Just like dance, pottery has its daily practice. You warm up with some standard shapes, cups perhaps, and then move on to more complex forms. The adagio happens when all your haptic muscles are warmed and you can effortlessly flow through forms. Beyond touch, your mind and expression are all synced up.
For me Picasso was always the ultimate vision of an artist who luxuriated in an endless flow of creativity, basically he was always warmed up. He is my romantic vision of an artist at peak performance perfecting and re ordering imagery.
Picasso jumped back and forth between 2D & 3D drawing. The energy of his 2D work is enhanced in clay because he could literally dig into it. Weight of line takes on a new meaning when clay is involved. Edges, corners, turns, and diminishing points become physical form that control space.
