Renee wondered what kind of dye I was using. For silk I use Sabraset/Lanaset dyes from ProChem. I have dyed silk with fiber reactive dyes. They yield nice results but not the brilliance that the Sabraset/Lanaset dyes do.
Once the initial 20 minutes of continually dipping the fiber in and out of the dye pot (10 minutes with the chemical additives, then 10 minutes with the dye solution poured in), is done, there is very little stirring or moving that needs to be done. Some, yes. But most of the color by that point has been absorbed. But not all. The darkened parts were clearly scorched areas. I laughed to myself when I realized that, for I thought about when I have done the very same thing to food.
