A vintage 1970s West German ceramic vase by Carstens, form no. 5095.
A beautiful use of the lava glaze here, enhancing the form rather than obscuring it, but giving it a simultaneously organic and alien quality and a sense of timelessness or antiquity - or both.
A vase with a strong textural appeal, standing at 25 cm (10") high, this will imbue any decor with a striking personality.
I have not found any flaws aside from the chip on the base which you can see in the base shot.
