I've been using Barry Thornton's developers for a long
time. They are pyrocatechol based developers. Before
Barry, I used a highly compensating Windisch pyrocatechol
formula with great success.
This sounds really great. But, isn't it pretty toxic too?
Don't you have to be more careful than with ordinary
developers?

I've never been sure if the toxicity of developers like
Pyrogallol and its derivatives and para phenelyne diamene
refer to skin sensitivity or to actual toxicity (i.e., they
kill you dead). I rather think the former. Metol is also a
common sensitizer causing some people to develop very
serious rashes. There are not many chemicals used in
conventional photography which acutely toxic but its still a
good idea to keep them off your skin and out of your mouth.
