Is the iron pot covered with wood or glass?

Cover the glass. The glass cover of the iron pot is better, because the glass cover is transparent, and the inside of the pot can be seen from the outside. The wooden cover needs to be picked up to see the inside, and the glass cover is not easy to mold when it meets water, and the wooden cover is easy to mold when it meets water, which is not conducive to daily use, so the glass cover is better.
