What colour is Sang de boeuf glaze?
Sang de boeuf glaze is a deep, rich red used on porcelain and ceramics. It stands out for its glassy surface, which can show crackles, bubbles, and streaks, with the colour sometimes fading to white at the top or thickening at the base. The glaze can also show greenish edges and sometimes hints of turquoise, lavender, or purple. Its unpredictable patterns and depth set it apart from other red glazes.
Where does Sang de boeuf glaze come from?
The name sang de boeuf comes from French, meaning "ox blood", and refers to the glaze's deep red colour. It was first developed in Jingdezhen, China, around 1705–1712, as an attempt to recreate the lost 'sacrificial red' glaze of the Ming dynasty. The original sacrificial red was used for imperial ritual vessels and was associated with the altar of the Sun. Later, the glaze became popular in the Qing dynasty and was admired for its historical links and decorative effects.
How is Sang de boeuf glaze made?
This glaze is made by adding copper oxide to the glaze mixture and firing it in a reducing atmosphere, which means the kiln has little or no oxygen. Sometimes, finishing in an oxidising atmosphere was also part of the process. The glaze is usually applied to the outside of closed shapes, often by spraying, with the inside and rim left clear. Achieving the right colour and effects is technically challenging and depends on many sensitive variables.
