Hello, it should be possible to use ceramic materials for small household fryers.
However, I personally recommend using a stainless steel fryer. Of course, the quality of stainless steel is also very important. For example, the density of 18-10 high-quality stainless steel is greater than that of iron, so it will not absorb overnight oil and will not produce oily smoke as big as an iron pot during use, which is relatively healthier and safer.
