A special type of Kangxi period porcelain bowls were only bisque fired and then decorated with a colored or uncolored low fired porcelain glaze, sometimes with a incised floral patterns and then decorated with white, yellow and green on a purple, brown green, yellow and white grounds. These are generally known as 'brinjal' (aubergine/eggplant) owls' after their dominating color.
A special version of this kind of bowls are called 'egg and spinach' since they are decorated with yellow and green splotches in a regula pattern.
This decoration specifically imitates the Tang dynasty 'three colored' sancai lead glaze decoration common on funeral wares of the time. 'Egg and spinach' occurs in various degrees, from late Ming and stylistically develops into the famille verte, famille noire and famille jaune decorations typically of the Kangxi period, as well as continues on its own, into modern time.
