Sculptors employ a combination of meticulous techniques and material knowledge to preserve delicate stone features, particularly thin protrusions that are prone to breakage. The process begins with selecting the right type of stone—softer stones like marble or limestone are easier to carve but require extra care, while harder stones like granite offer durability but demand precision.

To prevent fractures, sculptors often reinforce thin sections with hidden metal supports or epoxy resins, blending these seamlessly into the design. Proper tool selection is crucial; diamond-tipped chisels and pneumatic tools allow for controlled, vibration-free carving. Additionally, applying sealants and periodic maintenance, such as cleaning and waxing, protects the surface from weathering and erosion.

Environmental factors also play a role. Displaying sculptures indoors or in shaded areas minimizes exposure to harsh elements. By combining craftsmanship with scientific preservation methods, sculptors ensure that even the most fragile stone features endure for generations.
