Curious whether the actual process for gold pressed latinum is ever mentioned. It's possible to encase a liquid into gold, but then you would call it gold encased latinum, rather than gold pressed latinum. Gold is neither very reactive nor absorbent, so I am not sure what pressing a liquid into it would do.
One way I could picture it is that gold is made porous (such as by loosely binding gold dust through heat), and latinum is contained within it. This could work if latinum were either very cohesive or very adhesive to gold - but the pressing process would still pose a problem, since gold is very soft, and a fine network of pores could be easily destroyed by pressure. Given that latinum is a liquid, this would also likely make for bars that are extremely fragile - unless latinum possess some quality that offsets that.
Anyway, I am not looking for a technically correct scientific explanation, just wondering if the makers of the series ever touch on anything specific about the manufacturing process.
