(iii) Dropping When rain falls, the rain water will be treated in the following three ways. A part of it soaks into the soil and evaporates, and another part of the water flows on the ground and forms a river. Similar phenomena are observed in the case of paints and paper. When shapes are drawn using paints with less water or on hygroscopic paper, the paints are absorbed by the paper in a short time, and are dried by evaporation. The paints flows like a river if the paper is tilted when the paints contain much water and less hygroscopic paper was used. Poster colors and color inks were dropped on a piece of paper for watercolor painting as shown in Figure 592. It is interesting that the dropping distance varies according to the difference in viscosity of the colors. Figure 593 represents an illustration drawn with great effort using a thick piece of mat paper, and the paper was tilted with various angles to flow colors. The lines have different tastes which cannot be expressed by brush painting. The two drawing techniques "dropping" and "blurring"
were both used since wet paper and much ink were used as shown in Figure
594.
