Selenium toner Kodak vs. Ilford

[bill2424]

I've always used Kodak in the past but do to short supply I will be switching to Ilford.Will there be a difference in dilution? I'm using Ilford multigrade fiber paper. I was mixing the Kodak 1 to 30 for 4 min. at 68 degrees.

I haven't had any supply problems. Freestyle has it in stock, though it's listed as "low stock - call" but every time I've done that on anything they've had it. They also have their store brand "Legacy Pro" that's the same formula. I use the Legacy Pro brown toner and would use the selenium without a second thought of I couldn't get Kodak.

(Select "Kodak" and "Legacy Pro" to narrow the field. Direct linking to the narrower selection didn't work.)

Or do you mean "short supply at a local store or my usual vendor?" That's perfectly legitimate of course, I just can't buy anything locally and forget some people can. Also, I know B&H wont ship hazmat and I'm not sure about Adorama. No problem with Freestyle. Freestyle doesn't list Selenium toner as hazmat anyway, but it seems an odd material where some places do, some places don't.

Thanks Roger. My local store has Ilford and I thought if it was similar to Kodak I would give it a try.

Worth a shot. If I could get Ilford locally I'd try it. I'll be curious what folks tell you.

Actually I shouldn't be so quick to dismiss buying locally. I think there is at least one supplier of traditional materials inside Atlanta proper. I'm a born in country, dragged into becoming a suburbanite now though, that won't venture into the city proper without dire provocation (which usually comes from my fiance who thinks I'm silly and lived in Brooklyn, but then I insist she drive...)

To possibly answer the original question:

Harmon (Ilford) Selenium Toner
from the MSDS

Ammonium Thiosulfate 10-30% by weight
Sodium Selenite 1-5% by weight
Water 50-70%

Not very precise in my estimation.

Kodak Selenium Toner
From the MSDS

Ammonium Thiosulfate 27% by weight
Sodium Sulfite 10-15%
Sodium Selenite 2% by weight
Water 55-60%

More precise. It is possible that the Ilford product has similar proportions and they just want to leave some wiggle room in the MSDS. I'm not sure what the addition of sodium sulfite does for the Kodak product, but I don't think much. I keep and replenish my KRST, and I'm fairly sure the sulfite has long been oxidized in my working solution. It works just fine.

I should add that the above figures are for the concentrate, not the working solution.

I've never done a side-by-side comparison of the two.

Hope this helps

B&H does ship Kodak Rapid Selenium Toner. They won't ship Indicator Stop Bath, but they will ship other stop baths, so I imagine that one is just because of the concentration.

Bill, check the shelf life once mixed.
Most Ilford Chems only last 7 days once diluted with water. Not sure about the toners, but worth a check. If you plan on going back in the darkroom for another session the following weekend, stick with Kodak Chems.

that's quite a statement, hadn't heard that before

That's an interesting question for me, too. I used Kodak rapid selenium toner a lot and was very satisfied with the results. It became very difficult to get this stuff here because it's quite poisonous. I used a different selenium toner instead (from Berg), which was supposed to be the same like Kodak but would give a fairly different hue of the prints. I use Ilfobrom FB Galerie. As far as I know, Kodak Rapid Selenium is something like 5% sodium selenide plus 30% sodium sulfite in water and should be fool proof to reproduce. However, my experience with that Berg toner indicated that there might be something else. Or they use a different concentration of the stock solution? Anyway, if you make any experience with that Ilford toner, I would be very interested in that.
