RE: success!

I agree with Tony. I don't use tween for my prints. I mix it into the
student's emulsion as they're a ll using cheapo foam brushes and need
all the help they can get to perform smooth coatings.

Hi Christine

Mike Ware's instructions for making up the Argyrotype sensitiser call

for the addition of 0.2 cc of (Tween 20) to 100 cc of the sensitiser.

If you are adding 1 cc to the sensitiser for one print then I'm
surprised that the emulsion hasn't soaked right through the paper and

into the room below!!

The theory behind adding Tween is described in the following link bit
I
would heed the final sentence ...

Personally, I would forget the Tween as it is often more trouble than

it's worth.

Cheers ... Tony McLean
