This object was found at April 2010 and its weight is 1936 grams. It´s in good condition with only marginal weathering effects. There are some breakups with hollows behind. Its strange shape is typical for parts with a mass over 1000 grams. Small objects aren´t shaped in such a complex way.
Sensational Analysis Result
At first the sample sent to the Institute of metallurgy didn’t dissolve in sulfuric acid. Thus no chemical analysis was possible. Several experiments later a different acid was found that dissolved the sample while permitting further analysis of various iron oxidation levels.
Then, in February of 2013, something sensational was found that was previously unknown in the scientific community: Unnatural iron hydroxide.
Natural iron hydroxide is wide-spread. But this dissolves well in sulfuric acid and it is resistant to weathering. The material presented here behaves contrarily! There was no scientific explanation for this surprising fact.
However their structures are very similar. Although they both have accessory minerals like quartz and a few metal oxides embedded, there are three inherent differences:
This unnatural iron hydroxide contains:
0,2 % metallic iron
marginal traces of amorphous zirconium silicate
no porosity and no capillary water
