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 […]

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 […]

Last year, Nzilani was approached by the Swedenborgian Church in San Francisco to work on a stained glass window of St. Christopher by Bruce this Porter. Our discoveries of Porter’s work proved fascinating and challenging with the condition of the window. Church parishioner and photographer Doug Stinson worked closely with us to document our conservation process of […]

At Nzilani, we’ve developed a protocol for windows in architectural settings in which surveys are imperative before embarking on any conservation. Multi-phase treatments are considered components of a whole, rather than conceived and executed in isolation (or worse, as an afterthought); even if separated by years. Viewing the project holistically is key to its sustainability.” […]

Broadly placed in two categories: museum objects, or functioning components of historic buildings; the criteria of conserving these works of art are project-specific. The majority of our projects at Nzilani take place in historic buildings. Our first priority for the windows is to stabilize them in order to survive and be appreciated by future generations. But beyond […]

Here is how one perceives a “typical” leaded window to look. Yet this is only the base layer of a Tiffany panel we have in the studio. We had to remove over 99% of the platting from panels 2 &3 from Tiffany’s “Garden Staircase” in order to clean and stabilize all of the different elements underneath. […]

On any stained glass conservation project, we are are constantly weighing the validity of conserving a piece against the necessity of making it function as a key component in a building’s architecture. One of these decisions includes deciding when to keep the original border lead and when to replace it. The window we are currently […]
