A variant of the traditional cala positioning system used with a pointing frame, documented for transferring measurements in bas-relief.
Cala a spingere is a specialized variant of the cala documented by Le voci del marmo in the sequence devoted to pointing a bas-relief with a frame (telaio).
The phrase literally means a “pushing cala” and identifies a particular working arrangement within the traditional measurement-transfer system.
Etymology
Italian: cala + a spingere, “to push.”
Sculptor Notes
This term should remain linked to Cala rather than replacing it. It records a specific shop solution to the geometry of relief, where depth must be transferred from a stable frontal reference field.
