Due to the problems of production process and raw materials, traditional casseroles are not resistant to temperature changes, easy to crack, and cannot be dried. In view of this problem of traditional casserole, in the past ten years, after R&D and improvement, spodumene was added to the raw materials to create a high temperature resistant casserole, so that the casserole can withstand several hundred degrees of dry burning without cracking while maintaining its original advantages, greatly improving the practicability of the casserole.
