Steps:
-Drop 2 grams of palladium metal in Aqua regia.
-Heat until reaction is complete adding more AR if necessary.
-Heat until all acids have evaporated and the the solid product is all that remains.
-Add few mls of conc HCl to dissolve everything.
-Heat to evaporate all the HCl
-Repeat two steps above 2-3 more times.
-Dry the product that should be pure PdCl2
I want to know if the last 4 steps are necessary. Wikipedia states that palladium nitrate decomposes before reaching 100 degrees.

Dont see anything wrong with your procedure.
Whats the deal with PdCl2 anyways. I see it sold on ebay very frequently

Well, there ARE a lot of kids interested in stylishly retro photographic chemistry, using various chemicals such as this. I have seen some VERY nice
prints done with such, kind of like the resurgence of vinyl records, there's a movement towards old school film cameras/optical printing processes.

And possibly a few contemplating a Wacker oxidation?

But surely not most. Art photography is a siren, her song irresistibly luring many of our clean living young folk to the techniques of Ansel Adams
and his contemporaries...

I have this never ending drive to photograph nature in Ir or uV, or Ir-uV combined. Seeing nature as insects, birds and other animals do. Especially
trees. So incredibly cool its freaky. Alien landscape freaky. I love it. The better you filter out all of the visible spectrum the more fantastic
nature appears.
