Problems solved by technology

[0004] However, during the actual production of the glaze in the above-mentioned technical solution, the inventors observed that the cadmium carbonate used as a flux in the glaze is highly toxic and irritating, requiring storage environment and processing environment. They are all very high, which increases the glaze processing cost to a certain extent, and it is inevitable that some cadmium compounds and cadmium dust will leak during processing, which brings potential harm to the health of operators.

Embodiment 1

[0026] A bright red glaze for ceramics, comprising the following components by weight: 30 parts of potassium feldspar, 18 parts of quartz, 6 parts of marble, 8 parts of kaolin, 6 parts of transparent frit, 50 parts of water, and 2 parts of scarlet material , 1 red coral stone powder.

[0027] Its preparation method is as follows:

[0028] Step 1, the red coral stone is crushed and then ball-milled, and the powder obtained after ball milling is passed through a 325-mesh standard sieve to obtain the red coral stone powder for subsequent use;

[0029] Step 2, mix 30 parts of potassium feldspar, 18 parts of quartz, 6 parts of marble, 8 parts of kaolin, 6 parts of transparent frit, and 50 parts of water, and then ball-milled into glaze slurry. The 10,000-gauss iron remover removes iron 3 times, and the glaze paste passes through a 325-mesh standard sieve;

[0030] Step 3, mix 2 parts of the bright red material and 1 part of the red coral stone powder evenly and ball-mill into a p...

Embodiment 2

[0033] A bright red glaze for ceramics is composed of the following components by weight: 50 parts of potassium feldspar, 38 parts of quartz, 13 parts of marble, 15 parts of kaolin, 10 parts of transparent frit, 70 parts of water, and 8 parts of scarlet material , 3 parts of red coral stone powder.

[0034] Its preparation method is as follows:

[0035] Step 1, the red coral stone is crushed and then ball-milled, and the powder obtained after the ball milling is passed through a 380-mesh standard sieve to obtain the red coral stone powder for subsequent use;

[0036] Step 2: Mix 50 parts of potassium feldspar, 38 parts of quartz, 13 parts of marble, 15 parts of kaolin, 10 parts of transparent frit, and 70 parts of water, and then ball-milled into a glaze slurry. The ball-milling time is 19h. The 10,000-gauss iron remover removes iron 5 times, and the glaze paste passes through a 380-mesh standard sieve;

[0037] Step 3, mix 8 parts of the bright red material and 3 parts of t...

Embodiment 3

[0040] A bright red glaze for ceramics, comprising the following components by weight: 45 parts of potassium feldspar, 30 parts of quartz, 10 parts of marble, 13 parts of kaolin, 9 parts of transparent frit, 65 parts of water, and 6 parts of scarlet material , 2.5 parts of red coral stone powder.

[0041] Its preparation method is as follows:

[0042] Step 1, the red coral stone is crushed and then ball-milled, and the powder obtained after the ball milling is passed through a 380-mesh standard sieve to obtain the red coral stone powder for subsequent use;

[0043] Step 2: Mix 45 parts of potassium feldspar, 30 parts of quartz, 10 parts of marble, 13 parts of kaolin, 9 parts of transparent frit, and 65 parts of water, and then ball-milled into a glaze slurry. The ball-milling time is 18h. The 10,000-gauss iron remover removes iron 4 times, and the glaze slurry passes through a 380-mesh standard sieve;

[0044] Step 3, mix 6 parts of the scarlet material and 2.5 parts of the ...

Abstract

The invention discloses a large red glaze for ceramics and a preparation method thereof, and relates to the technical field of ceramic glazes. The large red glaze for ceramics is composed of the following components in parts by weight: 30-50 parts of potassium feldspar, 18-38 parts of quartz , 6-13 parts of marble, 8-15 parts of kaolin, 6-10 parts of transparent frit, 50-70 parts of water, 2-8 parts of scarlet material, 1-3 parts of red coral stone powder; use red coral stone powder instead Cadmium carbonate is used as a flux, because the main component of red coral stone powder is CaCO 3 Therefore, the storage environment requirements of the red coral stone powder are low, the storage cost of the raw material is saved, and the red coral stone powder itself has the red property, so the use of the bright red material is also reduced in the present invention, and the cost is further reduced; Since the cadmium carbonate is replaced by the red coral stone powder, the present invention does not produce toxic substances such as cadmium compounds and cadmium dust during the processing, further improving the quality of the processing environment and ensuring the health of the operators.

Description

technical field [0001] The invention relates to the technical field of ceramic glazes, in particular to a large red glaze for ceramics and a preparation method thereof. Background technique [0002] The red in Chinese red porcelain means peace, auspiciousness, joy, fortune, prosperity, longevity, dignity, harmony, reunion, success, etc. It has rich cultural connotations and a lofty spiritual realm. With the continuous advancement of technology, Chinese red gradually Applied to daily utensils, the red porcelain, which could only be enjoyed by the royal family in ancient times, gradually entered our modern life. [0003] In the Chinese patent with the authorization announcement number CN102491794B, a bright red glaze for ceramics is disclosed, which consists of 30-50 parts of potassium feldspar, 20-40 parts of quartz, 5-15 parts of marble, 8-15 parts of kaolin, and transparent frit. 6-10 parts, 0.1-0.5 parts of cadmium carbonate, 4-12 parts of bright red material and 50-70 pa...
