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.
They discovered that gold- and silversmiths 2,000 years ago developed a variety of techniques, including using mercury like a glue to apply thin films of metals to statues and other objects. Sometimes, the technology was used to apply real gold and silver. It also was used fraudulently, to make cheap metal statues that look like solid gold or silver. The scientists say that their findings confirm "the high level of competence reached by the artists and craftsmen of these ancient periods who produced objects of an artistic quality that could not be bettered in ancient times and has not yet been reached in modern ones."

that is it everyone knows the annunaki were here for the gold so i am sure they were doing this layering so people wouldnt notice just how much gold they were taking
Iron Pillar of Delhi.
Thought everyone knew they took it; they used it to pave the streets of Heaven.
That is actually a metaphorical exaggeration, as the “streets” were actually the wiring of their Information superhighway.
And I almost flunked eighth grade art. I made a pancake out of clay. The teacher said I lacked creativity.
In my opinion the greatest artists engage realism and the ones that can’t or won’t embrace realism embrace creativity.
“It also was used fraudulently, to make cheap metal statues that look like solid gold or silver.”
Who’d a thunk the advent of “100% gold plated” costume jewelry was invented 2000 years ago? Bet they didn’t have “100% cubic zirconia” to set in their gold plated rings.
That was yours?!? I broke a tooth on that thing.
Google the 50,000 year old spark plugs found in CA during the late 1960’s, it will blow your mind.......
Here is the link to a History Channel story on the spark plug, with photo’s starts at 4 minutes in, http://www.youtube.com/watch?v=ZR86JqKP8BQ&sf=Relevancy#1
Alien technology.....they took the secret with them when they left.
Maybe you must missed breakfast that day. :-)
She was going to flunk me because I lacked creativity. So I rolled up my pancake and told her it was a snake. She threatened to flunk me again. So, I took the clay and made a functioning nuclear reactor. She gave me a C because “It isn’t aesthetically pleasing”. Well, Jeanie Adams sculpted a horse that looked like a terrier dog and she got an A. She was a teacher’s daughter. The fix was in.
