Response to The Problem with Xtol - Some After Thoughts

from Conrad Hoffman (choffman@rpa.net)
I'm convinced there's something different about peoples water, air, technique, or *something*, that would explain this. I just mixed up a fresh batch of 1L XTOL last night and will do some film today. I hope I'm not jinxing myself, but I've never had an XTOL failure since the stuff was introduced. One note. I'm fussy about having every speck of part A disolved before adding part B. This takes time and effort. Last night I put the mixing jug on a magnetic stirrer. It took more than a half an hour of mixing (85 deg to start) before every tiny particle of part A was dissolved. When I was doing it by hand, I'd mash the particles with the stirring rod and keep mixing. We're not talking caked powder here, just the normal process of getting the stuff dissolved. 99% of it goes quickly, but the last few grains are quite stubborn. The stuff normally works just super for me and I'll report back later with how this batch went.
