You're right, of course. You have to heat the glycol as you do the TEA, thus making the stock just as time-consuming to mix, and that's the reason I only have used the glycol to experiment with single solution developers that contain all ingredients--developing agents and activators.

When I'm developing, it's a liter of water, a half tsp. Vitamin C, a whole tsp of metaborate or carbonate, and 4 ml Phenidone stock. Takes 2-3 minutes, doesn't demand heating ingredients, measuring dilutions, etc. I'm naturally lazy, and since I get great printable negs with long scale and fine grain, why bother with something more, well, bothersome? I can mix AND develop in the same amount of time I would have just to develop using TEA (unless I use a 1:25 or 1:30 dilution instead of the recommended 1:50, which shortens the time from 9-10 minutes to my preferred 7 or so). Believe me, I have nothing against TEA. It's a fine developing activator. And I've got nearly a full quart that's sitting on my shelf unused after my experiments with it. Since my first attempts produced an oderiferous result, and others report no such effect, I conclude that I overheated it (though it worked well), and may try it again sometime while monitoring the temperature more closely. Or maybe not. I really couldn't see any real gain in the negs I got from it over what I've been using for several years now.
