The taste of fixer

[hadeer]

Quite a few years back I used to check if the paper was sufficiently washed by lifting the sheet from the washer, let most of the water drip off and then taste the last drops that fell off with the tip of my tongue. If there was fixer residue those drops had a typical taste and I had to wash some more. I have no photos from that time that show bad fixing. Anyone ever used the same method?(I use a chemical for testing nowadays)

I believe Van Gogh use to drink absinthe diluted with ink. I enjoy comments by mad artists.

I know a good way to check you blood sugar...

If it's sodium thiosulfate I doubt it'll do much to the body at all. Isn't it also used for tap water treatment?

If it's ammonium thiosulfate that might be different, but PE could probably answer more.

As a child I was told I was fond of dirt. I grew out of that... I think.

Funny how we seem to think that using our tongue for testing is just something we even consider.

Sodium Sulfite used to used to preserve meat IIRC. It tastes like a nasty salt.

Sodium NITRITE is used to preserve meat. A big difference…

Nitrites yes, but also sulfites (E222) though not for meat preservation.

Not a method I've tried, or considered.

Maybe you were confused by the fumes and grabbed, of, say, the bottle of gin instead?

That might also explain the memories about it you are having now.

Instead of tasting, I smell the wet print up close. I actually ran a test using the hypo HT-2 test solution n I am very close to smelling a completed wash.

I have no idea. But I recall quite a few times where I sipped a mouthful of Dektol while syphoning it. Tastes like Fish.

This is the quote of the day. I can only imagine this absurd session by session trial of how close Paul has gotten to sniffing out an unwashed print.

"Nope! This one needs *at least* 7 more minutes!"

I read a comment once either here or on LFPF about an old photographer, mentoring the poster, who used to taste the fixer itself to check its condition. Eventually, he turned blue.

This is quite plausible. There are several documented cases of people turning permanently blue from consuming colloidal silver.

Wasn't there also a member here who grabbed a bottle of fix or dev and took a swig, instead of grabbing his beer?

It was Sodium Sulfite, and in a tea cup.

IMHO, it included one of the most memorable APUG responses of all time (Thanks Murray ).

I would never ingest anything from the darkroom. Many things are quite toxic, and constant exposure can lead to a adverse reaction later such as contact dermatitis. Even if assumed somewhat safe, that washed print with lingering fixer could have cross contamination from the tray, or work surfaces, or spills from other toxic chemicals.

btw Did you know methanol, the stuff in lens cleaning solutions such as the eclipse brand, can cause permanent blindness if just 10ml of it is ingested? it goes straight to the optic nerve. 100ml is fatal. It's something people use routinely but don't think much about. Plus you can absorb it through the skin too.

You must be a blast at parties.

I guess it's a question of dose, like with so many every day chemicals. BTW the symptom you refer to is called Argyria.

+1 to that. While the active ingredient of fixer is most likely some form of thiosulfite, people tend to forget all the other chems either intentionally included in fixer for adjusting/buffering pH, for improving keeping properties and making the product more fool proof, or simply accumulating in the fixer from other processing steps. There's probably no reason for hysteria when we spill some on our hands but I wouldn't intentionally get any of that stuff onto much less into my body.

Isaac Newton stuck needles in his eyes, but there's no need to do it any more.

Same with drinking darkroom chemicals.

Never Never Never Ever test Monkhoven's intensifier this way, unless you have a lot of old Voigtlander lenses you wish to bequeath to me

 

[Nikola Dulgiarov]

Actually, I did taste water run-off from washing a print once, as a curiosity. The taste is quite characteristic, easy to spot. Although I would never suggest that anyone do that, I believe it is of no consequence as we're talking of ppm quantities of chemicals easily broken down by metabolism

 

[Helinophoto]

Doubt that tasting (not actually swallowing) and spitting out will cause any harm what so ever.

Never done it myself, so I am not sure how a badly rinsed paper taste like, I normally let them sit for 15-20 minutes in a large holding tray, then i shower them thoroughly with warm water, both sides.

If they are not clean by then, then to hell with it

Oh no, you're doing it all wrong!

... Waits for the next APUG flame war about archival washing ... :munch:

 

[Helinophoto]

Haha, none of my photos are worthy of existing beyond 5 years anyway.
- I also yell and swear at the prints now and then, just to let them know who's boss ^^

Besides, I can always make new ones.

If they become worth something after my death, too bad, not my problem

hard to believe people would make it a regular practice to ingest poisons ...

do you for other residual poisons the same way ?
arsenic? cyanide ? lye? selenium? ...
