I'm going to resurrect this thread in order to keep the search for PC dye recipes. I have a rather ambitious project of dyeing linen (Bleached & Unbleached) and wool in period dye baths. Then age 3 swatches in the sun for different times. (Probably 1 month, 6 months and 1 year.) Put all this crap into a "swatch book" of sorts to have a reference for colors.
Point me in the right direction. I'll start reading.
I own and have read this book. The Craft of Natural Dyeing by Jenny Dean I'm just not sure how period the dye recipes are. I'm sure they are pretty close though, considering the whole book is devoted to using natural elements in the dye baths.
Also any word on dye "fixatives"? I've heard salt being used but in my experience (using Rit dyes) I have not seen it work effectively. (I'm aware of mordants and washes that can be used.)
Lastly if anyone has any suggestions on what else I might need to do or test, please speak up. I'm planning on starting this in the spring. I'll keep those posted in a new thread when I start. Thanks all!
