Wilfried Grootens is a German glass artist, born in Uedem and based in Kleve, whose distinctive sculptural practice brings together glass painting, optical illusion and geometric form. Working with layers of painted float glass, he creates complex three-dimensional compositions that appear to shift, multiply and dissolve as the viewer moves around them.

Wilfried Grootens approaches glass as both a physical material and a space for painting. His sculptures are constructed from individually painted sheets of float glass, which are layered, laminated and polished into precisely defined geometric forms. Within these transparent structures, fine brushstrokes align across successive planes to create images that appear suspended inside the glass.
Perspective is fundamental to the experience of Grootens’ work. Forms that seem clearly defined from one position can multiply through reflection, shift in density or disappear almost entirely when viewed from another. The sculpture therefore resists a single fixed image: its internal composition is continually reconstructed through the movement of the viewer.
This relationship between two-dimensional mark-making and three-dimensional form has its roots in Grootens’ early training as a glass and porcelain painter. Yet his use of painting extends far beyond the surface. By distributing individual marks across multiple transparent layers, he transforms them into volumetric structures, making depth itself an active element of the composition.
The precision of Grootens’ technique is balanced by a strong sense of visual instability. Solid geometric objects contain forms that seem weightless and spatially ambiguous, while reflection and transparency blur the distinction between what is physically present and what is optically produced. The result is a distinctive sculptural language in which painting, glass and perception become inseparable.

Artist Statement
With my glass painting, I explore transparent geometric spaces and the variations of form that emerge within them. Different viewpoints reveal new perspectives on seemingly floating forms constructed from fine linear brushstrokes.
I work primarily with float glass, painting or drawing on individual panes before layering and gluing them together. Through this process, the painted marks combine across multiple planes to create three-dimensional forms that appear to float within the glass.
As the viewer moves around the object, these internal forms continually change. Depending on the viewing angle, they become more or less visible, are reflected within the polished surfaces and can appear to dissolve almost completely. In this way, a single object reveals different forms, reflections and perspectives according to the position from which it is viewed.
