Vase

This is painted by Mrs. Jongsma in 1970 for "de Porceleyne Fles" from Delft.

This is a piece from the Delvert collection (also known as "Green Delft").
The Color (Delvert): Unlike standard Delft Blue, you can recognize this series by the characteristic blue-green (turquoise) color. This line was introduced in 1967, based on designs by Herman Sanders.

The production of this series proved to be technically very difficult because the green color was often unstable during firing. Therefore, production was already discontinued in 1976. There was a brief reintroduction in the 1990s, but that also stopped quickly. This makes Delvert pieces rarer than traditional blue.

Although the motifs (such as the stylized peacock tail-like leaves on your vase) are based on classical forms, they have a much more modern look due to the color and the cleaner lines, which is typical of the 1960s and '70s
