preparation example Construction

[0021] The invention provides a preparation method of full-glazed Jun porcelain spherical glaze beads, comprising the following steps:

[0022] a) In parts by weight, mix 42 to 48 parts of yellow feldspar, 18 to 22 parts of potassium feldspar, 13 to 18 parts of quartz, 4 to 6 parts of talc and 13 to 18 parts of calcite, ball mill to obtain a glaze slurry, pass 120 Mesh sieve, after drying, grind into powder, add water, and make the glaze mud into balls to obtain glaze balls;

[0023] b) Place a corundum plate covered with ultra-fine alumina micropowder on the shed plate as the setter plate, disperse the glaze balls on the setter plate, and use the method of first oxidation and then reduction for glaze firing, the temperature of glaze firing The temperature is 1260~1300℃, and the spherical glaze beads of full-glazed Jun porcelain are obtained.

[0024] The method provided by the present invention uses the above-mentioned amount of raw materials to directly prepare glaze balls,...

Embodiment 1

[0044] 1. Bottom glaze: Mix 45 parts by weight of yellow feldspar, 20 parts by weight of potassium feldspar, 15 parts by weight of quartz, 5 parts by weight of talc, and 15 parts by weight of calcite according to the proportion, add an appropriate amount of water, and place Mill in a ball mill for 12 hours, then pass the glaze slurry through a 120-mesh sieve, and the sieve balance is less than 0.5%; dry the glaze slurry that has been ball-milled naturally in the sun, and grind it into powder; directly add a small amount of water to moisten the glaze mud. Process it into a glaze ball with a diameter of 2 cm and let it dry.

[0045] 2. Glaze firing device: use a smooth and flat corundum plate as the firing plate, and spread a layer of ultrafine alumina powder with a thickness of 0.5 mm on it, and disperse the glaze balls on the alumina powder.

[0046] 3. Glaze firing: firing with the firing system of first oxidation and then reduction, the firing temperature is 1260-1300°C, an...

Embodiment 2

[0049] 1. Bottom glaze: Mix 45 parts by weight of yellow feldspar, 20 parts by weight of potassium feldspar, 15 parts by weight of quartz, 5 parts by weight of talc, and 15 parts by weight of calcite according to the proportion, add an appropriate amount of water, and place Mill it in a ball mill for 12 hours, then pass the glaze slurry through a 120-mesh sieve, and the sieve residue is less than 0.5%. Dry the glaze slurry that has been ball-milled naturally in the sun, and grind it into powder; directly add a small amount of water to the glaze powder to wet it into glaze mud; process the glaze mud into a glaze ball with a diameter of 2cm, to dry.

[0050] 2. Top glaze configuration: The top glaze is sky blue colored top glaze. Mix 55 parts by weight of feldspar, 15 parts by weight of quartz, 14 parts by weight of kaolin, 15 parts by weight of calcite and 1 part by weight of iron ore according to the proportion, add an appropriate amount of water, and place in a planetary bal...

Abstract

The invention provides a preparation method of full-glazed Jun porcelain spherical glaze beads, comprising: a) by weight parts, 42-48 parts of yellow feldspar, 18-22 parts of potassium feldspar, 13-18 parts of quartz, 4- Mix 6 parts of talc and 13-18 parts of calcite, ball mill to obtain glaze slurry, pass through a 120-mesh sieve, dry it, grind it into powder, add water, and make the obtained glaze mud into balls to obtain glaze balls; b) Place on the shelf The corundum plate covered with ultra-fine alumina micropowder is the setter plate, the glaze balls are dispersed on the setter plate, and the glaze is fired at 1260-1300°C in the way of first oxidation and then reduction, and the spherical glaze beads of full-glazed Jun porcelain are obtained. The method provided by the invention can prepare full-glazed Jun porcelain spherical glaze beads, which have a high degree of vitrification, good kiln transformation effect of the glaze material, and glow brightly under sunlight. The glaze beads are easy to take out, the glaze does not flow, and it does not stick to the firing board and shed board. This method does not use the green body, reduces bisque firing procedures, and reduces the refraction of light by the green body.

Description

technical field [0001] The invention relates to the technical field of glazed porcelain, in particular to a full-glazed Jun porcelain spherical glaze bead and a preparation method thereof. Background technique [0002] Jun Porcelain is one of the five famous kilns in Song Dynasty. Traditional Jun porcelain is mainly in the shape of vase, tripod, and Zun. 30 cm or more. As people's love for Jun porcelain has been escalating, Jun porcelain toy pieces have gradually become popular. The 5-10 cm tall Jun porcelain tea sets, saucers, etc., are very popular because of their simple shape and warm glaze color. [0003] However, these Jun wares are basically not full-glazed Jun wares, usually without glaze on the fired bottom. Affected by Jun porcelain technology and the high-temperature fluidity of glaze, it is difficult to produce full-glazed Jun porcelain. Because the firing of Jun porcelain requires a high temperature of 1200°C-1300°C, the glaze surface of Jun porcelain flows...
