Silt and salt “There was a period—or at least you hoped there was—with every painting or project when the life of that painting became more real to you than your everyday life, when you sat wherever you were and thought only of returning to the studio, when you were barely conscious that you had tapped out a hill of salt onto the dinner table and in it were drawing your plots and patterns and plans, the white grains moving under your fingertip like silt.” Q1:『the white grains moving under your fingertip like silt』how tougher stand this sentence? Q2: why he would tapped out a hill of salt onto the dinner table? My preception is that when you only think about the art, the project, the salt would pour into the cook pot while cooking rather the on dinner table. I'm a Chinese, does western cooking pour salt while on dinner table OR I misunderstood ?Q1: how to understand 『the white grains moving under your fingertip like salt 』
