Chapter CV

Have a holy horror of useless impasto, which gets sticky and dull, turns blue and heavy. When you have painted a bit of which you are doubtful, wait till the moment when it will be possible for you to take it out. Judge it; and if it is condemned, remove it firmly with your palette-knife, without rubbing by rags which spoil the limpidity of the pigment. You will have left a delicate foundation, to which you can return and finish with little labour, because your canvas will have received a first coating. Loading and massing the pigment is an abomination. In twenty-four hours gold turns to lead.
