Detector(s) used
Ace 250
I sent some samples to my buddy tman who has access to test equipment that will tell you what the metals composition is. 95% Zinc and 5% Lead. nothing to do now but keep looking.


I was at my in-laws last night in the country. I took some time to take the Ace250 out to a groove of trees that had a clearing in. The groove is right next to a small house that was for the hired men in its day. I found alot of trash items, nails, misc. steel, an old three pronged fork etc... Occasionally I would get a good nickel or dime signal and I would dig up these clumps of metal. I was baffled as to what they were.
A while later I got a signal and dug up the object that looks like a small bat, it is 1 1/2" long and 5/8" wide at its widest point. It occurred to me that someone had probably been doing their own casting at this spot. the "bat" appears to be aluminum.
What is odd here is that some of the clumps of metal were very light in comparison to other clumps relatively the same size. I broke some chunks off of the samples and some appear very dull in nature and they are the lighter samples. I am guessing that these are aluminum also. These are in the right hand pile.
The heavier ones are very shiny when samples are broken off of them. To give you a rough idea of the weight difference in the material, look at the "bat" and keep in mind its size 1 1/2"X5/8", it weighs 7 ounces. Now look at the small round sample at the top of the left hand pile in the picture. This sample is 3/4"X3/4"X3/16" at its thickest and it weighs 9 ounces. Less metal but more weight. None of the materials are magnetic BTW, and no rust.
Could I have silver here or lead, but it's not soft like lead. Anyone have any ideas. I have given as much detail as I can think of. If you want to know anything else that might help, let me know and I will try to do it. Thanks in advance.

Re: Mystery Metal, opinions please (with Picture)

Looks like old solder slag to me, like from casting or plumbing. The older stuff was mostly lead, but I think zinc also was used, or could be melted cans, you did say there was alot of trash in the area
 

Re: Mystery Metal, opinions please (with Picture)

I agree that is is probably lead slag. I've cast lead objects myself, and the oxidized lead and "scum" removed for the surface looked like that.

i pick up that stuff in my grandpa's field, both types.It is burn pile slag. usally more recent 20-30 years old.

That is a real possibility, there are several different burn pit sites on this property that I am aware of, who knows how many that I din't know of. Explains the melted look of everything, but doesn't add up with the aluminum cast "bat" I found.
 

Re: Mystery Metal, opinions please (with Picture)

The bat is probably part of a mortar and pestle. I would guess that from the light weight, it would be more for apothecary (pharmeceutical) use than ore grinding.
 

Re: Mystery Metal, opinions please (with Picture)

The "bat" could have been part of a drawer pull. Maybe they burned the house down when it fell into disrepair rather than tearing it down. All sorts of metals could be around those types of sites. -Noodle
 

Re: Mystery Metal, opinions please (with Picture)

Its hard to tell from the angle of the picture but your little "bat" looks a lot like a handle for a file or a rasp.
 

Re: Mystery Metal, opinions please (with Picture)

The bat could also be a handle for the rope or chain that went to an old fashioned overhead toilet tank. If it's aluminum it would survive the heat of fire up to about 1220*F Whereas the lead would be melted at about 620*F. Just babeling.

Yeap, definitely lead slag. I dig a lot of it and it looks exactly like that.

Good Guess, thanks.
 

I actually dont think it is lead slag. I dig PLENTY of lead slag at my Civil War sites and lead doesnt burn and blacken like that. I agree that it looks newer like fire pit slag from aluminum cans.

It's 95% Zinc and 5% lead.
