Ok, this is my is the process that I did. I bought 12lbs of films off eBay for $45. I set up 2 2.5gal buckets, one had bleach(splashless) and the other had tap water. I stripped the films, and rinsed them in the water. It took around 7gals of bleach. Like 3gals of the bleach was regular bleach. I don't know if that matters at all.

After it was all stripped, I rinsed with hot tap water. Here's where I don't know if I did something wrong. I thought after the rinsing to get the bleach out of it, and to bring my ph to 7....that what I'd be left with is a white cloud of AgCl, but it was kind of grey with a hint of purple to it. I should've just stopped there, but I digress.

Then I put my handheld blender in the container, and as it was blending I added my sodium hydroxide. It turned black, and heated up like it's suppose to. I took temp readings frequently during the process. It got up to about 218°F, and the heat shattered my beaker. (That never happened before). I got it all cleaned up, and put it back in a new beaker. There was still some AgCl in the solution as specks that I could see, so I added more sodium hydroxide(smaller doses, and slower then before). Then I seen only black in the beaker.

Final step, or so I thought. My little blender was going in short bursts as I added my sugar(small and slow doses). Now I thought I'd be able to visibly see the silver fall out as I was adding the sugar. But, I couldn't see anything fall out, and to be honest I never seen really any kind of reaction happen from adding the sugar. Did I mess something up? I thought maybe if I just let it settle for a while I'd be able to see something, but it's been about 6 hrs as of now and I still see nothing.

P.S. I kept all my waste solutions because it is all white and cloudy. I'm thinking that it's AgCl, but I'm not real sure. Can someone please lend a hand to put me on the path to silver redemption. Thank you

Collect all solids, dry and melt. If white AgCl is present add soda ash. From 12 pounds around 50g is expected (losing business)

Thank you for the advice Lino1406. But what do I do about what I have going on now?

So, I am in no way calling myself an expert in the Lye Sugar method, in fact, I have my own issues based on this method (see my post on waste), but by total accident, I found myself, totally inexperienced in this method doing it. I did everything you stated, including adding Sodium Hydroxide until it turned black. It heated up as you stated, added sugar and .... nothing but a little steam, that's it. Added more sugar ... Nothing. Then i thought I had nothing left to lose and added more Lye. BAM! Started boiling and stood back. Really nice drop .. but scary. Moral of the story, do all the research you can and be careful. If It was me, I would add more lye and stand back (a little at a time) once it takes off no stopping it, before you realize it is taking off, its done

Hey! I have extensive experience in the processing of silver X-ray films by wet process. Medical pictures, which have been taken from 2010 to the present day, contain no more than 4 grams per kilogram, which is approximately 2 grams per pound. You did everything correctly, you had to use heat-resistant dishes, the reaction of reducing silver with alkali and sugar is exothermic. I use other methods of silver withdrawal.

I have always used a mixture of borax and water always had good results
