Detailed Description
For a further understanding of the present invention, the present invention is described below in conjunction with the following examples, which are provided to further illustrate the features and advantages of the present invention and are not intended to limit the claims of the present invention.
The invention discloses a blue pattern Jin Banhua glaze, which comprises the following preparation raw materials in parts by mass: 20-40 parts of feldspar, 10-21 parts of quartz, 10-30 parts of kaolin, 1-4 parts of cobalt black, 6-10 parts of ferric oxide, 0.2-0.8 part of sodium tripolyphosphate and 0.5-1.5 parts of sodium carboxymethyl cellulose. The blue-grain golden-spot fancy glaze fired by the glaze formula is wholly black and blue, and rose-shaped golden spots are distributed on the surface of the glaze. The blue glaze is a glass phase, and the golden speckles are caused by that yellow dendritic crystals are separated out from the glaze and coated with reddish brown snowflake crystals. The size of the speckles can be controlled according to the accurate raw material proportion and the thickness of the glaze layer. Meanwhile, the firing of the blue-grain golden-spot fancy glaze needs to ensure a strict firing system, and the invention details firing temperature control information of the fancy glaze, provides guarantee for batch and industrialized production of the blue-grain golden-spot artistic fancy glaze, reduces the cost and increases the efficiency, and has market competitiveness.
The preparation process of the blue-grain golden-spot fancy glaze specifically comprises the following steps of:

When the concentration (solid content) of the glaze reaches 60%, the glaze is sieved by a sieve with 80 meshes and 150 meshes to obtain the glaze with the blue-grain golden spot fancy glaze with uniform and fine texture.
(2) Dipping the biscuit after the biscuit firing in glaze for 5-15s, and drying overnight at room temperature after the glazing thickness reaches 1-3 mm.
(3) The firing system of the blue pattern golden spot fancy glaze is as follows: the temperature rise rate is 5 ℃/min at 25 ℃ to 300 ℃; 300-900 ℃, and the heating rate is 3 ℃/min; 900-1280 ℃, the heating rate is 1.5 ℃/min, the temperature is kept for 30min after the temperature is increased to 1280 ℃, and the temperature is reduced to the room temperature along with furnace cooling after firing.
