You said its 1/2 in x 1/8in x 1/4 in and weighs around 2 gram if thats the case its aluminum. Melted soda  can. Like Outback said very common on beaches and camp grounds.

homefire, golddigger1950, or some of the other technical minded folks can give a better/more complete/more scientifically accurate answer, but basically it has to do with mass/density, area, reflective shape and conductivity.   When you melt the aluminum can you change is density, shape, and reflective area---that in turn changes the signal returned to your detector....different signal qualities means it processes differently in the internal electronics.    If you take your aluminum can and cut it into different sized pieces and then bend, mash, mutilate, and otherwise deform some of those pieces, you'll find you get different signals from them, too (and you're not making as radical of a change as melting them).

Theres probably a test to see if its Platinum, do some more research in your area, contact a Platinum mine......DW

  Indeed.  I have seen little pieces of a can come up as foil/nickel while bigger pieces come out as a silver dollar.  Aluminum can id as everything but iron IMO.

  Although I certainly wish you the best of luck with this, the odds of that being platinum must be close to .00001%

 Idea Because you say its from a plantation.
It could be silver. Try Homefire's method to test it (Taken from "is it silver" thread in Todays Finds)



Quote:Posted by homefire
Silver in Nugget like gold form is most rare.

Silver can be confirmed with good old Selsun Blue Shampoo!

It turns anything with significant silver content the most cool Cobalt Blue.  Sulfides it real fast, and can be recleaned with the touch of aluminum foil and some salt.

Waiting for your Report:

 Great

 



Good Luck in finding out what it is Smiley

Okay, here's my non expert opinion. Smiley
If they were found at the beach, I would say they look like aluminum blobs that were formed in fine, dry sand, then smoothed by natural means.
I've found several similar objects in different locations, including my front yard.
Keep in mind that a silver dime is about 2.5gr. and platinum density is about double that of silver. Teach
Case closed?

A 1/2 inch object that weighs 1 gram is not platinum. Most likely it is aluminum. The smallest bullet I have ever used is a 95 grain hollow point. They are about 3/8" in length and 9mm (just over 3/8") in diameter. They weigh 6.8 grams.

Platinum is more dense than lead or gold and would weigh closer to 10 grams in that size.

It's all about that moment when metal that hasn't seen the light of day for generations frees itself from the soil and presents itself to me.
