LXIX. To marble and Jasper Paper. 1. Grind all the colors you want to employ (such as lake, massicot, indigo, yellow and red ochre, etc. etc.) with bullock's gall; grind each separately, and keep them so. Then have a large and side pan filled with lukewarm gum water. Stir well that water with a stick. While it is in motion, and your colors being ready under your hand, with a large brush, take of each separately, as much as the tip of the brush will carry, and touch only the surface of the water with it. The colors will immediately expand. Each color requires a particular brush to itself. Therefore, with another brush, take of another color, and do the same; and, with another of another, and so on, till you have put on your water all those you have destined for the purpose. 2. When the water ceases to turn, you will plainly
perceive all the variety occasioned by the different colors. Then, taking
your sheet of paper, lay it flat on the water, leave it there for about two or
three minutes, and, without taking it out, give it one turn round on the water,
then pull it by one of the edges to the side of the pan, wash it, dry it, and
burnish it afterwards.
