Example Embodiment

[0021] Example one:

[0022] Example 1 is the best implementation plan, which is a base glaze plan suitable for daily-use ceramic stoneware and white porcelain. The specific technical plan is described as follows:

[0023] The formula does not contain crystalline and phase-separating materials such as zinc oxide and titanium dioxide. It uses feldspar, quartz, calcite, talc, and kaolin as the base glaze material. The silicon-to-aluminum ratio is 6.1. It is matched with appropriate calcium and magnesium materials to increase gloss and melting. Effect, with iron red and manganese carbonate to form a black-brown background color, to ensure that the solution can liberate gas through high temperature decomposition to form many dense small bubbles, forming defects on the surface of the base glaze, and then equipped with a suitable top glaze. The proportion by weight of the base glaze is:

[0024] Feldspar: 45 parts Quartz: 20 parts Calcite: 15 parts Talc: 5 parts

[0025] Kaolin: 10 parts I...

Abstract

The invention relates to a multicolor furnace transmutation glaze ground coat and a manufacturing method thereof. The manufacturing method comprises the step of adding a part of chromogenic oxides into feldspar, quartz, calcite, talc and kaolin which are selected as ground coat raw materials. Moreover, the ratio of silicate to aluminium of the ground coat must be over six, so that solution can be decomposed at high temperature to release gas to form a plurality of fine and dense small bubbles and defects are formed on the surface of a glaze layer; and then suitable cover glazes are matched to generate various furnace transmutation effects. According to a process formula of the glaze of the ground coat, the multicolor furnace transmutation glaze ground coat comprises the following components in part by weight: 45 parts of feldspar, 18 to 25 parts of quartz, 12 to 18 parts of calcite, 2 to 5 parts of talc, 5 to 12 parts of kaolin, 10 to 14 parts of iron oxide red and 2 to 5 parts of manganese carbonate. The ground coat prepared according to the process formula comprises the following chemical compositions: 58 to 64 percent of SiO2, 8 to 11 percent of Al2O3, 7 to 9.8 percent of CaO, 0.4 to 1.6 percent of MgO, 4 to 5.8 percent of K2O, 0.9 to 1.2 percent of Na2O, 9 to 13 percent of Fe2O3 and 0.9 to 2.3 percent of MnO.

Description

technical field [0001] The invention relates to a daily-use ceramic glaze and a production method thereof, in particular to a bottom glaze suitable for daily-use ceramics and decorative art ceramics and a production method thereof. The glaze is a bottom glaze capable of producing various kiln transformation effects. The invention belongs to the technical field of ceramic glazes of inorganic non-metallic materials. Background technique [0002] Kiln-changing glaze is a general term for art glazes that produce kiln-changing effects during the firing process of ceramic glazes. The invention belongs to the technical field of ceramic glazes of inorganic non-metallic materials, and is used for the entire glaze surface and partial decoration of daily-use ceramics and art ceramics. Kiln variable glazes are divided into single-layer, double-layer and multi-layer kiln variable glazes, among which single-layer kiln variable glazes include zinc silicate crystal glaze, titanium silicate...
