A testa di moro is a Sicilian ceramic head, and the listings that sell it are full of words that are obvious inside a workshop and not obvious outside one. Biscotto, cristallina, lustro, antichizzato, ornato. Here are fifteen terms explained in a line or two, grouped in the order you meet them reading a product page from top to bottom.
This is not a general glossary of ceramics. It is the vocabulary of this one object, and it is here so you understand what you are buying when two pieces that look similar cost twice as much as each other. The Italian words are kept because that is how they appear on the listings.
The body: how the piece is made
- Terracotta. The fired clay the body of the head is made of. Reddish or yellowish depending on the pit it came from, and porous until it receives the glaze.
- Biscotto, biscuit. The piece just out of the first firing. It is already hard and there is no going back, but it still drinks water and has no colour: this is the state in which it waits to be glazed.
- Applicazione plastica, applied element. A part modelled separately and attached to the body while the clay is still damp. Roses, lemons, beads, the points of the crown: everything that projects is born this way.
- Firmato a fuoco, fired signature. The signature is not written on the base with a marker. It is applied before firing, so it goes into the piece and cannot be removed. It is the first check on origin, and we cover it in how to recognise an authentic testa di moro.
The colour: what happens on the surface
- Smalto, glaze. The coating that turns to glass in the kiln. It closes the pores of the biscuit, makes the surface washable and carries the colour. When it covers the whole surface in a single tone, with no painted decoration, it is called full coverage: that is how the monochrome lines are made.
- Cristallina, clear glaze. A transparent, bright glaze laid over the decoration. It protects it and gives it depth, because the decoration is seen through the glass rather than sitting on top of it. It is the reason the colours do not fade with light.
- Madreperla, mother of pearl. A pearlescent finish that reflects light in a shifting way. It is not a fixed colour: it changes tone depending on where the viewer stands and what light is in the room.
- Antichizzato, antiqued. A treatment that darkens the hollows and leaves the raised parts pale, so the piece looks marked by time. It is a declared aesthetic choice, not real wear and not an indication of age.
- Lustro, lustre. A metallic glaze that gives iridescent reflections, towards copper, wisteria, pearl. It needs a firing of its own and cannot be obtained together with the rest.
- Oro zecchino, pure gold. Real gold applied with a brush to the relief and fixed in the kiln. It is not gold coloured paint and it does not behave like one: it stands up to years, it does not stand up to anything abrasive.
- Terzo fuoco, third firing. The final firing, at a lower temperature than the ones before, which fixes gold and lustre. It is called that because it comes after the first and the second. It is the step that raises the cost of a piece, and it explains why two heads identical in shape can carry very different prices.
The decoration: what you see looking at the piece
- Ornato. The baroque repertoire of Caltagirone: scrolls, leaves and volutes painted freehand with a brush, historically in blue and orange.
- Copricapo, headdress. Everything the figure carries on its head: a pointed crown, a draped turban, a basket of fruit or flowers. It is the element that tells one line from another more than any other detail.
- Perline, beads. Small ceramic spheres applied by hand along the headdress or the neckline, usually red or blue. You can count them one by one, and each is attached individually.
- Con espressione, with expression. The wording we use for pieces where the features are modelled and painted one at a time: eyebrows, gaze, lips. Two examples of the same size do not have the same face, and that is not a mistake.
Common questions
Why do the listings say "one of a kind" if the model is the same?
Because the starting shape is shared, but nothing that comes after it is. The features are refined by hand, the applied parts are positioned by eye, the ornato is painted freehand. Two pieces from the same line resemble each other the way two siblings do.
What is the difference between smalto and cristallina?
Smalto carries the colour and covers. Cristallina is transparent and protects what is underneath. On a decorated piece they work together: first the base glaze, then the decoration, then the clear glaze that seals everything.
Does "antichizzato" mean the piece is antique?
No, and we want to be clear about it. It is a finish made today that imitates the look of time passed. It says nothing about the age of the object.
Does the gold wear away?
Not on its own. It wears if you rub it with something rough or use an aggressive product on it. With a dry cloth and a little care it lasts as long as the piece.
Where can I see all these processes together?
In the line that concentrates them: third firing, pure gold, lustres and mother of pearl all sit on Madreperla Oro e Lustri.
If after this glossary you want to see the words applied to the pieces, that is the place to go: Madreperla Oro e Lustri is the line where nearly every term on this page appears on the same object.
