    Silver or Aluminum?

    Any ideas on how a layperson can tell the difference between a chunk of Aluminum or Silver?

    Found this piece on the beach today...

    Have I found a beer can that got too close to a fire or a Spanish silver nugget?

    Re: Silver or Aluminum?

    is it heavy or light for its size, also you could do a specific gravity test

    I'd call it heavy for it's size, but it's not very big, so it's very hard to tell... I've attached another image with a dime for scale.

    Maybe a jeweler could tell??

    Re: Silver or Aluminum?

    I found something a few days ago that looks just like that. it came off of a construction site and seems light so i'd go with a hunk of melted aluminum. I went outside this morning and the workers had started a fire out of anything they could find to keep warm and i saw they had thrown a hunk of aluminum siding in the fire. (probably just to mess with me in a year or two )

    BTW......anyone know the name of those silvery layered rocks that you can find in red clay?

    is it soft? Can you bend it? If heavy it is lead. If so go wash your hands. You do not want to handle lead and then eat food.

    Probably solder from an electrician.

    If it is solder then technically there is some silver in it probably.

    Re: Silver or Aluminum?

    I was recently over on the east coast and was talking to so other hunters and they were telling me about how they have found Titanium, from the Challenger shuttle.

    Now you have three choices. Did you clean it? It looks pretty bright.
    If it was aluminum from a fire I wouldn't expect it to be so clean.

    Good Luck and HH

    Take a knife and press the blade in it, if it mark REAL easy it's lead, some what easy aluminum, hardly at all silver or such.

    Re: Silver or Aluminum?

    Whenever there is a large campfire, someone is going to throw their aluminum soda or beer can in the fire. It will melt and eventually burn away. Usually the fire will not be hot enough, long enough, to completely burn away. I find melted pieces of alum like this wherever there was a campfire. I don't know why it is so shiny. Silver is not shiny either after exposure to salt. Maybe the waves polished it.
    I made a test solution by mixing nitric acid, a pinch of potassium dichromate, and a little distilled water. Here is a site on test solutions: http://shoreinternational.com/TestGoldMakeSolution.htm

    Re: Silver or Aluminum?

    I don't know why this link for silver testing is not com ing up. I will have to type some of it from my copy.
    To Test
    File a notch in test piece, apply a drop of solution- watch for color reaction.
    Brass--Dark Brown
    Copper--Brown
    Gold--None
    Nickel--Blue
    Lead--Yellow
    Tin--Yellow
    Silver(pure)--Bright Red
    Silver .925--Dark Red
    Silver .800--Brown
    Silver .500--Green
    Palladium--None

    I used this Nitric Acid/Potassium Dichromate/Water solution to test a large piece of metal i found on Treasure Beach. It showed yellow, and turned out to be lead sheathing from an old ship. It worked good on silver too ( Dark Red). I will have to try it on Aluminum.

    To Test
    File a notch in test piece,

    A) AHAHAH, not if it is of value, look for an unexposed spot and remove any finish, then apply the test soloution.
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


    apply a drop of solution- watch for color reaction.

    A) Wait one minute, check the color of the soloution, wipe it off and check the color/mark on the metal for the following color.
    `~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    (start) ( after one minute )
    Brass--Dark Brown --------------------------light brown
    Copper--Brown--------------------------------cleaned copper
    Gold--None-------------------------------------none
    Nickel--Blue------------------------------------scarcely any
    Lead--Yellow----------------------------------leaden
    Tin--Yellow------------------------------------dark
    Silver(pure)--Bright Red-------------------grayish white
    Silver .925--Dark Red----------------------dark brown
    Silver .800--Brown-------------------------dark brown
    Silver .500--Green--------------------------dark brown
    Palladium--None-----------------------------non
    Platinum--Vandyke brown---------------none
    Iorn --various -------------------------------black
    Zinc --light chocolate---------------------steel grey
    Auluminum---Yellow ---------------------no stain

    A) then wipe the soloution off and look at he spot left on the metal.

    A I appologize for injecting the wiped off colors in your excellent post.

    Re: Silver or Aluminum?

    Realde, Thanks for the wiped off colors chart; I will print this and save.
    Yes, do not file something of value, look for an inconspicuous spot. Wash off when finished.
    I love that bright red color of pure silver.

    jwvanno2, mix up a small batch. Test a spot. And look for that pretty red. I'm afraid it looks like aluminum to me. Let us know

    Nitric acid will sure clean copper! I use it sometimes before soldering a very corroded copper pipe or brass radiator.

    Jose , Do you make a living tilting windmills, or is it a hobby.
