What about.... tin foil
Ever wonder why tin foil has a smooth side and a shiny side?
Me too.
So........... drum roll please!
The reason aluminum foil is shiny on one side and dull on the other is rather interesting. Aluminum foil is produced by rolling it between successive steel rollers. Each set of rollers squeezes the foil thinner. The last stage of rolling reduces the foil's thickness to a thousandth of an inch or even thinner. The problem is that such a thin foil is too easy to tear during the last rolling stage. So, for the last stage of rolling, two sheets of foil are placed face to face and passed though the final set of rollers together. Since the steel rollers are highly polished, the foil faces that contact the rollers are also embossed to a highly shiny surface.
After rolling, the resulting sheets are separated from each other. The surfaces of each foil that had faced each other are matte in texture, since they had only been squeezes against each other, and not the polished rollers.
just thought you ought to know!
