Problems solved by technology

[0002] Ceramic pots are usually glazed and fired after applying a kind of enamel. The color of the made ceramic pot is single and not beautiful enough.
To make the surface of the ceramic pot have different colors, if different colors of enamel are applied, the enamel is likely to melt into each other, and there is no clear dividing line for the color of the enamel, so the effect of the finished product is not satisfactory.

Embodiment 1

[0019] Example 1: (1) After the porcelain clay is molded into a ceramic pot body through conventional ingredients, ball milling, sieving, dehydration, aging, smelting, and grouting in the ceramic production process, it is then bisque fired at 750°C for 5 hours;

[0020] (2) Mix 20% of gasoline and 80% of wax by weight percentage, and heat to 60°C to make spacer fluid for later use;

[0021] (3) According to weight percentage, 6% alumina, 42.973% petalite feldspar, 16% quartz, 8% talc, 6% calcium oxide, 9% kaolin, 9% feldspar, 0.004% rhodium, 0.015% nickel, tungsten 0.005%, molybdenum 0.003%, iron oxide 3%, after mixing, put it into a ball mill, add clear water, the weight ratio of the above mixed materials and clear water is 1:1, and the slurry passed through the ball mill passes through a 325 mesh sieve to make an inner glaze for later use;

[0022] According to weight percentage, alumina 6%, petalite feldspar 42.939%, quartz 16%, talc 8%, calcium oxide 6%, kaolin 9%, feldspa...

Embodiment 2

[0025] Example 2: The difference from Example 1 is that in the step (4), after immersing the ceramic pot body in the outer glaze for glazing and drying it, first place the ceramic pot body in a -6°C freezer for 6 minutes, and then put the Place the ceramic pot body in an oven at 25°C for 6 minutes; then place the ceramic pot body in a -18°C freezer for 12 minutes, then place the ceramic pot body in an oven at 45°C for 12 minutes, and finally enter the step ( 5) production process, the product of embodiment 2 is obtained. The glaze texture of the product of Example 2 is firmer, and the glaze surface is scratched with a paper cutter, without leaving any knife marks, and the glossiness is better than that of the product of Example 1.

Abstract

The invention discloses a method for quickly producing a porcelain pot with different colors on the inner surface and the outer surface. The method is characterized by comprising the following steps of: 1, carrying out slip casting to form a porcelain pot blank and then biscuiting the porcelain pot blank; (2), preparing spacer fluid for later use; (3), preparing an internal glaze for later use, preparing an external glaze for later use; (4), glazing an inner cavity of the porcelain pot blank, then wiping excessive internal glaze off by using wet cloth, brushing the spacer fluid on the surface of the internal glaze, integrally immersing the porcelain pot blank in the external glaze for glazing; and (5), carrying out glaze firing on the porcelain pot blank subjected to glazing of the internal glaze and the external glaze to obtain the porcelain pot. The porcelain pot with different colors on the inner surface and the outer surface is produced by regulating components and proportion of pigments in the glazes, a boundary at the junction of the internal glazing surface and the outer glazing surface is clear and obvious, and no blending exists between the internal glaze and the external glaze; and the method is low in production cost, short in period and convenient in production.

Description

technical field [0001] The invention relates to the field of ceramics, in particular to a rapid production method of ceramic pots with different colors on the inner and outer surfaces. Background technique [0002] Ceramic pots usually all apply a kind of enamel and then burn the glaze, the color of the ceramic pots made is single, not attractive enough. To make the surface of the ceramic pot have different colors, if different colored glazes are applied, the phenomenon of mutual fusion between the glazes will easily occur. There is no clear dividing line for the colors of the glazes, and the effect of the finished product is not satisfactory. Contents of the invention [0003] In order to overcome the above disadvantages, the present invention provides a rapid production method of ceramic pots with different colors on the inner and outer surfaces. [0004] A rapid production method of ceramic pots with different colors on the inner and outer surfaces, characterized in t...
