At first, pottery vessels were produced just for practical use, as their producers had no time and energy to spare to "decorate" their products for some sort of aesthetic taste. Among the earliest pottery ware unearthed so far, only a few containers have crude lines painted red round their necks. As life improved along with development of primitive agriculture, people came to have time to spare on undertakings other than for a mere subsistence -- crop farming, hunting, animal raising, etc.
