Oh, that's just gorgeous.

@MurrayMinchin: are you using a kit or making Silver Sulphamate yourself as outlined in Mike Ware's writeup?

Oh, that's just gorgeous. I mean, the digital image goes quite a way in suggesting what the actual print must look & feel like, and that certainly must be gorgeous!

Thanks a bunch. Zeroing in on which Gampi right now. Platinum should be here in a while, then it'll be deciding which to use (platinum or palladium) or in what combination.

Hi Ragu, I'm using Mike Ware's articles so using Silver Oxide as an ingredient which I guess ends up being Silver Sulphamate after mixing the sensitizer.

Your print along with the video @loccdor posted here have got me musing about finally giving these gorgeous papers a go. I'm leaning initially towards salt prints at least to come to grips with the unique nature of the material (read: figuring out how to handle the wet sheets...) Ideally I'd end up with some other process, preferably pigment-based, but I haven't figured out a good direction yet.

I've seen other people coat light weight Kozo and Gampi when it's dry, but I've been using another technique.

1) Place Gampi on a sheet of glass.
2) With a brush, wet out Gampi with distilled water
3) Tease a thin sheet of plastic (strip of OHP film or Rubylith) under one short edge
4) Lift wrinkled Gampi off glass, then drape slowly back onto glass from opposite edge, so it lays flat
5) With wet brush, stroke out gently from centre outwards until it has an even sheen and no bubbles
6) use a paper towel to blot off sheen...but no more!
7) Coat with normal amount of sensitizer
8) Takes between 15 to 20 minutes to dry in the dark under a fan
9) Using a razor, gently release edges and lift off glass.

This ensures the even absorption of sensitizer.

You can use pieces of OHP film or Rubylith to lift the paper out of solutions by gently guiding it under a short edge, holding the Gampi in place with a thumb, then slooowly lift it out of solution while holding the OHP at a slight angle to create enough friction so it doesn't fall off.

To dry...drape on glass, blot with paper, place under fan, put a small weight on a corner so it doesn't blow away if it comes off the glass. Takes about 30 minutes.

As of this date, that's how I'm doing things...subject to change at any time!

Thanks, very useful tips for sure!

Thanks, very useful tips for sure!

Also, beware that some Washi has a rough and a smooth side. Typically, the smooth side is for the artwork and the rough side is for glueing to heavier support paper using wheat starch glue. If you coat the rough side with sensitizer, it can fuzz up fast even with light brush strokes.

Happy to be on a tangent of inspiration. I think that is the best possible outcome and purpose from a forum like this. Looking forward to your work which I know will be excellent.

Ok, I would have to make some Silver Oxide first as I have only Silver Nitrate. If you keep posting as excellent a result as the previous one, I'll be amply motivated to take that step soon.

Ware gives several ways to get from Silver Nitrate to Silver Sulphamate, but I suspect you are pretty comfortable in a chemistry lab so shouldn't be a problem.

There are struggles early on adjustment curve wise (some people call them Angrytypes) but processing isn't one of them. Two weak citric acid soaks with tap water (I have jugs sitting around for at least a day to dechlorinate) then into a toning solution about 1/2 as strong as you would for a Kallitype (this may be because I'm using Gampi and not heavier European 100% cotton papers) then two minutes in a 2% (Ware also mentions 2.5%) Sodium Thiosulphate fixer. He makes no mention of a second fix or hypo clearing agent. I'm using one year old sensitizer. Very quick and uncomplicated processing

I'll dive into the research/testing regarding the fix/washing end of things before doing final prints.

Hint: being a printing out process you get a pretty good idea of what an image will look like right out of the exposure unit, but they go wandering all over the map as they move through the solutions and dry down hugely in the low values....make no snap judgments until fully dry!
