Tropical Fish, bottom left I'm unsure about.

Thanks for that info!
Recently came upon some vintage resistors, thermistors, for a moment I thought the ones on the right were resistors too! I'll determine which contain the good metals....
You're correct! Scholar :))
Now I've found some other wires that are also the same. Thank you so much.
Not Zinc, zinc is brittle. Non magnetic so not Nickel.
Doesn't look like Alu, not as malleable, and different oxide coating, where the screws rubbed it is VERY silvery.
I've no idea what it could...
Also got some strips of what I believe is Zinc. Pretty happy about that.
~70 years old, so no major silver contacts
Around WW1 and WW2 time there were economic problems, so silver had a higher value, and shortages, also copper was mostly good enough for the job.
Looked...
I don't sell my recovery's to scrap yards or other dealers.
My plan is to process all of these things my self.
I'm not a fulltime scrapper, just scrapped a few bits of junk lying around (my...
Yep, check out my profile picture :)
Wanna be careful handling them too, be sure to wash your hands - and reduce contact to a minimum.
Cadmium is a pretty cool element, and I plan to extract it...
So they can be coated with silver. And I suspect Tin, though I've not processed my yet to confirm this.
Looking through my random contacts, some did not melt the way I would expect Tin to, or turn...
Great info.
Mine was just a large wall panel system not associated with any doors.
Yes, you are correct some Mercury relays looks similar to the oblong relay in the first picture - but they are clearly marked as containing Hg.
And all scrappers should already be well versed in...
Today I discovered Reed Switches. Realised I'd saved one.
Thought it was a fuse and only clipped it off to keep the nice long glass tube, it broke, but the tube was mainly intact.
Hoping to use the...
They are fairly round.
They are very easy to open - you pry the top off with pliers. While the switch is still mounted on the board, the base will remain there.

Inside that little switch (just under 10mm square) are two gold balls, probably only electroplated.
There are two tiny springs aswell,...
What I've found so far breaking resistors. Most contain a white ceramic interior.
But many resistors with flat ends have a darker material inside sometimes with a wire coil.
This leads me to...
Today I was in my rubbish bin, and noticed this little Blue Tantalum hiding inside of some heatshrink!
It was on the back of a power switch....
Interestingly this had a Sony Trinitron Tube inside.
They were the best you could get. Not surprising, as IBM are high quality guys.
Lots of Tantalum Capacitors.
Unfortunatley I had this guy...
A few more with some context.
A. big old switch
B. some kind of relay, two huge contacts, and 3 little balls on other side.
Rest is from an old washing machine (70's/80's/90's)
Scrapped a...

I accidentally broke one of these open, and out poped a yellow/tan MLCC.
Tried a few more, but they did not contain the same.
I've a...
Don't melt these silver contacts they contain 12% Cadmium - it becomes a gas at 650 degrees Celcius. Wheres the melting point of silver is 950ish degrees Celcius.
Try not to handle them either, and...
Hot water heaters can have a long Manganese rod inside - it prevents corrosion or something.
Not sure if they are high value.
Sorry, I should have taken some pictures of the switches before I recovered the contacts, for context.
I can often bend the copper to prize the contacts free without touching them.
Sometimes I...
Great info. Thanks.
Non magnetic, I don't have an acid test kit handy. Will try some other household chemicals to see if there is any reaction.
I placed it in some Cloudy Ammonia and it began to show orange corrosion.
