Six's technique is the modern name for a technique used by Attic black-figure vase painters that involves laying on figures in white or red on a black surface and incising the details so that the black shows through. It was first described by the Dutch scholar Jan Six in 1888,[1] and was given its English name by J. D. Beazley.[2]
Around 530 BCE, the technique began to be used regularly for decorating the whole vase, rather than for details as in previous practice. The effect is similar to red-figure painting. Nikosthenes, Psiax, and the Diosphos Painter were among the early users of the technique. It remained in use until the mid-5th century, when it can be observed on a small number of oenochoe from the Haimon painter workshop.
