Unveiling the Data Hierarchy: Capitalizing on the Hot Trend of Data
Rongxian County, Sichuan Province, is the hometown of earthenware. It has a thousand years of pottery making history, unique clay resources and magical manufacturing technology. Changshan Town has superior geographical and regional advantages. It is located in the northwest of Rongxian County, 29 kilometers away from the county seat, and covers an area of 81.2 square kilometers. It is the second level central town of the county and the third level central town of the city. The proven domestic high-quality clay reserves are more than 400 million tons. Relying on such superior natural conditions, Ruihong Ceramics emerged as the times require and stood on the land of Changshan. It is well known that only good soil can produce good crops. The clay in Rongxian County has three unique advantages that other clay in China do not have:
（1） Rongxian clay has a reasonable element content ratio: 65% silicon, 2.5% iron, 21% aluminum, 0.4% calcium; It also contains potassium, sodium, titanium and other trace elements needed by the human body. The products fired with Rongxian clay have higher furnace temperature requirements than ordinary clay, smaller product deformation, higher density, and the characteristics of hardness, hardness and toughness; It has the functions of natural acid resistance, alkali resistance and anti-corrosion. The cellar liquor has no leakage for more than 20 years, which reduces the cost of turning over the common wine jars after three years, saving the wine enterprises expensive storage costs;
（2） Rongxian clay has a rare natural glaze clay in Southeast Asia - blue glaze. It is identified by the relevant national inspection department that there are no harmful substances and elements to human body, and it belongs to the natural environment-friendly glaze mud;

For this reason, Rongxian earthenware has the same congenital conditions as the famous purple clay pottery in Yixing, Jiangsu and Zibo, Shandong.
The firing temperature of the ceramic wine jar is 1380 ℃, and it is fired through multiple processes. After firing at the temperature, the precious metal elements in the soil can be burned, making the soil more pure, and the safety of the ceramic wine jar is also improved.
2. No leakage
After high-temperature firing, the density of ceramic wine jars becomes larger, and after being glazed on both sides, it ensures that wine will not leak through the jar wall, and it also avoids the possibility that wine will volatilize from the jar.
From the selection of soil, the firing of wine jars to the final products, each process is of high standards and strict requirements, and the wine jars made are more durable.
With the continuous improvement of people's pursuit of individuality, ceramic wine jars have various decorative techniques and outstanding personality. The ornamental value, decorative effect and artistic taste also keep pace with the times, making them more ornamental and collectible.
5. Aging effect
The trace elements contained in ceramic wine jars are conducive to the aging of liquor and health.
