Computer aided glass staining techniques

Teun Hocks, famous Dutch painter, obtained by competition the mission to produce 3 stained glass windows for the 13 th century “Grote Kerk”at Dordrecht. Dordrecht is an old port, situated at the Merwede, a big river that pours in the Rhine that flows through Holland, Germany, France and Switserland. On these waterways the boats sailed to these countries.

In every medieval city the economical traffic was managed by the guilds.

Teun's look on the guilds is depicted in these windows, there are accessories that, direct or indirect, have a relation with the crafts. Holland developed in the glassworld a unique style of its own. Great painters like Rembrandt and Frans Hals left their influence. Bronckhorst and the Brothers Crabeth designed the windows, that had originally religious subjects, in a more sophisticated way. This tradition is maintained by Teun Hocks. The realism, feature of the Dutch School, is reinforced by the combination of photographic reproduction and painting.

The technical knowledge, necessary to produce the work of Teun has been provided and executed by Stef Hagemeier. As a glazier he restored more than 300 churches

To build with glass paint a three-dimensional image is a technique that has fascinated glaziers for centuries. The photographic image was translated via screen printing in a glaze technique where layer after layer gave depth to the image. Transparant enamel paints gave the final colour. The printed and painted glass sheets were cut with the waterjet to the lead grid. It was leaded and positioned in traditional way.
