  Last week, we completed installation of temporary glass in the 7 roses of the New Testament Window (#41) at Grace Cathedral.  This week we focus on the 5 tall, narrow spires called lancets below the roses. Each lancet is dedicated to an individual saint (Peter, James… John & Thomas), with Jesus in the center. Unlike […]

From the ground, a visitor to San Francisco’s Grace Cathedral will see beautiful, multi-colored stained glass windows. However, once those windows are removed from their stone niches, the crew at Nzilani see the windows in a much different light, literally.  Take for example the following panel, (the bottom of St. Thomas’s feet, of the New Testament):   […]

Grace Cathedral Extensively Restoring Stained Glass Windows We are so excited to announce that our work at Grace Cathedral has made it into the news! For a sneak peak of what Nzilani will be working on until March 2016, watch the video above, or click the link. We hope to do another in progress news segment […]

Nzilani continues to be excited with our new project at Grace Cathedral. We are overjoyed with our spread in the San Francisco Chronicle this week, which shows a sneak peak on site and in the studio.

About half a year ago; we were contacted by Grace Cathedral in San Francisco. They had received a gift from an anonymous donor who had earmarked the funds to go towards the preservation of the building, particularly the windows. We recommended surveying all 66 art glass windows before we embarked on any work.There are two main […]

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 […]

The treatment cycle happens in phases, but first we survey the windows. Once we have a complete survey of the entire building we select in what order we will conserve the windows. With large scale projects, we often don’t take all of the panels out at once; so we organize them into a conservation timeline based […]

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 […]
