Description

Technical Field

[0001] The present invention relates to the technical field of ceramic production, and in particular to a ceramic tea cup glaze and a production method thereof. Background Art

[0002] Ceramics have a profound cultural heritage in China, dating back to ancient times. With thousands of years of development, they have always been a favorite of scholars and scholars. Their diverse shapes and appearances embody the wisdom and aesthetics of the Chinese nation. However, in modern society, the innovative development of ceramics faces certain difficulties. They are more of a continuation of traditional craftsmanship than a breakthrough innovation, resulting in a relatively narrow audience.

[0003] Currently, the glaze colors and appearance of ceramic tea cups on the market mostly follow the same formulas, processes, and shapes from the Song Dynasty to the Republic of China, with few new breakthroughs. While these traditional glazes possess unique artistic value, they fall short in meeting the increasingly diverse aesthetic demands of the modern public. Furthermore, with increasing environmental awareness, higher demands are being placed on the environmental friendliness of ceramic products. Therefore, developing a ceramic tea cup glaze that both aligns with modern aesthetics and is environmentally friendly is of great practical significance. Summary of the Invention

[0004] The purpose of the present invention is to provide a ceramic tea cup glaze and a production method thereof. The glaze uses 100% raw mineral materials without adding any chemical materials. On the basis of inheriting the intangible cultural heritage technology of ancient handicrafts, combined with the aesthetic needs of the modern public, a ceramic tea cup glaze with a unique appearance and environmentally friendly characteristics is produced, which contributes to the innovative development of Chinese ceramics and makes China's intangible cultural heritage traditional culture shine with new brilliance.

[0005] To achieve the above object, the present invention is implemented through the following technical solutions:

[0006] A ceramic tea cup glaze is made of 100% raw ore materials without adding any chemical materials. The raw ore materials include kaolin iron oxide, loess, quartz, feldspar and calcite. The kaolin iron oxide is taken from Taihang Mountain. The quartz is silicon dioxide with a specific gravity of 2.22-2.65. The feldspar is a silicate mineral and contains silicon oxide, aluminum oxide, potassium oxide, sodium oxide and calcium oxide. The calcite is calcium carbonate.

[0007] Furthermore, the method for making ceramic tea cup glaze comprises the following steps:

[0008] Ingredient preparation: prepare the various raw ore ingredients described in claim 1 according to the formula ratio;

[0009] Ball milling: put all the raw materials into the ball mill in proportion, add appropriate amount of tap water, seal the lid, plug in the power supply, and grind for 18-36 hours;

[0010] Filtration and aging: The polished slurry is filtered through an 80-120 mesh screen, then sealed and aged in an environment of 30 degrees for seven days;

[0011] Glazing and firing: The aged glaze is applied twice to the tea cup blank that has been fired at low temperature, and then placed in the kiln and fired at a high temperature of 1260-1310 degrees. After firing, the temperature is slowly lowered to 60-30 degrees, and the finished ceramic tea cup glaze is obtained after it is taken out of the kiln.

[0012] Furthermore, in the ball milling step, the size and number of the grinding balls are selected according to the characteristics of the raw materials and the capacity of the ball mill to ensure that the raw materials can be fully mixed and ground.

[0013] Furthermore, in the glazing and firing step, the temperature of the bottom-temperature bisque firing treatment is 800-1000 degrees, and the bisque firing time is determined according to the size and thickness of the green body.

[0014] Furthermore, in the glazing and firing step, the glazing method adopts at least one of dipping, spraying or brushing, and the thickness of the glaze layer is uniform during glazing.

[0015] Furthermore, in the glazing and firing step, the temperature is slowly lowered after firing is completed, and the cooling rate is controlled according to the characteristics of the glaze and the requirements of the tea cup.

[0016] Furthermore, the glaze has unique color changes and is made based on the inheritance of ancient handicraft intangible cultural heritage technology and combined with the aesthetic needs of the modern public.

[0017] Beneficial effects of the present invention:

[0018] Environmental protection: This tea cup glaze is made of 100% raw mineral materials without adding any chemical materials. It conforms to the development concept of modern green environmental protection and does not cause any harm to the health of users.

[0019] Innovation: This kind of glaze with unique color changes has not been seen on the market so far. Based on the inheritance of ancient handicraft intangible cultural heritage technology, this glaze combines modern aesthetics to bring a new visual experience to ceramic tea cups.

[0020] Cultural inheritance: The glaze making method of the present invention adopts the ancient raw ore technology, which helps to continue to pass on the ancient handicraft intangible cultural heritage technology and promote the inheritance and development of China's intangible cultural heritage traditional culture. DETAILED DESCRIPTION

[0021] The scheme of the present invention is described in more detail and completely below.

[0022] Specific implementation of a ceramic tea cup glaze and a method for making the same:

[0023] (1) Raw material procurement and preparation

[0024] Kaolin Iron Oxide: We travel to the relevant mineral producing areas in the Taihang Mountains and cooperate with local legal mines to obtain mineral raw materials containing iron oxide. We then conduct preliminary screening of the raw materials to remove impurities.

[0025] Loess: Choose pure, unpolluted loess and perform simple drying and screening processes;

[0026] Quartz: Purchase from a professional quartz supplier and check that its specific gravity is within the range of 2.22-2.65;

[0027] Feldspar: Purchase feldspar mineral raw materials and ensure that they contain appropriate amounts of silicon oxide, aluminum oxide, potassium oxide, sodium oxide, calcium oxide and other components;

[0028] Calcite: Purchase from a reliable calcite supplier and check its purity and particle size.

[0029] (2) Ball milling

[0030] Equipment preparation: Check the operating status of the ball mill to ensure it can work normally, prepare an appropriate amount of grinding balls, and select the appropriate size and quantity of grinding balls according to the characteristics of the raw materials and the capacity of the ball mill;

[0031] Raw material feeding: according to the predetermined formula ratio, put the raw materials such as kaolin iron oxide, loess, quartz, feldspar, calcite into the ball mill in sequence. Pay attention to the accuracy of the feeding sequence and feeding amount to avoid affecting the quality of the glaze due to imbalance of proportions;

[0032] Adding water and ball milling: Add an appropriate amount of tap water to the ball mill. The amount of water should be adjusted according to the characteristics of the raw materials and the requirements of the ball mill. Generally, it is appropriate to enable the raw materials to be fully mixed and ground. Seal the lid of the ball mill, plug in the power supply, start the ball mill, and set the ball milling time to 18-36 hours. During the ball milling process, regularly check the operation of the ball mill to ensure its normal operation.

[0033] (3) Filtration and aging

[0034] Filtration operation: After the ball milling is completed, pour the slurry in the ball mill into the filtration equipment and filter it using an 80-120 mesh screen. During the filtration process, pay attention to controlling the flow rate of the slurry to avoid clogging the screen. The filtered slurry should be collected in a clean container;

[0035] Sealed aging: Seal the filtered slurry and place it in an environment with a temperature of about 30 degrees for aging. The aging time is seven days. During the aging process, check the status of the slurry regularly to ensure that there are no abnormal changes.

[0036] (4) Glazing and firing

[0037] Bisque preparation: Select the appropriate tea bowl blank, and perform bottom temperature biscuiting treatment. The biscuiting temperature and time should be controlled according to the material and requirements of the tea bowl blank. Generally, the biscuiting temperature is between 800-1000 degrees, and the biscuiting time is determined according to the size and thickness of the blank.

[0038] Glazing operation: Apply the aged glaze to the biscuited tea bowl blank in two times. The glazing method can be dipping, spraying, or brushing, etc. According to the shape and requirements of the tea bowl, select the appropriate glazing method. Pay attention to the uniform thickness of the glaze layer during glazing to avoid defects such as glaze flow and glaze leakage.

[0039] Firing process: Place the glazing tea bowl blank into the kiln, and set the firing temperature to 1260-1310 degrees. During the firing process, strictly control the heating rate and firing time to ensure that the glaze can fully melt and react. After firing, slowly cool down to 60-30 degrees, and then take out the tea bowl from the kiln.

[0040] (5) Finished product inspection

[0041] Appearance inspection: Inspect the appearance of the tea bowl taken out of the kiln, and observe whether the color, gloss, and flatness of the glaze surface meet the requirements. Check whether there are defects such as cracks, bubbles, and spots.

[0042] Performance test: Test the performance of the tea bowl, such as acid and alkali corrosion resistance test, wear resistance test, etc. to ensure that its quality meets the relevant standards.
