Stradivarius - Construction

Construction

While Stradivari's techniques have long been up for debate and not fully understood by modern craftsmen and scientists, it is known for certain that the wood used included spruce for the top, willow for the internal blocks and linings, and maple for the back, ribs, and neck. There has been conjecture that this wood was treated with several types of minerals, including potassium borate (borax), sodium and potassium silicate, and vernice bianca, a varnish composed of Gum arabic, honey, and egg white. He made his instruments using an inner form, unlike the French copyists, such as Vuillaume, who employed an outer form. It is clear from the number of forms throughout his career that he experimented with some of the dimensions of his instruments.

A recent study in PLOS One found no significant differences in median densities between modern and classical violins, or between classical violins from different origins. These results suggest that it is unlikely classical Cremonese makers had access to wood with significantly different wood density characteristics than that available to contemporaneous or modern makers.
