Good morning!
I use Tween 20 for cyanotype sometimes, and on my little bottle it says a
10% solution. I see it offered for sale at 100%. What percentage do you
all commonly use and for what process? Is it different for each process? I
always assumed it was a 20% solution (silly me, thinking Tween 20 meant 20%)
until I read the fine print on the bottle and then went to buy some more.
