Sistema dei compassi
A traditional pointing method that uses compasses and a network of reference points to transfer three-dimensional measurements from a model to marble.
Methods
Scultura da modello in scala 1:1
A method of producing a sculpture from a full-scale model, allowing dimensions and surface points to be transferred directly at the same scale.
Scultura libera
A model-independent approach in which the sculptor works the stone without transferring a full-scale model through a formal pointing system.
Copia da modello in scala ridotta
The enlargement of a sculpture from a smaller model, requiring proportional systems to transfer dimensions from one scale to another.
Foratura
The drilling operation used during roughing to create measured holes for splitting, reference work, dowels, or removal of stone.
Tracciatura
The layout operation in which principal measurements and reference lines taken from a model are marked directly onto the marble block.
Piano di appoggio
The prepared bearing plane or base surface on which a sculpture stands during carving or in its final position.
Riporto dei punti
The transfer of measured points from a model to the stone during traditional copying or enlargement.
Ritocco
A localized corrective refinement made late in the carving process to adjust detail, transition, edge, or surface without broadly reworking the sculpture.
Scelta del blocco di marmo
The selection of a marble block according to dimensions, structure, veining, defects, orientation, color, and suitability for the intended sculpture.
