Pictures added Iodine Leach Test In Progress

[greatgems]

I have just started a test IODINE Leach

using

10% Iodine Solution From Drug Store 100ml Special order
1000 ml Water Distilled

Pyrex retangle Container with Lid 1.5 L

5 Peice of Silver Plated Vase .800 Copper .200 Silver i though this was a good start and test

No bubbler just straight solution

Very Dark Solution seems to be very strong lets see what happens

Will post Results on Silver and Gold and might even try Platinum and Rd

stay Posted want to know peoples thoughts

Solutions not that expensive for 1100ml or 1.1L of the solution it cost $24 cdn but from what i have read this might be to strong or very strong so might be able to add 400 ml more of water make it an even 1.5L of solution that can be used over and over again.

If I remember correctly,that bottle only has 1% available iodine in it.I may be wrong but look at the percentage of active ingredients on the back.

 

[greatgems]

It's 10% full bottle is active man it's strong can't see threw my mixture at the bottom of it is already silver flake today

Is it Providone-Iodine?

Medical grad tinicure ordered from drug store just say you are in the jewellery industry and using it for stripping silver and gold plated items they don't ask questions then you don't have to worry about them thinking you are creating drugs at your house

Please try to proofread your replies before submitting them.That way there is no potential misunderstanding in the future.....thnx.
I will look into the iodine.

Sorry iPhone is what i have been using. I find it working very fast already and moved the scrap to 2.7 litre Pyrex dish and added 500 ml of water bring it to 1.5L of water to 100ml of 10% iodine air stone added also now

I look forward to seeing your results. Please post pictures if you are available to. Even ones from your phone. As much as I learn from reading here a picture... well like they say, a picture is like a thousand words, or something.

First one is just my set up its a pyrex dish baking dish with lid and hole on top with air stone in side and hose going threw lid

Next is only about 36 hours later of a cut up silver plated vase the plating is flaking right off this is an excellent way to set up a leach leave it be and keep putting more stuff to deplate thanks

 

[greatgems]

This process seems to work better as the solution gets lighter and closer to water color process is excellent to just leave and let it work it's magic

Gol leaching is fast for passive leach I started a 500 ml of water and 50 ml of iodine threw some pins in some cell phone boards some connectors cell phone board was stripped when I woke up had it in for about 8 hours excellent process so pleased

Hello everyone, I am a newbie to any type of refining. I have about 10 lbs of plated antique silver items mostly silverware, bowls, candle holders and such. Some of the older items seem to have a good amount of silver. I liked this idea about using iodine leaching. Im interested in learning more about this technique and seeing the results form the leaching.

Thanks, Andy

Most of the chemicals used in recovery and refining are very dangerous in one way or another, and sometimes in several ways.

This is not always mentioned in every post, so while it may seem like instant fun and riches, there is way more to it than that.

Read the Safety Section first, and if you feel that you have the patience and wherewithall to apply all of the safety precautions, then take the Guided Tour and you will come to the download for the first refining book that you absolutely must read, in order to get anywhere with anything at all concerning refining.

If you don't fully regard the safety precautions, it's likely that you will shortly end up in the hospital or the morgue. That's just the way it is.

If you are sharp, and take all the precautions, you will have lots of fun, make some friends, and probably make some money at it in one way or another.

Welcome to the forum!

Thanks Eethr,
Safety is always #1, actually part of my full time job is Health & Safety and Quality Control. I have great respect for chemicals and would never attempt to try something Im not 100% sure of. That is partially why Im interested in the iodine procedure, I checked the MSDS on iodine and it was suprising how dangerous it is in at 100% non dilluted. I always thought of iodine as just a strong dissinfectant. I suppose it is when it's dilluted to .50 %.

I do have a few questions on the procedure.
1. What is an "air stone" I assume the small clear tube is directed outside for ventilation and gas build up egress.
2. What is the best way to capture the leached silver after the silver plate is removed? Coffee filter maybe?
3. Is silver iodine leaching any different than gold iodine leaching. Procedural wise?
4. How much silver is disolved into the leach and will it filter out or is another process necessary?
Thanks

I've never used that process, but maybe the original poster or someone else can help you.

Sorry for disappearing was in states fr few days going again tonight to California

But air stone is the thing that makes fine bubbles in a fish tank but after another test it's not needed at all


Just use 10% iodine but find cheapest supply you can put in large 2 to 10 litre pyrex dish what ever amount of iodine you use make sure it's 1 to 10 solution 1 part iodine 10 parts water use as much plated silver or gold you can

it really works well first 3 days most the silver and gold will drop it flake off make sure ever 5 to 12 hours up to you you move peaces around it let's the silver flake to bottom keep adding more and moe till all peices are stripped then filter out silver or gold flake with coffee filter add pure copper peices helps more silver and gold presipitate the only thing I'm finding out is if adding electric current will help presipatation any

Iodine is safe and smells a little but no dangerious gasses
keep covered or it will evaporate and you will loose your iodine which could be costly

Thanks

Iodine is not as benign as you might believe. You should be more careful, low odor doesn't mean safe.

Thanks for the update. Hows that leach coming along?

That MSDS it for 100% iodine, not 10% as called for in this process.
