Holger Walter concerning the realised glass-sculpture:
So far, I have realized my ideas on the one hand with rock as a natural material and on the other hand with works on paper, like gravure printing and ink-drawings.
Rock is a relatively closed material. I open it through radical, yet precise procedures. These "carvings" or "excarvations" enable light to enter the rock where it usually could not be encountered. This way, the heavy rock attains a certain lightless and dynamic appearance despite its natural massive structure.
In my paper works, empty paper spaces are created for example by laying different shades of black on top of each other. These spaces obtain a certain brightness due to the ink areas surrounding them. The "emptiness" of these small paper spaces glows out of the picture.
When I was thinking about how to deal with massive glass and how to use the characteristics of massive glass for my works, I came up with this idea.
The original model for my casted glass is not modeled in clay, as is the case with Ann Wolff's works, but I decided to sculpture.
I chose a rectangular block of sandstone from my studio. Its surface constitutes a diagonal break line. The rough stone with its partly broken edges and with saw markings on its surface underlines the intention as an experiment. On the bottom of the block, so on the surface it stands on, a rectangular space was carved out. The base of the carving is rotated by a few degrees in relation to the block's base.
This way the corners of the carving are located closer to the outside surfaces of the closed block. The rectangular carving measures 16 x 14 cm and is 16 cm deep. For the following glass cast I chose a certain shade of gray from samples. As to the color, it was important to me for it to have a rather unobtrusive and neutral effect. The color should not jump to the eye and not be too ornamental and thus distract from the mere shape.
The immanent property of glass is its translucency. The possibility to have light passing a closed block made me engage in this experiment for my first work with glass.
I was interested in the possibility of making the hidden empty space inside the block visible and palpable with light shining through it. But it should not be a polished display window, meaning no polished glass surface, presenting the inner space. That would have been too obtrusive to me and would have contradicted my idea.
This is why I left the outside surfaces rough and unleveled on purpose. In the cast they appear matte.
The glass block, due to its color and closed appearance, seems to be a gray rock at first glance. Only when observed more closely, does it reveal its gently glimmering inside cave.
