I pour my RA4 chemicals back into glass storage bottles. I find if the

make up 2x the amount of blix that I do developer. Some times there is black
crud in the bottom of the bottle. But that's the worst thing I've had to deal
with.
I also do a prewash with the RA4 paper which stops the paper from sucking up
all the developer. I've told this is bad since it dilutes the developer. But
so far so good. I guess the stop helps protect the blix from the developer
pH.

I buy the Kodak 1 gallon RA4 kits and mix one quart at a time. I process the
paper in a CPP-2, with a pre-soak and a stop bath. I reuse the chemistry -
70ml per 8x10 print. I drain each step into a beaker, then pour it back into
the original brown glass bottle when I'm done. I've had the partially used
chemicals last up to 3 months this way, and can get up to 50 8x10's from a
quart with no degradation of colors.
