No, I didn't add sizing. I was hoping I'd be able to avoid the sizing
hassles. I'll run a test the next time I size a batch of paper. Thanks!

... and did you size between cyano and VDB?

Well, I mixed up a batch of Van Dyke Brown emulsion and spread it over some
pretty dense cyanotypes. The results, using the straight solution and the
1:1 water mix suggested by garimo were both disasters. I could probably
handle some bleaching, even a lot of bleaching if it were consistent, but
what I got was a very mottled and streaky result that looked horrendous.

Hi garimo,

The kallitype formula I used was Silver Nitrate and Ferric Oxalate. I'll
try using Van Dyke brown when I get a chance to mix a batch.

Thanks!

 Don't know if by kallitype you mean the same formula as Van dyke
Brown... but I dilute the VDB solution in half(1:1) with water. I tried
other dilutions but I liked the 1:1 best. Different exposure times of
the VDB have different effects in the final print.
good luck!
