preparation example Construction

[0030] The preparation technology of purple-colored green-dot kiln-transformed porcelain is characterized in that the specific steps are as follows:

[0031] Step 1, preparing a ceramic green body;

[0032] Step 2: Proportionally weigh the raw material components of the purple-colored green-dot kiln-changing glaze, perform wet ball milling on the raw materials of the purple-colored green-dot kiln-changing glaze, pass through a 500-600 mesh sieve after ball milling, and obtain the colorful green-dot kiln-changing glaze. Feldspar, quartz, fluorite, rutile, spodumene, dolomite, and ashes are pulverized into powder materials, and the powder materials together with a high expansion coefficient co-solvent are put into a wet ball mill and mixed for 3-4 hours, and titanium, lead Dan, zinc, iron oxide, calcium, and dispersant are mixed and stirred, then added to the wet ball mill, and continue to mix for 1-2 hours. The mass ratio of ball: water: 1-2:1-1.5:2 for the glaze of the wet bal...

Abstract

The invention belongs to the field of ceramic products, and particularly relates to purple green dot kiln-transmutation porcelain and a preparation process thereof. An additive containing calcium, titanium and low-valence iron is added into alkaline glaze; the principle that titanium has a purple red color in alkaline glaze is taken as the basis, green crystallization spots are formed by calcium and low-valence iron; the substrate has a purple red color, the purple red color has a transition effect and a changing kiln-transmutation effect, and green spots with a diameter of 1-3 mm are uniformly distributed on the purple red color. The characteristic of a traditional multi-color kiln-transmutation glaze material is broken through, the comparison between purple and the green is significant,and a unique artistic effect is achieved. The used raw materials are environmentally friendly. One-time firing and forming can be achieved after twice temperature changing and changing of a firing atmosphere. The production cost of raw materials is effectively reduced, meanwhile, the firing temperature is low, the environment-friendly value is high, and economic benefits and market competitivenessare improved.

Description

technical field [0001] The invention belongs to the field of ceramic products, and in particular relates to a purple-colored green-dot kiln-transformed porcelain and a preparation process thereof. Background technique [0002] Ceramic products are widely used in our country, and the technology for preparing ceramics is also very mature. Kiln change mainly refers to the uncertain and natural change of glaze color on the surface of porcelain due to the temperature change in the kiln during the firing process, and the kiln change glaze produced has a unique visual effect. During the preparation process of the traditional kiln-transformed glaze, the requirements for the use of raw materials and the preparation process are relatively high. The kiln-transformed glaze ceramic products produced by a little carelessness have poor visual effects and poor appreciation, and cannot meet the requirements of the market. [0003] For example, the application number is CN201811469328.2, whi...
