Whilst masons do their work on the East wall, the window is

deconstructed. Each piece is filed and any broken panes need to

be re-made. The originals are used as tracing templates for their

replacements.

Firstly, the line is painted and kiln-fired.

Secondly, the shading is applied, and the glass is fired again.

Shading can be manipulated to give depth to the images and to

distress the basic surface, to emulate the effects of the ravages

of time.

Finally, a yellow stain is applied on the reverse side of the glass,

and fired at a slightly lower temperature than the line and shading.
