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

2. Due to the problems of manufacturing technology and raw materials, the traditional casserole is not resistant to temperature difference and explosive, so it can't 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.
