A window has no colour of its own.

It has whatever the light gives it. Everything below is the same glass — move the light and see what happens to it. That is the whole argument for doing this work well.

IThe argumentWhy the hour matters

Glass is chosen for the hour it will be seen in.

A studio does not pick colour on a bench under a lamp. It picks it for a north wall in February and a south wall at four in the afternoon, for the depth of a reveal and the height of a sill. Which is why the slider above is not decoration: it is the single variable the craft is organised around.

Drag it. The photographs do not change — only the light does.

IIIYale Repertory TheatreOne window, twice

The same window, before the studio and after it.

Restoration is not cleaning. The panel comes out, the lead is cut away, every piece is documented, matched, replaced where it must be, and the whole thing is releaded, cemented and reglazed. Then it goes back into the opening it came from.
