    I use an old FB print dryer. Takes about 8~10 mins to dry a test strip/print. This method has never let me down, though obviously you need an FB dryer to start with! Might try the microwave method, but I'd like to be sure I wouldn't knacker it up in the process (the microwave I mean).

    Thanks everyone....I was going to dry the test strips on an aga, which dries most things in next to no time. Intrigued by the 3 minute developing preocedure & might give it a go. I'm getting ahead of myself as I don't plan to open the box of paper until my burning / dodging on rc has improved (see different thread). I'm burning paper & making progress...

    I've used a microwave for 20-years with no problems. I still find that the viewing light and angle needs to be consistent - the Sexton method sounds like a good idea.

    How long do you develop your prints for? I was fortunate enough to take George Tice's b&w printing workshop in Maine about 10 years ago. I learned that if you develop your prints for 3 minutes you significantly reduce drydown, almost to the point of irrelevancy. I still print that way to this day. Dean
    I find this not to be true at least for the Ilford MGIV fiber paper I use. I develop for between 2 1/2 to 3 minutes, actually closer to the 3 minutes and find that the paper dries down somewhere around 10-12% maybe higher. I use the microwave to test dry my prints and find it works pretty well. If the print seems good after microwaving I re-wet the print and put it back into the print washer with no ill effects. (At least so far after a few years) I'm thinking of getting a microwave that can take 11X14 prints as my current one will will only accomodate 8X10. When I think I've nailed an 11X14 I rip it in half before putting it in the oven

    How long do you have to microwave a 10 x 8 MGIV piece of paper ?

    Until it's dry?

    I always understood drydown to be due to the swell of the wet emulsion causing silver particles to seperate and appear less dense - as it dries, the emulsion shrinks and the particles draw closer, and hence the tones darken. How can increasing development times alter a physical characteristic of the emulsion/paper?

    Microwaving a print is like microwaving food - time depends on the microwave oven's power. In mine (which I think is 1000 watts) I cook and 8x10 Azo print for 45 seconds. It's not completely dry when I take it out, but it air drys completely in another minute or so. YMMV.

    I have notes at home but if my recollection is correct I cook it for about 2 min 45 sec on #7 power. The way my and I think most microwaves works is #7 means it is on for 70% of the time at full power. When I cooked it for a shorter time on full power parts of the paper would burn. So at 70% it has a chance to cool off before the power goes on again. YMMV.
