2005 EXPEDITION: YAMASH-I-T-A ( JAPS) TREASURE
To Buboy,
For all types of metal, either in ingot or bar, it can easily be determine using s. g. test. This will not lie to you. Remember our old physics lesson? All kinds of elements have specific gravity, and it is the identifying factor to determine what it is. This is true to all base metal or any element.
But... an alloy is different. it is a combination of different metals to form a new type of metal.
Example:
Using your object with an approximate volume of 192 inch cube, having a weight of approximately 28 kilograms, if it is an alloy, the distribution of different metals will be as follows:
1. Platinum = 25% --- 7.00 kgs. 19.5 inch cube
2. Titanium = 20% --- 5.6 kgs. 76
3. Nickel = 27% --- 7.56 kgs. 51.7
4. molybdenum = 27% ---- 7.64 kgs. 45
_________________________________
99% 27.8 kgs. 192.2 inch cube
Theoretically, this will give you 99% (+/- 1%) = 27.8 kgs. with a volume of 192.2 inch cube.
But for a true platinum bar, a volume of 192 inch cube will give you (again) 67.33 kgs.
As I recheck your picture, I noticed the end of having a "cut" where I assumed a piece has been taken for assaying. Logically speaking, all those who assayed it, will do all they can to have this object from you, but since they are also unsure about its identity, cloud of doubts are hindering their intitiative to have this metal. All they can do to prove to themselves that it is a true PT, is to put this into a more comprehensive assay procedures, wherein they will buy it from you at a very small amount, just in case they are wrong, then the money losses will be minimal.
I hope this will give enlightenment to you.
