Decorative Art Nouveau ceramic tile produced by Wessel, Bonn, Germany, around 1905. The tile features a stylized floral design with radiating petal forms in deep blue and dark purple tones set against a warm olive-green background. The flowing lines and symmetrical composition are characteristic of the Art Nouveau style, emphasizing natural forms and elegant curves. Manufactured using the dust-pressed technique, in which clay powder is compressed under high pressure in a mould, creating crisp and well-defined relief details. Good antique condition with light age-related crazing consistent with its age.
