Problems solved by technology

However, the conditions required by these atmospheres are extremely difficult to control, so there is a saying that "ten kilns fail nine times" when firing Jun porcelain, "three points depend on the shape of the vessel, five points depend on firing, and two points depend on luck". Jun porcelain is very difficult

Embodiment 1

[0022] 1. Glaze embryo selection: use the moon white glaze as the carrier, dry the glaze embryos with the moon white glaze applied to the kiln.

[0023] 2. Selection and processing of kiln glaze: 500g of copper oxide, 300g of calcite, 150g of zinc oxide, 30g of burnt talc, and 20g of tin oxide are mixed and put into a 1kg ball mill jar, and then processed with 800g of water for 30 hours to obtain a particle size of 250 mesh. Glaze, and placed in a crucible to dry.

[0024] 3. Place the crucible containing the dried kiln-transformed glaze and the Jun porcelain glaze blank that needs to have a kiln-transformed effect horizontally.

[0025] 4. Firing method: In the first step, fire in a weak oxidizing atmosphere for 3 hours to 950°C; in the second step, fire in a reducing atmosphere for 2 hours to 1080°C; in the third step, fire in a reducing atmosphere for 4 hours to 1180°C ℃; the fourth step, firing in a weakly oxidizing atmosphere for 2 hours to 1280°C; the fifth step, coolin...

Embodiment 2

[0027] 1. Glaze embryo selection: use the sky blue glaze as the carrier, dry the glaze embryo with the sky blue glaze and put it in the kiln.

[0028] 2. Selection and processing of kiln glaze: 600g of copper oxide, 240g of calcite, 100g of zinc oxide, 50g of burnt talc, and 10g of tin oxide are mixed and put into a 1kg ball mill jar, and then processed with 800g of water for 30 hours to obtain a particle size of 250 mesh. Glaze, and placed in a crucible to dry.

[0029] 3. Place the crucible containing the dried kiln-transformed glaze and the Jun porcelain glaze blank that needs to have a kiln-transformed effect horizontally.

[0030] 4. Firing method: first step, firing to 1050°C for 5 hours in a weak oxidizing atmosphere; second step, firing to 1120°C for 1 hour in a reducing atmosphere; third step, firing to 1220°C for 3 hours in a reducing atmosphere ℃; the fourth step, firing in a weakly oxidizing atmosphere for 2 hours to 1300°C; the fifth step, cooling naturally to ro...

Embodiment 3

[0032] 1. Glaze embryo selection: use the sky blue glaze as the carrier, dry the glaze embryo with the sky blue glaze and put it in the kiln.

[0033] 2. Selection and processing of kiln glaze: 560g of copper oxide, 260g of calcite, 125g of zinc oxide, 40g of burnt talc, and 15g of tin oxide are mixed and put into a 1kg ball mill jar, and processed for 30 hours with 800g of water to obtain a particle size of 250 mesh. Glaze, and placed in a crucible to dry.

[0034] 3. Place the crucible containing the dried kiln-transformed glaze and the Jun porcelain glaze blank that needs to have a kiln-transformed effect horizontally.

Abstract

The invention discloses a firing method with controllable kiln transformation effect of Jun porcelain, which is to combine sky blue, sky blue and moon white glaze embryos with kiln transformation glaze materials containing copper oxide, calcite, zinc oxide, burnt talc and tin oxide. Placed side by side horizontally in the kiln, they are fired into Jun porcelain with kiln transformation effect. This method inherits the color formation mechanism of Jun red glaze (copper is the coloring agent) in Jun porcelain, effectively controls the kiln transformation effect of Jun porcelain, and shows the artistic style of natural kiln transformation.

Description

technical field [0001] The invention relates to the field of kiln transformation of Jun porcelain, in particular to a firing method capable of controlling the kiln transformation effect of Jun porcelain. Background technique [0002] Jun porcelain is known as one of the "five famous porcelains" of the Song Dynasty in China for its magical kiln transformation of "one color when entering the kiln, and thousands of colors when leaving the kiln". Jun porcelain kiln transformation is a very magical ceramic art effect. The general Jun porcelain glaze is made by adding minerals containing copper and iron to the basic glaze, and firing in an atmosphere of oxidation first and then reduction. However, the conditions required by these atmospheres are extremely difficult to control, so there is a saying that "ten kilns fail nine times" when firing Jun porcelain, "three points depend on the shape of the vessel, five points depend on firing, and two points depend on luck". Jun porcelain...
