I was reading through a thread on Photo.net from 2004 dealing with accelerants for Gainer's developers. At the time, I had little interest in borax, but used carbonate or TEA. It turns out that the high solubility of borax in glycol is accompanied by formation of boronate esters that will be completely useless as bases. This is most likely to happen when heat is used to hasten solution. It explains why I thought my pH meter had gone bonkers. A working solution did a pretty good job of stand development at 45 minutes, 70 F.
