Two thousand years ago, the metal coating process is still difficult to transcend

Time: 2020-11--29
Artists and craftsmen  more than 2,000 years ago developed thin-film coating technology unrivaled  even by today's standards for producing DVDs, solar cells, electronic devices and other products. Understanding these sophisticated metal-plating techniques from ancient times, described in the ACS journal Accounts of Chemical Research, could help preserve priceless artistic and other treasures from the past. Gabriel Maria Ingo and colleagues point out that scientists have made good progress in understanding the chemistry of many ancient artistic and other artifacts -- crucial to preserve them for future generations. Big gaps in knowledge remained, however, about how gilders  in the Dark Ages and other periods applied such lustrous, impressively uniform films of gold or silver to intricate objects. Ingo's team set out to apply the newest analytical techniques to uncover the ancients' artistic secrets.
