I waited an hour than added soda ash. I also added more thread at this time, some bags got more rayon thread, and each got some mystery white yarn that appeared to be cotton. I let it sit for a few hours then rinsed them out in the sink with synthrapol and water a bunch of times. I need to start tying my yarns and threads prior to dyeing so they don't end up a tangled mess.
Here are my end results. The center shows the white rayon that I started with. I believe my colors are (starting at the top, then clockwise): Pagoda Red, Hot Pink, Golden Yellow, Bright green, Don't remember, Lapis (I think?), and Deep Purple (I think?).
