In looking at the directions for Mike Ware's Argyrotype I see that he calls
for the use of 0.2 cc of Tween 20 wetting agent in the sensitizer. Does
anyone know exactly what purpose Tween fills in the sensitizer formula and
if it might be subsituted by some other agent, i.e. photoflo or propylene
glycol?
