturing and mud filling method, in particular to a Nixing pottery multilayer mud filling method. Background technique [0002] Nixingtao's mud filling technology generally adopts a single-layer mud filling method, which has a relatively high yield and is generally accepted by the industry. [0003] The comparative patent "Filling method of Nixing pottery" (Application No.: 201510004427.3) discloses a method for filling mud of Nixing pottery, including blank preparation, blank molding, painting, carving, mud filling, drying and firing processes. The mud filling is to adjust the colored soil and titanium dioxide powder into a mixed soil with a weight ratio of 100:2~8, fill it into the carved groove, and then flatten and compact it. The drying is to seal the mud-filled body with a plastic film, and let it dry naturally for 25 to 35 days. The firing is to tear off the plastic film from the dry body and then instal...
