Service life: uncoated pot has long service life, can resist high temperature and is not easy to be damaged. However, the coated pot is easy to age and burn at high temperature because it needs external coating, and its service life is short.
Safety: the uncoated pot will not release any harmful substances, which fully meets the green health standards. In contrast, coated pots may have chemical risks. Some coatings may contain unhealthy compounds, such as PFOA and PTFE, which may release harmful gases at high temperature and have adverse effects on human health. So uncoated casserole is good.
