The colored glass shield in the coat of arms shows the name "Dürer" with a pair of opened doors. The crowning adorned helmet with slashed mantling in the colors of the coat of arms creates a full set of
armorial bearings.
Dürer produced a woodcut with this coat of arms in 1523, but it should be understood as a trademark, not a symbol of class status.
This type of panel comprising a stained glass picture is known as a "Kabinettscheibe" in German. The carefully cut individual pieces of glass are joined together with strips of lead. The image is completed with details and structures painted on with a type of sepia enamel known, even in English, as "schwarzlot."
The German term "Kabinettscheibe" gets its name from the use of such glass inserts for non-church settings, like rooms in middle-class homes, halls for family gatherings, writing rooms, cabinets of curiosities, or meeting rooms. But such expensive, one-of-a-kind images might also be integrated into plain glass windows to adorn a private chapel or its choir.
The Kabinettscheibe business boomed in Dürer's Nuremberg. This particular example was not made until 1880, and is the work of the stained glass artist Christoph Philipp Böhmländer (1809–1893), who lived in the Dürer house himself for a time.
