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 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 neutral or weakly 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 The fourth step is to fire to 1280°C in a neutral or weakly oxidizing atmosphere for 2 hours; the fifth ste...

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-changing glaze: mix 600g copper oxide, 240g calcite, 100g zinc oxide, 50g burnt talc, and 10g tin oxide into a 1kg ball mill jar, add 800g water and process 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: In the first step, fire in a neutral or weakly oxidizing atmosphere for 5 hours to 1050°C; in the second step, fire in a reducing atmosphere for 1 hour to 1120°C; in the third step, fire in a reducing atmosphere for 3 hours The fourth step is to fire to 1300°C in a neutral or weakly oxidizing atmosphere for 2 hours; the fifth step is to cool naturally to roo...

Abstract

The invention discloses a firing method capable of controlling the Jun porcelain furnace transmutation effect. According to the method, a glaze blank with a single color such as sky blue, azure, bluish white, etc. or with a light color and a furnace transmutation glaze material containing copper oxide, calcite, zinc oxide, fired talc and tin oxide are horizontally arranged side by side in a furnace to be fired into a Jun porcelain with a furnace transmutation effect. The method inherits the coloring mechanism of Jun red glaze (cooper is a colorant) in the Jun porcelain and effectively controlsthe Jun porcelain furnace transmutation effect, and the artistic style of natural furnace transmutation is showed.

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...
