Embodiment 1

[0016] Embodiment 1: the preparation method of golden yellow metallic luster glaze

[0017] (1) The following various raw materials are first made into frits by weight percentage:

[0018] Quartz 10-20%, lepidolite 40-60%, boric acid 10-20%, barium carbonate 2-6%, limestone 3-10%, titanium dioxide 1-3%, iron oxide 0.3-1.5%.

[0019] After mixing the above raw materials evenly, it is melted at 1200-1350 ° C, and after water quenching, a light yellow frit is obtained.

[0020] (2) make glaze by following weight percentage:

[0021] Light yellow frit 75-85%, high boron frit 5-15%, mica titanium 1-4%, kaolin 4-8%.

Embodiment 2

[0022] Embodiment 2: the preparation method of silver-white metallic luster glaze:

[0023] (1) The following various raw materials are first made into frits by weight percentage:

[0025] After mixing the above raw materials evenly, it is fired at 1250-1350°C to form a white frit.

[0026] (2) Make the glaze according to the following weight percentage

[0027] White frit 80-95%, high-boron frit 0-15%, kaolin 4-8%.

Embodiment 3

[0028] Embodiment 3: the preparation method of bright blue-gray metallic luster glaze:

[0029] (1) The following various raw materials are made into frit by weight percentage:

[0030] Quartz 15-25%, lepidolite 30-40%, boric acid 5-10%, barium carbonate 2-6%, limestone 5-15%, zinc oxide 3-8%, cerium oxide 2-6%, molybdenum trioxide 2 ~5%, manganese dioxide 0.3~0.8.

[0031] Mix the above raw materials evenly and melt them at 1250-1350°C to form a light blue frit.

[0032] (2) Make the glaze according to the following weight percentage

Abstract

The invention provides a production method for a colorful, color-stable imitated metallic luster glaze which can meet the requirements of low-temperature rapid firing process. The method includes: (1) first making the following raw materials into a frit by weight percentage of 10-20 per cent quartz, 40-60 per cent lepidolite, 10-20 per cent boric acid, 2-6 per cent barium carbonate, 3-10 per cent limestone, 3-12 per cent metal oxide and then evenly mixing the raw materials after melting at 1200-1350 DEG C and obtaining a color frit by water quenching. (2) making the glaze with the following materials by weight of 75-90 per cent color frit, 0-20 per cent high boron frit and 5-10 per cent kaolinite. The metallic luster glaze products is colorful and low in sintering temperature and is suitable for the characteristics and style of interior wall glazed tiles of twice low-temperature rapid firing and the frit is produced by sintering metal oxides, therefore the color is very stable.

Description

Technical field: [0001] The invention relates to the technical field of imitation metal glaze production. The prepared metal glaze is applied on the ceramic biscuit, and the product after low-temperature rapid firing has a decorative effect similar to metallic luster. Background technique: [0002] At present, the production methods of metal glaze are as follows: [0003] 1. The method of glaze thermal spraying, which makes the mixed metal salt melt decompose on the hot glaze surface to form a metal film layer, which has a rainbow-like luster. The disadvantage is that the price of glaze is higher, and the production process is complicated, which is difficult to control in mass production. [0004] 2. Gold water and silver water made of organic oils, bismuth compounds, gold chloride (platinum chloride), etc. can give very good luster and gorgeous gold and silver colors. The disadvantage is that the firing temperature is low (600-800°C), which is only suitable for handicraf...
