Perry: Thanks for your reply.
However: I always use non hardening fix! (I use Tetenal Vario fix, which is non hardening)
your second comment: The warm colour is normal when using liquid emulsion - it goes away when re-fixing and rinsing.
The (frustrating) thing is, that I used the exact same bleach yesterday, and ALL the image went away - today not...
It is mostly that I don't understand....
for developing I use Tetenal Eukobrom or Tetenal Centrabrom.
Fix: Tetenal vaario fix (non hardening)
Bleach: Copper sulphate - potassium bromide and potassium dichromate....
