Brown beige square ceramic wall lights in fat lava style. Manufactured by hustadt leuchten keramik, germany in the 1970s. The style of the glaze is called 'fat lava'. Which means the glaze is thick on some parts, like lava. A typical way to finish ceramic in mid-century west-germany, europe. The glaze is in a beige and brown color. We used gold light bulbs (see images), but silver light bulbs are also very stylish. Measurements: height: 8.66" (22 cm) width: 8.66" (22 cm) depth: 4.72" (12 cm) each light requires one e27 light bulb. This piece is attributed to the mentioned designer/maker.
