Royal ceramics

royal ceramic,Appropriate refined clay is formed to the desired shape. After drying it is placed in a kiln or atop combustible material in a pit, and then fired. The typical firing temperature is around 1,000 °C, though it may be as low as 550 °C. The iron content, reacting with oxygen during firing, gives the fired body a reddish color, though the overall color varies widely across shades of yellow, orange, red, “terracotta”, pink, grey. Fired terracotta is not watertight, but surface-burnishing the body before firing can decrease its porousness and a layer of glaze can make it watertight. It is suitable for use below ground to carry pressurized water, for garden pots or building decoration in many environments, and for oil containers. Terracotta, if uncracked, will ring if lightly struck. Some types of terracotta are created using recycled terracotta. Painted terracotta is typically first covered with a thin coat of gesso, then painted. It has been very widely used but the paint is only suitable for indoor positions and is much less durable than fired colors in or under a ceramic glaze. Terracotta sculpture was very rarely left in its “raw” fired state in the West until the 18th century.
