Specific introduction of casserole:

Casserole is a kind of cooker. Traditional casserole is a ceramic product made of raw materials that are not easy to transfer heat, such as seasonable, feldspar and clay. Fired at high temperature, it has the characteristics of air permeability, adsorption, uniform heat transfer and slow heat dissipation. The recipes that depend on casserole include casserole chicken, casserole tofu, casserole fish head and so on.

Due to the problems of manufacturing technology and raw materials, the traditional casserole is not resistant to the change of temperature difference, easy to burst and cannot be dry-burned. Aiming at this problem of traditional casserole, in recent ten years, after research and improvement, spodumene was added into raw materials to make a high-temperature resistant casserole, which can withstand hundreds of degrees of high temperature without cracking while maintaining its original advantages, greatly improving the practicality of casserole.

Historical background:

The traditional casserole is a kind of pottery. The invention of Tao is an epoch-making symbol in the development history of human society and the greatest invention of human development. Legend has it that Emperor Yao invented the casserole, which has a history of thousands of years. Archaeological findings show that as early as the Neolithic Age, people began to use sand-filled pottery (similar to casserole).

Sand-mixed pottery is a common kind of pottery in Neolithic Age, mainly red pottery and gray pottery. After the improvement of past dynasties, sand pottery has evolved into the casserole we use now. Casserole can transfer the external heat energy to the internal raw materials in a balanced and lasting way. A relatively balanced ambient temperature is conducive to the mutual penetration of water molecules and food. The longer this mutual penetration lasts, the more delicious ingredients will overflow.

The fresher and more mellow the soup, the crisper and worse the texture of the stew. Iron wire casserole is a traditional handicraft. This casserole is characterized by its use of wire and binding workers. Many casseroles with hoops on the market are made of very thin iron wire, which is not close to the pot body at all. In this case, not only the iron wire is easy to burn.

Methods and loose slung can't protect the casserole at all. The earthenware casserole with hoop is made of strong thick iron wire, which is tied by an old master with many years of hoop experience. The unique hoop pot technology makes the iron wire close to the pot body. Therefore, compared with ordinary casseroles, the durability of well-tied casseroles has been significantly improved.
