Description

0 – 63 µ, for violin makers

Luthier’s Pumice

The secret beneath the varnish of the Italian masters. Modern analyses of historic violins consistently reveal a sharp-edged, hydraulic mineral layer locked directly into the bare wood. This is Terra Pozzuolana—a fiercely hydraulic, volcanic pumice stone. Extra-finely ground and meticulously sieved, it acts as both an aggressive mechanical polish and an impenetrable structural ground, creating the perfect foundation for classical instrument making.
