A powered polishing machine used with abrasive and polishing attachments to bring stone surfaces to the desired degree of smoothness and sheen.
Lucidatrice is the Italian term for a polishing machine. It appears among the machinery of the Pietrasanta marble workshop documented by Le voci del marmo.
Depending on the machine and attachment, it may be used with abrasive pads, stones, cloths, or polishing compounds during the final stages of surface preparation.
Etymology
From Italian lucidare, “to polish.”
Sculptor Notes
A lucidatrice should reveal a properly prepared surface, not rescue a poorly prepared one. Deep scratches left during earlier stages often become more visible as gloss increases.
