Stradivari and Guarneri treated their wood with mineral solutions (borax, sulphates, salt, alum, alkali), producing chemically distinct tonewood.

**Most likely** Answers **1** questionPublished0

## Where it stands

**Most likely** Its tests partly supported it: three pieces of evidence for, none against. It needs two reviews to be accepted.

## What it predicts

- Elemental profiles of Cremonese wood differ from natural and modern tonewood in ways ageing alone cannot produce.
- Consistent treatment signatures across instruments of a maker.

## What would rule it out

- Elemental differences fully explained by ageing, restoration or contamination in a controlled comparison with aged untreated wood.
