The solubility of sodium carbonate (anhydrous) is about 150 g/l @ 20 C. The
solubility of the monohydrate would only be slightly higher. Since the formula
calls for 30 g/l it would therefore be impossible to prepare a 8X concentrate of
this developer.

Subject: [pure-silver] DS-14 Concentrate ?'s
I mixed up a batch of DS-14 and had trouble getting the sodium carbonate
intosuspension when mixing the 8X version. I finally adjusted the water to end
up with a concentrate to use at 1:4. Everything went fine then. any tricks to
this? Temperature issues?
I like the results I've gotten but have only used it on some quick RC shots in
one darkroom session. I'm also testing my posting to pure-silver and willuse
this message to see if I've got the procedure down.
