Hej alla,
här kommer en länk till en sida om färgning, mest olika typer av skinn, men även silke m.m.
"The Segreti per Colori, or "Secrets of Colors" was a mid-15th century manuscript in latinized Italian. It is a small volume in duodecimo, on cotton paper, and is preserved in the Library of the R. R. Canonici Regolari in the convent of S. Salvatore in bologna. It is numbered 165.
The latin text of the manuscript and its English translation forms a major part of Mary Merrifield's "Original Treatises on the Arts of Painting", published in 1849. The section of this which is reproduced below is chapter 8, on dyeing fabric, coloring leather and making chamois.
I have also included recipes for the pigments indigo, verzino and oricello, all of which are mentioned in the dye recipes."
