I'm in Fall River at PRO Chemical for a 1-week workshop with Carol Soderlund called "Dyeing to Discharge." It's hard to believe, but this will be my 5th class with Carol. I'm going to have to ask for a degree soon.
Discharge is a dyer's term for removing dye from cloth. Think of it as the dyer's equivalent of an eraser. It's among the most basic techniques, but not something that I've ever really felt that I could control to the level that I want. That's what the next 5 days will be about: really learning to control the process with different types of chemistry--reductive (thiox) and oxidative (hypochlorite)--to get predictable, reproducible results.
If you're not a dyer, a chemist, or a nerd (or a little bit of each) this might sound tedious, but I'm really looking forward to it.
Stay tuned this week to hear how about what I'm learning.
