Along with Andrea Amati and Andrea Guarneri, Antonio Stradivari dominated the so-called Golden Age of Violins (roughly 1660 to 1750), and the instruments they crafted remain the gold standard today in terms of acoustic quality. World-renowned cellist Yo-Yo Ma has long favored a Stradivarius instrument, as does violinist Joshua Bell. But scientists have been arguing for years about precisely why these instruments have such superior sound. A recent paper published in the journal Angewandte Chemie confirms a theory dating back to 2006: the secret lies in the chemicals used to soak the wood, most notably borax, zinc, copper, alum, and lime water.
Good piece - if it was indeed the treatments, good luck reproducing that!
