Problems solved by technology

From the perspective of glaze ratio, chemical hair coloring agents are cheap and easy to obtain, but the effect of the Tianmu glaze produced is far from that of the original ore glaze. Fluidity; From the point of view of the firing process, this kind of red Yaobian Tianmu ceramics uses ferric oxide as the main coloring agent, so it must be fired in an oxidizing flame atmosphere, otherwise when the kiln temperature reaches above 1000°C, It begins to d

Example Embodiment

[0038] Examples:

[0039] The preparation process of erythema oil dripping Tianmu glaze ceramics on black background is as follows:

[0040] Step 1. According to the raw material formula composition of the iron tire body, the raw materials are wet-ground in a ball mill to make the iron tire body slurry;

[0041] Step 2. The grinded iron tire body slurry is passed through a 150-mesh sieve, dehydrated, and dried to form an iron tire body;

[0042] Step 3, according to the formula composition of the erythema oil drop glaze raw materials, the raw materials are wet-ground in a ball mill and then passed through a 180-mesh sieve to make the erythema oil drop glaze;

[0043] Step 4. The iron tire blank in step 2 is sintered at 620℃ to make an iron tire blank. The moisture content of the iron tire blank is 1.5%. Apply the red spot oil drop glaze made in step 3 on the iron tire blank When applying the glaze, the Baume meter concentration of the erythema oil drip glaze is 58 degrees, and the glaz...

Abstract

The invention belongs to the field of ceramic products, and particularly relates to black-base red-speckle oil-drop temmoku glaze ceramic and a preparing process thereof. The ceramic includes an iron matrix blank and a red-spotted oil-drop glaze material. According to the ceramic and the method, the fired ceramic has a purple black matrix, the red-spotted oil-drop glaze material shows dark red speckles from inside to outside, crystallized particles are preserved in a glaze layer, and a flowing sense during high-temperature molding of the glaze can be observed obviously when the ceramic is observed with a magnifying lens. During firing, a reducing atmosphere is used and nitrogen is fed during firing to perform a reaction, and elements in the red-spotted oil-drop glaze material and the iron matrix blank are extracted to help combustion so that glaze raw materials are changed and recombined. The ceramic has beautiful colors, warm and humid hand feel, and high value of appreciation and artistic value.

Description

technical field [0001] The invention belongs to the field of ceramic products, in particular, the invention relates to a kind of ceramics with erythema on a black background and a celestial eye glaze ceramic and a preparation process. Background technique [0002] Tianmu glaze, which was created and fired in the Song Dynasty, is one of the special varieties of black glaze. It is characterized by the formation of dot-shaped crystals with metallic luster in different sizes in the black glaze layer of the bowl. The diameter of the large one is several millimeters, and the small one is only The size of a needle tip, there are golden yellow and silver white metallic luster dots, that is, like stars twinkling in the night sky, very like drops of crystal oil drops, hence the name "oil drop glaze". [0003] There are countless crystalline spots of different sizes unevenly protruding on the black glaze surface of the kiln. Those with a color like gold are called "golden oil drops", t...
