Techniques of manufacture
Modelling
Modelling is the most common and simplest technique. It is also used for the realization of bronzes: the prototypes are made out of raw clay. The small sizes are directly worked with the hand. For the larger models, the coroplath (or κοροπλάθος koropláthos, manufacturer of figurines) presses the clay pellets or wads against a wooden restraint.
Molding
The mold is obtained by application of a bed of clay or plaster on the prototype. Simple molds, used by the Greeks of the continent until the 4th century BC, are simply dried. Bivalvular molds, borrowed by the insular Greeks from the Egyptians, require cutting to obtain an obverse and a reverse, with which "keys" are sometimes associated protuberances allowing the two parts to fit better. When the piece becomes complicated, with important projections (arm, legs, head, clothing), the craftsman can cut out the mold in smaller parts. The piece is then dried.
The second phase consists of applying a layer of raw clay inside the mold, which can be incised beforehand in order to obtain effects of relief. The thinness of the layer varies according to the type of object to be realized. The faces of the mold are joined together, the object is then unmolded, and the craftsman can proceed to the final improvements, typically smoothing the junction. The craftsman also creates a small opening, a vent hole that allows steam to escape during the firing. The vent can also be used for assembly, allowing intervention inside the piece. The limbs are then joined to the body either by pasting them with slip, clay mixed with water, or by mortice and tenon joint.
Tanagra figurines were a mold-cast type of figurine produced from the later fourth century BCE, primarily in the Boeotian town of Tanagra. They were coated with a liquid white slip before firing, and were sometimes painted afterwards in naturalistic tints with watercolors, such as the "Dame en Bleu" ("Lady in Blue") at the Louvre. Tanagra figures depict real women, and some men and boys, in everyday costume, with familiar accessories such as hats, wreaths or fans. They seem to have been decorative pieces for the home, used in much the same way as their modern equivalents, though unlike these they were often buried with their owners. Some character pieces may have represented stock figures from the New Comedy of Menander and other writers. Others continued an earlier tradition of molded terracotta figure used as cult images or votive objects. Typically they were about 10 to 20 centimeters high.
Firing and completion
The piece is then fired in the kiln, with temperature ranging from 600 to 800 °C. Once the figurine is fired, a slip can be applied. The slip is sometimes itself fired at low temperature. In the beginning, the range of colours available was rather limited: red, yellow, black and blue. From the Hellenistic era on, orange, pink mauve, and green were added to that repertoire. The pigments were natural mineral dyes: ochre for yellow and red, coal for black, malachite for green.
