Mix Palladium Chloride for Photographic Printing - Formula and Links in Description

Excellent presentation !

[@arnaldostudio]

Dear Bill! Glad to see you’re well. What a beautiful video! Brought back a lot of lovely memories of Photostock. Hope to make back to another one soon! :)

[@BillSchwab]

Great to hear from you, Arnaldo! Thank you for reaching out!! I do hope you are well.

[@travis0271]

Great to see you making videos, Bill! I've always admired your work.

[@BillSchwab]

Thank you, Travis!

Bill - suggestion - get yourself a tiny plastic funnel. Drop the powder off the paper into the funnel directly into the bottle, then pour in the beaker of Salt water. No waste powder left in the funnel (its washed in) and nothing at all in the beaker. Shake and put into the hot water bath for final dissolving of the powder... Works fine. Best regards

[@donnelson2250]

And very nice job on the video! Good to see you promoting the craft.

[@BillSchwab]

Hi Don, thank you! My experience with plastic funnels hasn’t been good. I actually have a small glass one that I use. We all have our ways of doing it and in every way there is some residual powder left. More of a stain than anything. I appreciate the input. I’m sure it will help people further find their way.

[@greg7mdp2]

Nice video, Bill. Just an idea, in order to waste a minimum of the precious powder, I would weigh the palladium chloride in a second beaker, and then pour the salted water into that second beaker and mix with the same spoon used for transferring it from the bottle (instead of the glass rod). That way no loss of powder on the paper and spoon handle.

[@BillSchwab]

greg7mdp2 Good idea Greg. However, the loss of powder on the spoon and paper is pretty minimal, but yes... there’s always a better way. I appreciate the input.

Good to see Curtis!

THX for the explination! I like it how You explane and I will try it as You showed! THX from stefan👍👍👍

[@BillSchwab]

Thank you, Stefan! I hope it works out OK for you! Keep me posted.

[@mikecastles]

Great instruction video, glad Curtis was 'helping' pickup the mail with you. Seriously, nice work and should help a lot of folks. I always get nervous when mixing up the palladium salts.

[@BillSchwab]

Thank you, Mike! Yes... Curt looks for any and all reasons to go to the mailbox. ;)

[@johnsimmons5056]

Great video...like the drone intro over your workshop. Are those all palladium prints on your desk ?

[@BillSchwab]

Yes. Those are all palladium prints. A couple of them have gum bichromate overlays as well. Thank you!

[@wyopobo5339]

Nice video. I'm looking forward to see the printing.

[@BillSchwab]

I’ll get to that pretty soon. If you subscribe, you should get notice. Thank you!

[@fotomuvesz]

My questions: what is the temperature of the water on the small hotplate? Isn't it better to start the solution in warm water? How many degrees did you heat the finished solution to so that it dissolves better?

[@rockanchor]

Thank you Bill. Will you do one for Platinum too. Sometime?

[@tareqzurooq7180]

Thank you so much

I also have a saddle back GSD... and also refine precious metal from scrap! Only difference is I'm in the tropics. I hate it here. Grew up in New England... planing on moving back. My dog needs space to roam and I need to get away from public. 😂

[@hanshabel9100]

Hello Bill, how long can the mixed solution Palladium chloride + Sodium chloride + water mixture be used.

[@BillSchwab]

Hi Hans, Great question. As long as you keep the solution in a tightly closed, brown bottle, it should last forever. If for some reason it dried out, you could use the powder remaining to mix again. Thank you!

[@F1lmtwit]

So, once mixed how long does the solution keep? Should it be kept refrigerated?

[@BillSchwab]

As long as you keep it in a tightly sealed, brown bottle, it should last a long, long time. It is the ferric oxalate that you mix with the palladium solution that times out after a couple of months. The palladium should be good forever.

[@F1lmtwit]

@@BillSchwab - Thanks - 2 questions (A) the mix above calls for Sodium chloride at 1.6 gm, but in the video (6:44ish) you say 2.0 grams. (B) When heating the palladium after mixing, what temperature and for how long?

[@BillSchwab]

Hi Jeff, Thanks for pointing that out. I tend to go with the 2 full grams and I don't notice any differences. Basically the salt makes the solution dissolve better and I don't think the extra does any harm. As for heating, I use a coffee cup warmer with a beaker of water in it to place the mixture in it's bottle. 120 to 140 degrees should do. Again, this helps with speeding the dissolve.

[@lhuhnphotography]

Hi Bill, I just watched this video several times and I am confused about how y h palladium you are using and what percent solution you are making. At one point you seem to say 2.5 grams of palladium and then later I think you say 2.3 grams. Can you please clarify? What percent solution are you making here?

[@BillSchwab]

Hi Larry. Sorry for the confusion. Follow the formula in the written description which is 2.3 g. 2.5 won’t hurt. You’re going between a nine and a 10% solution. Personally, I go on the lighter side because I don’t see much difference and I am just frugal.

[@lhuhnphotography]

Thanks Bill. That clears it up. I have been using the Palladium #3 (15%) for NA2 but you seem to be doing pure palladium prints. I have a decision point now regarding percentage before I mix.

[@BillSchwab]

@@lhuhnphotography I understand completely. Maybe you could mix up a small amount and see how you feel about it.

[@lhuhnphotography]

Bill, are you using straight FO or FO with Potassium Chlorate with the 10% palladium?

[@BillSchwab]

@@lhuhnphotography hi Larry. I just use the straight Ferric. I don’t use any of the potassium chlorate, contrasting agent. Unless I’m doing in-camera negatives, I don’t do any contrast control other than through the negative.

[@Puresniper1000]

Do you mix your own ferric oxalate Bill?

[@BillSchwab]

Hi Gary, I usually order mine from Bostick and Sullivan. Previously in powder form which I mixed myself, but now most often premixed. Bostick will sell it as "dry packs" that are remeasured into 25mm bottles. My trick to mixing is to add you distilled water and leave your bottle in a beaker with some water heated on on Coffee cup warmer. Keep shaking it ever so often to suspend undissolved powder until it clears.

[@Puresniper1000]

@@BillSchwab thanks Bill

[@stealthvanlife6867]

Hey Bill, fantastic videos on the Pt/Pd series. I have been buying the solutions pre-mixed, but now I know how to mix it myself, so thank you. How long do you leave the mixed sensitizer in the warmer bath? Also in the notes, you list 1.6g of salt, but in the video you used 2g. Which is correct? - Also, you have my vote on mixing the Ferric Oxalate next.

[@stealthvanlife6867]

Hi Bill, just checking in again to see about the discrepancy between the 2g vs. 1.6g as stated above?

[@fotorat]

I see you're getting your palladium from Signa Aldrich?

[@donnelson2250]

Thats an Artcraft Chemicals label on the incoming box. today's price has increased to $56.65 gm up from $49.00 last week. B&S is at $65/gm.

[@stealthvanlife6867]

@@donnelson2250 Do the prices change all the time? The reason I ask is that I may want to time my purchase or only purchase in small 10g to 20g amounts to average out my overall costs.

[@donnelson2250]

@@stealthvanlife6867 Spot market prices change all the time, but Artcraft and B&S change slowly - likely because they buy a coin and then convert it into powder needed to make the solutions. So change comes slowly to their prices
