This is a Art Nouveau ceramic tile, from Wessel’s Wandplattenfabrik in Bonn, Germany, dating to the height of the Jugendstil period around the turn of the 20th century. The tile is rendered in a stunning deep teal or rich cobalt blue glaze that showcases a luxurious, almost liquid sheen, appearing to be in beautiful, antique condition. The surface features a dense, symmetrical design executed in relief, a technique that allows the brilliant glaze to pool in the recesses while clinging smoothly to the sharply defined ridges. The central motif is a highly stylized, abstract depiction of an ascending floral or foliate form, characterized by powerful, sweeping lines that suggest growth and vitality.
