Stabilizing bars, often referred to in stained glass conservation as “rebar”,  are used in stained glass as a way to reinforce the stability of the panels. The rebars we are using for St. Vincent de Paul are flat steel bars. The original bars varied in size from 1/8″ to 1/2″ wide and 1/8″ thick. Rebars are […]

A majority of the panels we are dismantling in this phase have a high number of breaks. Their condition is not surprising considering they are from the south wall of the church. The south wall is subject to the most extreme weather conditions, which can result in a lot of breaks in the glass. While […]

Here is an update on the small, devil piece. It is about 20 feet up from the balcony floor and close to 40 from the ground. At approximately 5″ wide and 6″ high; one could opt to cover the pieces with thick, repair leads and hope no one would notice. But this assumption, applied to the window overall, would […]

We are well on our way into our newest phase of St. Vincent de Paul. Our current project is restoring three large lancet windows (45-47)  and one large tracery  (48) on the south side of the church. This small devil is in the studio as part of the current treatment campaign. We have yet to dismantle this panel […]

view of the south side of the church The beginning of 2015 started off with a large project at the south side of St Vincent de Paul. It’s really exciting because this is the “window” we had originally been contacted to assess 4 years ago when members of the church noticed water damage along the sill. Since the damage was […]

There are a variety of terms we use to construct a window, but the most common are glazing or leading. We call it leading because it is the process of working lead around the loose pieces of glass in order to recreate the original panel. We start with 6 feet long strips of lead called “came”. […]

The pieces of glass pictured above are from St. Vincent De Paul, in San Francisco. The fillets (sometimes called “sacrificial boarders”) have proven to be quite fragile. In this window they are cobalt blue; other windows from the same church have red glass. Historically, fillets are used as an interface between the window and the framework – […]

Dismantling a panel takes a lot of time. It’s part of the stained glass conservation process that people don’t see, but is one of the most labor intensive steps towards restoring a window. Before a panel can be dismantled, we make a rubbing of the window. The rubbing allows us to mark the lines of the lead as […]

We’ve assessed the 18 panels in the studio and have made some interesting discoveries. For one, some of the panels were only soldered on one side, and the interior side at that. We often encounter older windows that have missed joints here and there, but never an entire side. In the photo below, you can […]

Window 35, the Crucifixion,  is the first of the large, arched  “C” windows at St. Vincent de Paul on which we have worked. 18 panels in total, it’s about 20 feet tall by 6 feet wide, with the base starting about 30 feet off the ground. On Site Documentation Documentation is a top priority for […]
