Factory worker uses traditional jigger machine to make each bowl in seconds.
He turns a large pile of super soft clay into jiggered bowls, one after another. Notice how he deliberately puts in too much clay but catches the excess efficiently for the next piece. Also notice the inner, likely 3d printed liner, on the plaster wheel head, enabling them to precisely fit it to the molds.

Factory worker double-layer glazes outside of vase
She does the second dip immediately after the first one. A small board is attached to the rim to prevent the outer darker glaze from going inside, she knocks it off as she quickly carries the flared-footed vase to the second drum of white glaze.
