Three-phase firing (or three-step firing) or iron reduction technique is a firing technique used in ancient Greek pottery production, specifically for painted vases. Already vessels from the Bronze Age feature the colouring typical of the technique, with yellow, orange or red clay and brown or red decoration.
Iron is the most common material found in clay, and can add red, grey, or buff coloring to the object. [5] Pottery can be coarse wares, which are undecorated or only minimally decorated utilitarian vessels, or fine wares, which are decorated, finely potted, and used for a variety of purposes, including ceremonial use.
Pieces can be grey, red, or white, painted with iron oxide or decorated with glaze. Shino glaze ( 志野釉 , Shino uwagusuri ) is a generic term for a family of pottery glazes . They tend to range in color from milky white to orange, sometimes with charcoal grey spotting, known as "carbon trap" which is the trapping of carbon in the glaze ...
Underglaze transfers are a technique that involves screenprinting or free handing a pattern onto a transfer paper (often rice paper or newspaper) which is then placed, dampened, and burnished onto the surface of a leather-hard piece of clay (similar to how a lick-and-stick tattoo might be applied).

A series of analytical studies have shown that the striking black gloss with a metallic sheen, so characteristic of Greek pottery, emerged from the colloidal fraction of an illitic clay with very low calcium oxide content. This clay slip was rich in iron oxides and hydroxides, differentiating from that used for the body of the vase in terms of ...
Clay was all around and the main material; often modelled figures were painted with black decoration. Carefully crafted and dyed pots, especially jugs and bowls, were traded. As dyes, iron oxide containing clays were diluted in different degrees or various minerals were mixed to produce different colours.
The iron in the clay absorbs oxygen and becomes the red or red-brown iron(III) oxide. The resulting pottery has a red-brown colour. [25] The simplest and earliest firing method is the open fire. The vessel to be fired is covered and filled with flammable material. It is placed on a flat piece of ground, surrounded by a low wall, or put in a pit.
Potters began to draw polychrome paintings on the white opaque surface with metallic oxides such as cobalt oxide and to produce lustreware. The off-white fired body of Delftware and English Majolica was made to appear white, and hence mimic the appearance of Chinese porcelain, by the application of a glaze opacified and coloured white by the ...
