Method for manufacturing sharp spine-shaped projections on ceramic

Abstract

The present invention relates to a pottery tipping method as a pottery decoration method in a pottery manufacturing method, which is characterized in that the method includes: a protrusion forming step: when the pottery formed by the conventional method is still in a semi-dry state, use Applying the first slurry on the outer surface of the utensil with a coarse brush to form a plurality of convex roots; and, the step of growing protrusions: using a coarse brush to repeatedly apply the second slurry for 50 -100 times, and every time you apply it, put it in a cool place to dry for 15-25 minutes at a temperature of 15-20°C and a relative humidity of 60-70%, so that the protrusions grow. The present invention adjusts the protrusion density through the first mud, adjusts the protrusion size through the application times of the second mud, and properly selects the application direction and the pigment mixed in the mud, thereby evolving protrusions with various shapes and colors Group, to achieve a variety of ceramic patterns that could not be achieved by previous techniques.

Description

technical field [0001] The present invention relates to a ceramic ware tipping method, in particular to a method for decorating ceramic ware in a ceramic ware manufacturing method, that is, a method for forming needle-shaped protrusion groups on the outer surface of the ware. Background technique [0002] Generally speaking, the manufacture of ceramics must successively go through the steps of water shaking, mud mixing, molding, decoration, primary firing, glazing, and secondary firing. [0003] The above water winnowing step is the step of uniformly pulverizing the soil (raw material) and mixing it into water, placing the mud on a sieve to remove impurities, extracting the precipitate and placing it in a cool place for drying. The above-mentioned mixing clay step is a step of adding an appropriate amount of water to the above-mentioned dried pottery clay, and kneading the pottery clay with hands and feet or a wooden mallet. Here, the pottery clay must be fully mixed to mak...

Problems solved by technology

[0012] However, the above-mentioned first technology of forming protrusions on the outer surface of ceramics by changing the glaze composition ratio is not only not obvious enough to form protrusions, but also cannot obtain various styles; The pressure is raised, which has the effect of finger pressure, but it will reduce the aesthetic feeling and weaken the desire of consumers to buy
