    ok to speed up my work flow in the lab i dry my fiber base test strips in the microwave so i can see the dry down in a few seconds rather than have to wait ages. well today i decided something irregular I was drying down some Ilford Silk fiber base paper and i meant to type 30 seconds but i typed 3 minutes....the phone rang....test strip was microwaving and i didn't stop it.

    when i got to the microwave the test strip was buckled and when i removed it i made a discovery the coating had separated form the paper.I now had a loose image which i could flex and crumple.

    So I decided to check out if this was a one off or repeatable so i did it again, Same result. So I printed a whole 8x10" sheet and microwaved it for 8 minutes. same result. the whole 8x10 coating separated.

    Im not sure if other Fiber coatings do this, or weather resin also does it. but for now that something i thought i would post as i found it interesting and this may creative application. also i noticed the coating is now translucent.

    Throw one on your scanner, I think we all would love to see such a crumpled one.

    8-minutes!!? I burned a hole in my RC print after 3-minutes, at 1-minute the gloss finish wrinkles and the paper buckles. I think "this myth is busted." RCs blow drys in about 2 minutes so I don't bother with the microwave anymore.

    Why? To see what would happen. I heard that the waver would make your whites "pop." It was more like poof, up in smoke.

    Sounds like you have the answer to the polaroid image transfer in FB. Have you tried rewetting and floating it onto a sheet of watercolor paper?

    When I have overcooked (Varycon, Polywarmtone, Adox VarioClassic, Ilford MGIV) I have done nothing more than burn a hole in the paper. Perhaps it is paper brand specific, or perhaps it is your particular microwave. One could, I suppose , try to float an emulsion of using a more even source of heat.....

    the one problem i have noticed is the plastic bumbs of the silk surface melt and become a smoother gloss.

    What plastic??
    Or do you mean the gelatine structure?


    Are there residues of the baryta adhering to the gelatine layer?

    I bet it's the microwave oven. They vary quite a lot in the evenness of their microwave distribution. With some, if you put in an even layer of something (say, pre-cut cheese slices), you'll find some are stone cold while others are bubbling away. With other microwaves, the distribution is much more even.

    Using a rotating platform sometimes helps. If you've got an oven without one, I know that they exist (or did exist) as add-on things. I've got one in mine that you rotate and then it slowly rotates back, like a wind-up toy.

    This sounds like the emulsion lift you can do with polaroids and warm water. It would be super-cool if you could do the same thing, emulsion on watercolor-paper that's a bit crumbled looks great!
