As will be seen from the record quoted here, every detail is marked down—the temperature, time of dyeing, price of material and where it was bought, in fact any little item that may be of help later. A full explanation of this sample page may be of service to some readers.
The record shows the process of dyeing in the making of the “Sorceress” panel, shown facing page [78]. The silk used for this panel was a very heavy Japanese crepe and the design was worked out in nine colours. That is to say, it was dipped eight times, the ninth being the original white of the silk. The only places where this original white shows is in a few little flowers in the branches of the trees, and these, on account of the many times the piece was dyed, have so much crackle in them that they do not appear as pure white.
The piece was first dyed a very light creamy yellow colour; this tone being composed of yellow, a speck of blue and a speck of orange. The mixture of these colours produces gold and a much diluted solution results in a straw yellow. The temperature for this bath was between 105° and 110° Fahr., and the time for dyeing about twenty minutes. After having been rinsed and dried, the parts of the design that were wanted the straw colour were covered in wax, the largest surface being the scarf of the Sorceress.
The panel was now ready for the second dipping. This was a light salmon pink, which over the straw-yellow gave the flesh colour for the face and body; this tone also appears in the light outline of the smoke and clouds. This salmon colour was made of orange and yellow mixed and was used very light. Temperature 110°; time, about 20 minutes.
The third bath was blue. This was used in the mountain in the background and in some of the leaves in the foreground on the piece. The blue was used pure, but not very strong. With the flesh colour, this gave a greyish blue. Temperature 110°. Time 15 minutes.
“SORCERESS” BY ARTHUR CRISP AND PIETER MIJER
The fourth colour was the same blue, only much stronger, and in this the trees in the mountain, the outlines of the mountain and the stems of the bigger leaves were dyed. The fabric was in this bath altogether about 40 minutes. The first half of this period the temperature of the dye was about 105° and was reduced to 90° for the last twenty minutes. This difference in the temperature was made in order to make the wax brittle and obtain a slight crackle to allow the penetration of the colour.
The crackle effect was not desired all over the design, so a second covering of wax was applied in some parts, after the material had been thoroughly dried. The face and body of the figure, in particular, were carefully gone over, as these parts had to remain as little as possible affected by the darker colours.
The panel was now dipped in an ammonia bath to extract the colour from the parts not covered by wax. This took from 15 to 20 minutes with a temperature of 100° Fahr. When the colour in the fabric was reduced to a light grey, the piece was transferred from the ammonia bath to a tub of clear water at the same temperature, and rinsed thoroughly for at least an hour, in order to remove every trace of the ammonia. After drying, the whole panel was carefully gone over to close all undesired cracks that had come during the colour extracting process; these were mainly in the figure and the scarf.
