Description

Technical Field

[0001] This invention relates to the field of Zisha clay technology, and more specifically to a Zisha clay rich in trace elements and its preparation method. Background Technology

[0002] Zisha (purple clay) is a type of ceramic ware that falls between pottery and porcelain. Its characteristics include a dense, nearly vitrified structure, high strength, fine particles, and a conchoidal or stony fracture surface, but it lacks the translucency of porcelain. Existing Zisha clay, after firing, becomes hard and dense. Therefore, during tea brewing, there is little interaction between the inside and outside of the Zisha teapot, resulting in a higher internal temperature that keeps the tea leaves at a consistently high temperature, leading to a "steeped" state that negatively impacts the taste of the tea. Consequently, current Zisha teapots are generally not used for brewing green or yellow teas, but only for fermented teas such as black tea, Pu-erh tea, and red tea. Even when brewing these fermented teas, the high temperature affects the taste.

[0003] Teapots made from existing Zisha clay have more pores than porcelain, allowing the tea inside to interact with the outside environment. Therefore, Zisha containers have certain advantages over porcelain for brewing tea. However, from the perspective of user health, they remain at the level of the Ming Dynasty, and thus, there is currently a lack of Zisha clay on the market that can release trace elements. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a purple clay material rich in trace elements that has a high yield, is easy to shape after firing, and releases trace elements after soaking in water, along with its preparation method.

[0017] S6: Purification, using dry or wet adsorption methods to purify mineral materials;

[0018] S7: Aging, the purified minerals in step (6) are mixed with water to form a slurry, and placed in a closed environment at 15-20°C and 20%-30% relative humidity for 3-6 months.

[0019] S8: Clay preparation, which involves repeatedly pounding and pressing the clay mixture from S7 using equipment.

[0020] S9: Warehousing: Pack the kneaded purple clay materials into a warehouse for later use.

[0021] According to another aspect of the invention, a method for firing Zisha (purple clay) artifacts made from Zisha clay rich in trace elements is characterized by comprising the following steps:

[0022] S1: Preheating. Place the finished and naturally dried Zisha teapots into the kiln and heat them to 150℃-200℃ for 1-1.5 hours.

[0023] S2: Shaping and firing, the temperature inside the kiln is slowly reduced to 850℃-950℃, and the entire firing time is 8 hours;

[0024] S3: Cooling and polishing. After cooling, the Zisha (purple clay) ware is taken out and polished.

[0025] S4: Constant temperature firing. The polished Zisha teapot is put back into the kiln and the kiln temperature is slowly reduced to 1170℃-1190℃. The entire firing time is 6 hours.

[0026] S5: Cooling and unloading from the kiln. After firing and cooling, the Zisha teapots are removed from the kiln, inspected, and then stored.

[0027] In some implementations, the preheating temperature in S1 is 185°C.

[0028] In some embodiments, in S2, the firing temperature is 900°C, and it needs to be slowly raised to 900°C within 6 hours, and then maintained at 900°C for another 2 hours.

[0029] In some embodiments, in S4, the firing temperature is 1180°C, and it needs to be slowly raised to 1180°C within 3 hours, and then maintained at 1180°C for another 3 hours.

[0030] Compared with existing technologies, the advantages of this invention are: high yield, easy shaping after firing, and the release of trace elements after soaking in water. In this invention, by mixing purple clay with minerals rich in trace elements, the finished product itself is rich in trace elements after firing. When hot water is poured over it, the trace elements in the pot are released into the water, achieving a health-promoting effect. Detailed Implementation

[0031] The present invention will now be described in detail with reference to the various embodiments shown. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.

[0052] In actual use, it is recommended to use the proportions in Example 2, which have appropriate trace elements and make the clay easy to shape.

[0053] According to one aspect of the present invention, a method for producing purple clay material rich in trace elements includes the following steps:

[0054] S1: Selection of raw Zisha clay ore, which involves sorting one or more of the following raw Zisha clay, green clay, red clay, and Tuan clay ore one by one to remove obvious impurities from the ore.

[0055] S2: Weathering, the sorted ore is placed in open areas and allowed to weather naturally for more than 3 months;

[0056] S3: Mineral material selection: Selenium-silver ore, strontium ore, spodumene, and smithsonite are sorted one by one;

[0057] S4: Crushing, using a ring roller mill to crush the ore piece by piece, and then screening the crushed ore piece;

[0058] S5: Mixing: Mix mineral materials and raw purple clay ore in proportion;

[0059] S6: Purification, using dry or wet adsorption methods to purify mineral materials;

[0060] S7: Aging, the purified minerals in step (6) are mixed with water to form a slurry, and placed in a closed environment at 15-20°C and 20%-30% relative humidity for 3-6 months.

[0061] S8: Clay preparation, which involves repeatedly pounding and pressing the clay mixture from S7 using equipment.

[0062] S9: Warehousing: Pack the kneaded purple clay materials into a warehouse for later use.

[0063] According to another aspect of the invention, a method for firing Zisha (purple clay) artifacts made from Zisha clay rich in trace elements is characterized by comprising the following steps:

[0064] S1: Preheating. Place the finished and naturally dried Zisha teapots into the kiln and heat them to 150℃-200℃ for 1-1.5 hours.

[0065] S2: Shaping and firing, the temperature inside the kiln is slowly reduced to 850℃-950℃, and the entire firing time is 8 hours;

[0066] S3: Cooling and polishing. After cooling, the Zisha (purple clay) ware is taken out and polished.

[0067] S4: Constant temperature firing. The polished Zisha teapot is put back into the kiln and the kiln temperature is slowly reduced to 1170℃-1190℃. The entire firing time is 6 hours.

[0068] S5: Cooling and unloading from the kiln. After firing and cooling, the Zisha teapots are removed from the kiln, inspected, and then stored.

[0069] The preheating temperature in S1 is 185℃. Through experiments, it was found that when the preheating temperature is 185℃, the Zisha pottery needs to be kept in the kiln for preheating. Preheating keeps the temperature of the Zisha pottery at a relatively high level to prepare for the next heating.

[0070] In S2, the firing temperature is 900℃. It needs to be slowly raised to 900℃ over 6 hours and then maintained at 900℃ for another 2 hours. Raising the temperature to 900℃ over a relatively long period of time and slowly increasing the temperature prevents the Zisha ware from cracking due to excessive heating.

[0071] In S4, the firing temperature is 1180℃. It needs to be slowly raised to 1180℃ over 3 hours and then maintained at 1180℃ for another 3 hours. Experiments showed that if the firing temperature is too low, the internal and external interaction effect will not occur; if the temperature is too high, the internal and external interaction effect will be unstable. 1180℃ is the optimal temperature for achieving the best internal and external interaction effect after multiple trials.

[0072] The above descriptions are merely some embodiments of the present invention. It should be noted that those skilled in the art can make other modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
