Renaissance Potters Were Nanotechnologists

Roland Piquepaille writes "In this article, Nature says that "tiny metal particles give 15th century Italian ceramics lustre." Nature adds that iridescent glazes -- changing colour when viewed from different perspectives -- were achieved by using "particles of copper and silver of between 5 and 100 billionths of a metre across." And the story becomes even more interesting. Nanotechnology meets alchemy! "The ability to change colour was regarded as an alchemical property, making iridescence magic too." Read this summary for more details. And for more information, you can read the abstract of this research paper, "Copper in glazes of Renaissance luster pottery: Nanoparticles, ions, and local environment," published by the Journal of Applied Physics."

Stradivari is the most famous because he made a crapload (almost 700 surviving, god-knows how many produced) of instruments.

He paid an unusual amount of attention to the shape of the scroll, the varnish, and other aspects which may or may not have had an impact on sound. But the theories like the one quoted above are nothing but romanticism. (Kind of like the ones that describe ancient Italian potters as "nanotechnologists").
