Interesting Beach Finds

[sphillips]

Found the following at about a foot down in damp sand, no corrosion on any of them. Item second from the right is much more dull in finish than the other 3. Don't think they are silver, no tarnish. Any thoughts?

melted aluminum?

 

[toddbbq]

Bonfire melted can slaw

 

[cudamark]

Yup, fire ring nuggets.....

 

[Digger_O'Dell]

Salt or fresh water? Salt will destroy some metals like zinc more so than others like titanium. Heavy or light metal? Hard or soft? Too many variables to even guess just by the pics.
I did find a lot of pieces like that in Florida, identified later by a local as probable pieces of the shuttle that blew up as they are very common there.

 

[toddbbq]

Did not think of titanium etc.. space shuttle remnants but you located pretty close to cape Canaveral

 

[ron lord]

are they lite or heavy ?

 

[RTR]

Interesting find ! I've seen melted aerospace pieces that look just like them.

 

[sphillips]

Found on N. Hutchinson Island, did not think of spacecraft remnants. They are relatively light in weight. Found close to the water at low tide.

Thx for the suggestions

melted aluminum.

Try specific gravity testing to determine the metal.
You will need a gram scale that will read .01 gram.
To find the specific gravity:
weigh the object in air, weigh it in water.
divide the difference into the weight in air.
the result is the SG and can be compared to the table at:
https://www.engineeringtoolbox.com/specific-gravity-solids-metals-d_293.html

In weighing the object I hang it from a metal gallows and thread on the scale for the in the air weight. The scale is zeroed out with the gallows and string on the scale before hanging the object from the string.
Then I fill a small pill bottle with the water and while holding the bottle locate it so I can raise the bottle submersing the object in the water. Do not let the object touch the side of the bottle or rest the bottle on the scale, it must be held to obtain the weight in water of the object.

A simple chart for what we look for:

Metal	Density
Gold	19.3
Silver	10.5
Platinum	21.4
Palladium	12.0
Copper	9.0
9ct	10.9 to 12.7
14ct	12.9 to 14.6
18ct Yellow	15.2 to 15.9
18ct White	14.7 to 16.9
22ct	17.7 to 17.8
Sterling Silver	10.2 to 10.3
950 Platinum	20.1

Note: the SG differences in gold and the different K (ct) of gold. This is due to the the various alloyed metals in the pure gold having different SGs themselves.

Thx walker, will need to get a gram scale. I think probably melted aluminum as others have offered, but would be interesting and fun to do as you described.

Melted silver from a shipwreck that went down from a fire!!!!!

If you believe that, I have lots of them to sell you! Only $5 oz, plus shipping. How many lbs would you like to buy? Here's a few to drool over......

So what is it

 

[cudamark]

Melted aluminum cans that have been tumbled in the surf.

I agree,silver would have been blackened

I find absolutely loads of them on a local beach near me...they are a pain in the ass!
