At the end of the Deep Space Nine episode "Who Mourns for Morn?", Quark thinks he's found a hidden treasure, a vault filled with bars of gold-pressed latinum. But before he can gloat and revel in his victory, he notices something horrible: all the latinum is gone, leaving behind nothing but "worthless gold!" In a sudden fit of rage/frustration, Quark breaks some of the bars, and they shatter and crumble like dirt clods.
The problem is, real gold doesn't work that way. It's one of the most malleable substances known to man, if not the most. A big, thick bar of it would bend, not break, and certainly not crumble!
This leads one to suppose that the bars are something other than pure gold. Has there ever been a canonical explanation given for what makes de-latinumized bars of gold-pressed latinum have wildly different physical characteristics than gold?
