1. Avoid empty burning and sudden changes in heat and cold. Before use, put oil or water in the pot first, and then heat it. According to the specified thermal stability standard, the cooker can adapt to the temperature difference from 320 ° C to 20 ° C. beyond this range, it is easy to burst and break porcelain.
2. When steaming with a porcelain bowl, use bamboo mats, otherwise the water in the bottom ring of the bowl will dry out first, causing porcelain peeling. If you steam with a flat bottom enamel bowl, there will be no porcelain peeling.
3. When cooking hoof bladder and white fungus in a pot, it is necessary to prevent the bottom of the pot from scorching. If there is coke, soak it in water for several hours, and remove the coke with bamboo chips. Do not use hard sharp tools to remove the coke and damage the porcelain surface.
4. If dirt appears in the pot after long use, you can scrub it with alkaline water and soap powder, or add water and boil it with a trace of acetic acid, and the porcelain surface will be clean without damaging it.
