Silver Solder

So let's say a fellow was cleaning out their garage today and found a rather large, and hefty, roll of #75 silver solder?

I don't know how "pure" silver solder is, it comes in various ratios.

Looking for info on home smelting.  Trying to extract a higher value alloy. 

Any ideas?  Good do it yourself tricks?

To be honest, I would suggest

To be honest, I would suggest you leave the smelting to the professionals.  The process is resource intensive and hard to do on a small scale.  You will make more money if you just sell it, AFTER you find its silver content.

You might take it to a few jewelers and see if they will give you a higher price than you would get at the refiners.  Use the proceeds to buy the pure stuff.

Just sell it

It has the best value just the way it is.  The trick is to find out what type it is, soft to hard.

If it fits in a flat rate box, I would eBay it.

It's "Hard" silver solder

It's the hard stuff.  Approx 13 lbs of it on four spools.  I think ~5% silver content. I see it retails for ~.25/inch or so. 

I'll try ebay, those folks will buy just about anything at a premium.

a local plumber might buy

a local plumber might buy it.  make a few phone calls get a value at home depot. 

I would hang on to it like any silver investment.  it will be easy to sell when the price is higher.

you have to get the correct % since 40% silver is worth much more than 5% silver.

yes, you are right, just be sure to note in your listing that it is undetermined or unconfirmed whether it is soft-med-hard. I think you may have hard because of the #75. here's a basic reference chart on silver solder

SILVER SOLDER

SOLDER   PERCENTAGE SILVER
Hard
Medium
Easy
Easy-Flo
  76%
70%
60%
50%

as far as determining hard-med-soft solder and therefore the total silver content,  use it and note the results (then color code ends for future use) and be sure to test the solder joint for durability.  you can also melt a bit of each in a kiln-must have an accurate pyrometer for this-and check for melt temp if you are not comfortable with trying it out. I wouldn't use it on a meaningful work in progress or on a customer's piece until until you know the results, tho!!!

so, please don't scrap or refine it and link to your listing if you list it!!!!!!!! :-D

Wow

Had no idea the silver content was so high.  That does make it an interesting find.  I think it's actually from my father's old store, he had an electrical/industrial controls company.  It's probably 40+ years old.

Thanks all for the info!

Motivated to clean garage

Yep.  13 lbs!  At least according to the bathroom scale. 

Good advice, I'll take some to a jeweler tomorrow.   This stuff is probably from the 70's.  It's wrapped in paper with twine wrapper on large cardboard tubes.  I found a bunch of copper wire on spools also. 

BTW,  I'm suddenly motivated to finish cleaning the garage.... 25 years of stuff in here, who knows what else!!!!

bless your dad's heart

quite a nice, unexpected legacy he left you

if you plan on scrapping the copper, be careful. because of all of the copper theft these days, if you can show that it is old stock from your dad's business, it may be to your advantage to do so and retain that proof (in case you need to explain to the authorities because whoever you sold it couldn't prove it wasn't stolen or was caught buying other stolen copper and gives you up as a sacrificial lamb). I'm not the most trusting soul these days, unfortunately. :(

ooow, you must have a fun garage, lol. yeah, dh says I'm a little strange.

40 years old, it's expired

It's 40+ years old? That's too damn old, it's not worth anything. Please send it to plunder and I can properly dispose of it for you.

Nice score, Captain. Also try looking up "metal recycling" near you. Here in Detroit they are as common as convenience stores, and they can offer remarkably different pricing depending on how crooked they are. Shop around, it's worth your while. Any of them will be drooling when you walk in the door with those spools.

The last time I cleaned the garage, I scrapped out an old broken stick welder that was given to me. The price difference between two scrappers (within earshot of each other) was over a hundred dollars. If you think that the bankers are brazen, you should meet some of the scrap metal dealers in Detroit. One of them stole three scrap car batteries out of my trunk while I was rolling the windows up and locking it.

What constitutes the rest of the solder?  Lead?

from that time period, I'd 

from that time period, I'd  say a mix of tin, zinc, and cadium. most current solder formulas have the cadium removed  because of it's cancer-causing properties.

Anyone know of a smelter...

...who will take sterling silverware, refine it into bars, and return it to you? (We're talking about 650 troy oz. here.) Or do you have to sell it to them to refine and then go buy your own silver bars or coins someplace else?

I've been using SilverTowne to convert Sterling Franklin Mint sets into bars.

I  don't know about silverware but I don't see why they wouldn't.

They are paying 94% on Silver content but there are various fees for the exchange. Still the best deal I've found to convert. Running 3-4 weeks for the turn around. http://www.silvertowne.com/

Good Luck!
