[expand]Lost-wax casting was primary technique for creating complex ornamental forms. The process began with wax model shaped to final desired form—carved, molded, assembled from separate components. This wax model was coated with clay creating mold, then heated causing wax to melt and drain away leaving hollow cavity matching original wax form. Molten bronze poured into this cavity filled the space, cooling to create metal duplicate of original wax model. Breaking away clay mold revealed bronze casting requiring final polishing and detail work.
The technique allowed creation of intricate designs impossible through other methods—hollow spheres, complex interlocking components, elaborate surface patterns achieved through detailed wax carving transferred directly to final bronze surface. But each casting required destroying the mold, making each piece unique rather than mass-produced replica. This uniqueness enhanced value: the bronze ornament was not standardized commodity but individual creation embodying specific craftsman’s particular skill and artistic vision.
The sand casting was simpler alternative for less complex forms. The model was pressed into sand creating negative impression, molten bronze poured into this impression, cooling metal was removed and finished. This technique allowed creating multiples from same model, enabling some standardization while still requiring substantial finishing work ensuring quality final product.
The hammering and forging techniques shaped sheet bronze into three-dimensional forms—bowls, plates, decorative elements attached to larger structures. The smith heated bronze to workable temperature, hammered it over shaped stakes or into wooden forms, annealed the metal periodically to prevent work-hardening that would cause brittle fracture. This process required careful temperature control and rhythmic hammering creating forms through accumulated small deformations rather than dramatic single blows.
