I only have two left for this "season" (including the one coming out on Friday) but we're in talks about doing more down the line and Ilfosol 3 has come up in discussion. 🙃
I pour my spent fixer (and blix) into used 4l washer fluid jugs, label it clearly as spent photographic fixer (or blix) and hand them in to my local waste disposal facility. Luckily, it's free to deliver household waste - including used photochemicals - where I live.
13:25 what I like to do is pour everything into the tank and put the leader into the little pool of fixer that will form on the top of paterson tanks. This will give me an idea of how strong the fixer is while the film is fixing. Also I have a question, if I have tried to extract the silver, what can I do then. I wouldn't trust that my method actually removes all the silver.
@@Shaka1277 thanks for the reply. It shouldn't be a problem as I don't think it costs anything here in Sweden to give chemical waste to a recycling center. Edit: yes I just looked it up an appearently photographic fixer here is concidered "dangerous waste" (very specific description I know) either way what I found said that you can just give it to recycling stations as long as it is properly marked with what it is. And I know my local recycling station does have a place were you can leave "dangerous waste."
There are a few ways but the simplest / most accessible is dumping steel wool into it. This replaces the silver ions with iron irons and iron metal with silver metal. The silver-coated wool can go into the bin (silver is only a problem as an ionic salt - at home scale) and the iron-soaked fixer can then go down the drain! There are some good guides out there with specifics but it works really well.
@@Shaka1277 Thanks for explaining. That doesn’t even sound hard to do. Is there an easy way to tell when the process has completed? It’s amazing to me that the manufacturers don’t give any information to home developers, yet they must be aware that a large portion of there customer base is developing at home and pouring the spent chemicals down the loo. It’s like the industry’s dirty secret… literally!
Literally, yeah! There isn't really, but I've seen many people say that two standard "clumps" or steel wool is usually enough for 1 L of spent fixer. I've no idea about any home brew test to check for residual silver but there are kits you can buy if you want to be absolutely certain.
In USA many counties, as in practically all.... low volume users can pour down the drain... you can be conditionally exempt if your less then 220 lbs. of effluent per month. thats about 22 gallons.
would love if you did a video on an acetic stop bath like Kodak indicator stop
Great video man! Heavily underrated channel. Would love to see a video like this with Ilfosol 3.

Really really good. I learnt a lot watching this. Much appreciated.

Neat idea about the leader! If you don't trust that your silver extraction was thorough, still treat it as contaminated waste.

This is great. Very informative!
how does someone de-silver the used fixer at home?

Thank you for this
Well done!
