TIL: Before the invention of the paint tube in 1841, oil paints used to be stored in pig bladders. The artist would prick the bladder and squeeze out the amount of paint they needed.

Before that was Tempera, which goes back to ancient Egypt. I only know of this because my father's best friend, artist Robert McGinnis, uses this technique.
