And its plasticity is strong, which can be shaped into various shapes according to people's wishes, such as mud in the hands of skilled craftsmen, which can change endlessly to meet different needs. These various physical properties complement each other to achieve the extraordinary quality of this product.

There are various ways to make this product, each with its own wonders. The following are a few common methods.
One is the method of inheritance of ancient methods. According to ancient methods, the selection of materials is quite exquisite. It is necessary to choose high-quality materials and process them through multiple fine processes. If you pick rare materials in the mountains, you must go through various steps such as washing, drying, grinding, etc., and each step has strict rules. Drying needs to be selected on a sunny day, the duration is also fixed, and grinding needs to be ground to a very fine level before it can be used for backup. Then, according to a specific ratio, all kinds of materials are mixed, and then simmered slowly. The control of the heat during this period depends on the experience of the craftsman. If the fire is large, the material will be coke, and if the fire is small, the work will not be completed. This process needs to be kept in mind and carefully guarded until the desired product is obtained.
The second is the method of improvement. On the basis of ancient methods, combined with today's technology. When selecting materials, advanced testing instruments are used to ensure the purity and quality of the materials. In the mixing process, precise measurement tools are used to make the ratio more accurate. Heating is not just about relying on fire, but using controllable heating equipment can precisely adjust temperature and time. In this way, not only the production efficiency is improved, but the stability and uniformity of the product are better.
The third is the method of innovation. Incorporate novel concepts and technologies to explore new material combinations. With a unique chemical reaction principle, a unique synthesis path is developed. This path may involve cutting-edge chemical processes, or the introduction of bioengineering methods, breaking through the limitations of tradition and giving products new characteristics and advantages. However, its research and development process often requires a lot of energy and resources, and it has undergone countless tests and adjustments to be successful.
All these combined methods have their own strengths and weaknesses, either emphasizing the charm of tradition, or seeking modern efficiency, or pursuing innovative breakthroughs, all of which are unremitting exploration for the achievement of high-quality products.

When storing and transporting this item, you need to pay attention to many matters. First and foremost, when storing, you must find a dry and ventilated place. If it is in a humid place, the item is susceptible to moisture erosion, causing damage to its material, or even mildew, which damages the quality and function of the item. Poor ventilation will also cause turbid gas to accumulate and affect the preservation state of the item.
Second, temperature control is also crucial. Different items have different temperature tolerances, and it is necessary to maintain a suitable temperature according to their characteristics. Overheating may cause the item to soften, deform, and even cause chemical changes; overcooling may make its texture brittle, reduce toughness, and be prone to damage when used in the future.
During transportation, stable packaging is indispensable. It is necessary to wrap items with appropriate materials to protect them from collisions and vibrations. Packaging materials should have cushioning properties and can effectively absorb external shocks. If the packaging is not solid, items are easily hit by foreign objects on a bumpy road, causing surface scratches and internal structural damage.
Furthermore, when handling, be sure to handle them with care. Do not throw or drag items wantonly to prevent damage due to severe external forces. Staff should be familiar with the characteristics of items and handling points, and operate with caution.
In addition, for some special items, specific storage and transportation specifications need to be followed. If it is volatile, good ventilation and sealing measures should be taken in the storage area to prevent the leakage of volatile substances; if it is sensitive to light, it should avoid direct sunlight during transportation and storage, and can be packaged with shading or stored in a dark place. Only by paying careful attention to the above things can we ensure that the goods are intact during storage and transportation, maintaining their original quality and value.
