The bowl opening is inclined outward, with sharp lips, straight or slightly curved abdominal wall, shallow abdomen and adduction under the abdomen.

Key points of building kiln and making lights
Preparation of embryo mud: mix the main raw materials such as yellow mud, clay and red soil according to the requirements of lamp making. Soak in a pool, stir to make slurry, filter with a 100-200 mesh screen, soak again, stir and filter, repeat for 4-5 times, make paste mud, and seal it in the shade without changing its taste. Make germ mud uniform, fine and free from visible impurities.
Manual blank drawing and semi-manual blank drawing are adopted. After the blank is dried and glazed to a certain extent, the blank is trimmed. After trimming, the blank is dried, baked and glazed, or directly glazed after trimming. Semi-exposed tire is glazed with inner swing and outer bubble, and the part near the outside of the foot is not glazed. The traditional wood kiln, electric kiln and gas kiln are used for firing.
