Ink painting method for porcelain surface in red glaze

Abstract

The invention discloses an ink painting method for a porcelain surface in a red glaze. The ink painting method comprises the steps of: 1) selecting, cleaning and baking a bone China body; 2) firing the bone China body to prepare a semi-finished product coated by the red glaze at high temperature of 1050-1150 DEG C by adopting the red glaze; 3) blending gelatin, ink and water according to the mass ratio of 2:1:3; soaking the ink and the gelatin for 60 minutes when the temperature of the water is 60 DEG C, grinding for 30 minutes, and storing for 24 hours to prepare basic ink; 4) agitating olibanum oil with camphorated oil according to the volume ratio of 1:1 for 30 minutes to prepare oil; 5) drawing the outline of landscape on the semi-finished product by the basic ink, achieving gradation through adding amount of the oil; and 6) baking the semi-finished product of the drawn pattern at 40 DEG C for 10 minutes after finishing the pattern, heating to 80-100 DEG C to bake for 40 minutes, and then putting into an electrical kiln at 1050-1250 DEG C to fire for 3 hours, carrying out heat preservation for 50 minutes, and naturally cooling to room temperature.

Description

technical field [0001] The invention belongs to a method for painting glazed surfaces of bright red ceramics, and in particular relates to an ink method for porcelain surfaces in bright red glazes. Background technique [0002] Red symbolizes joy and auspiciousness, and is the favorite color of the Chinese nation. For thousands of years, people have always had a puzzled complex with red porcelain. From the ancient crock bean red, Jihong, Langhong, etc., all the way to today's Chinese red, because red is difficult to blend with other colors, it is prone to discoloration after being fired in a kiln, so a small area of ​​other colors is usually used to blend with it. Especially under the in-glaze process, if the same color of pigment is used in a large area, problems such as foaming will easily occur after the pigment penetrates into the glaze layer and cools down. In recent years, researchers have been devoted to the careful study of this project. [0003] The in-glaze proc...

Problems solved by technology

[0007] One is that the bright red glaze contains sulfur and selenium that are active at high temperatures, while the toner mainly contains carbon, and the chemical reaction is not active. However, after a high temperature of 1000 degrees Celsius, the ink color enters the glaze layer and reacts with the red glaze layer. Covered by the red glaze layer, it becomes the underglaze color, which cannot achieve the desired effect
