The purpose of the bowl:
The general purpose is to hold food. Because the bowl is smaller than the pot bowl, it can be held by hand. The shape is wide and narrow, and it is unstable on the flat ground. Archaeologists speculate that the bowl used by ancient people may have been originally placed in a hole dug in the ground.
There is little difference between the bowls made of argillaceous pottery in Neolithic age and today, that is, the mouth is big and the bottom is small, the mouth is wide and the bottom is narrow, and there are bowl feet below. The height is generally half the diameter of the mouth edge, mostly round and rarely square. It's just that materials, technological level and decorative means are constantly changing.
