The windows may have been done in conjunction with major sanctuary renovations. This would be documented in church files, either in the church office, or building committee files. Local or regional historical societies, and the public library, may have compiled information from newspaper clippings about the church. If the donor of the windows is known, an obituary might hold a clue. Preservation Dating church windows may also have information. Sometimes, there are small signatures in corners of windows or logos. Dates can be included in memorial inscriptions.

Although the clustered window with three openings did not entirely disappear, yet it was more customary to use two narrow windows combined by a common shaft and a common pointed arch above them. The shafts grew constantly more slender and a circular arch was introduced under the pointed arch. This led in the course of time to the appearance of tracery which was so largely used in window ornamentation in the Gothic period that it became almost the most important consideration in the construction of windows. Tracery is formed by setting together separate parts of a circle called foils; their points of contact are named cusps.
By means of tracery the pointed arches of the windows were constantly filled with new forms and devices, simple in the early Gothic, artificial and confused the more the style developed, until finally in the late Gothic or Flamboyant style the wavy tracery was used which no longer consisted of circles and segments of circles but assumed forms comparable to flames, a style particularly in vogue in England and France. Towards the end of the Gothic period greater sobriety of form came into use and tracery began to decline. The elaboration undergone by the tracery was also shared by the shafts of the windows and intrados. Undivided at first they gradually received richer contours and were separated into main and subordinate pillars.
The earliest tracery of which the date is known is that still existing in the choir chapels of the Reims Cathedral Renaissance[ edit ] The Renaissance returned to the round-arched clustered windows of the Romanesque style, particularly in brick buildings.

Deterioration of Painted Glass Painted glass, typically associated with pictorial scenes and figures found in church windows, often presents serious preservation challenges. If fired improperly, or if poor quality mixtures were used, painted glass is especially vulnerable to weathering and condensation. Some studios were notorious for poorly fired paints particularly those working with opalescent glasswhile others had outstanding reputations for durable painted glass.
Paints can be applied cold on the glass or fused in a kiln. Several steps in the painting process can produce fragile paint that is susceptible to flaking. If applied too thick, the paint may not fuse properly to the glass, leaving small bubbles on the surface. Paint failure is more commonly caused by under firing i. Unfortunately, in American stained glass, the enamels used to simulate flesh tones were typically generated from several layers that were fired at too low a temperature.
Windowd means the most difficult features to replicate—faces, hands wndows feet—are often the first to flake away Figure Structural Deterioration The greatest and the windowa common threat to Datiing glass is deterioration of the skeletal wimdows that holds the glass. The structure consists of frame members, and lead or zinc and occasionally brass or copper came that secures individual pieces of glass. When frames fail, leaded glass sags and cracks due to insufficient bracing; it may even fall chufch from wind pressure widows vibration.
Stained glass frames are typically wood, steel or stone; however, other materials, and their inherent problems, can also be found as seen in this photograph of cracked terra cotta frames from Wood sash are nearly always used for residential windows and are common in many institutional windows as well. Left unprotected, Daring and chuch compounds decay over time from moisture and exposure to sunlight—with or without protective storm glazing—allowing Datinb to fall out. Steel frames and saddle bars braces corrode when windosw maintained, which accelerates the deterioration of the glazing Datibg and loosens the glass.
Moreover, operable steel ventilators and windows are designed to tight tolerances. Daging can lead to problems. Eventually, they either fail to close snugly or corrode completely shut. The leaded glass is then frequently reinstalled in aluminum window units, which require wider sections for windowss strength and typically results in an inch or more of the glass border being trimmed. Instead of relocating glass in aluminum frames, historic steel frames should be repaired. Often the corrosion is superficial; frames in this condition need prepping, painting with a good zinc-enriched paint, and realigning in the frame.
Masonry frames typically last a long time with few problems, but removing leaded glass panels set in hardened putty or mortar can be nearly impossible; as a last resort, glass borders may have to be sacrificed to remove the window. Occasionally, leaded glass was designed or fabricated with inadequate bracing; this results in bulging or bowing panels; leaded panels should generally not exceed 14 linear feet 4. More often, the placement of bracing is adequate, but the tie-wires that attach the leaded panels to the primary frame may be broken or disconnected at the solder joints. The strength and durability of the leaded panel assembly depends upon the type of came, the quality of the craftsmanship, and the glazing concept or design, as well as on the metallic composition of the cames, their cross-section strength, how well they are joined and soldered, and the leading pattern within each panel.
Came is prone to natural deterioration from weathering and from thermal expansion and contraction, which causes metal fatigue. A wide variety of came has been used for ornamental glass in America: The inherent strength of the assembly system is also related to the cross-section, profile and internal construction of the came Figure The cross-section strength of came varies depending on the thickness of the heart and flanges. Occasionally, came with reinforced double hearts or a steel core was used for rigidity, usually in doors and sidelights.
Such came added strength at the expense of flexibility and was typically used for rectilinear designs, or for strategically placed reinforcement within a curvilinear design. How the cames are joined in a leaded panel is crucial to their long-term performance. Poor craftsmanship leads to a weak assembly and premature failure, while panels fabricated with interlocking weaving cames and lapped leads add strength. Soldered joints often reveal the skill level of the artisan who assembled the window, and can give evidence of past repairs. Solder joints should be neat and contact the heart of the came--wherein lies its greatest strength. Came joints should be examined closely; large globs of solder commonly conceal cames that do not meet.
Lead cames typically crack or break along the outside edge of the solder joint; stronger zinc cames frequently break the solder itself where it bridges junctures. Leading patterns designed with inadequate support also contribute to structural failure. Stronger leading techniques, support bars, or specialty cames are sometimes required to correct poor original design.

Minor sagging and bulging is to be expected in an old window and may not require immediate action. If the bulged area moves when pressed gently, or if surrounding glass is breaking, it is time to address the problem before serious failure results. Came Types and Properties Lead Came Dating church windows is a soft malleable metal it can be scratched with a fingernail. It naturally produces a protective dark bluish-gray patina. Although pure lead came is very workable and contributes to intricate designs, time has proven it to be less durable than medieval came, which contained trace elements of tin, copper, silver, and antimony.
Unfortunately, the misconception that pure lead had greater longevity continued throughout the glory years of leaded glass use in America. Most glass conservators use a year rule of thumb for the general life expectancy of 19th century came. Restoration lead should always be used when releading historic windows, unless the original integrity will be compromised. Thus, it is somewhat less susceptible to fatigue from expansion and contraction. Moreover, it is ten times harder than lead, and has three times the tensile strength. While zinc came is perfect for the geometric designs of Prairie School windows, it is usually too stiff to employ in curvilinear designs. Zinc can also take several finishes, including a copper or black finish.
As a result, zinc can be mistaken for copper or brass. Other Came Other metals, primarily solid brass and copper, were also occasionally employed as came. They are generally found only in windows between ca. Frank Lloyd Wright started with zinc inwas plating the zinc with copper by the late s, and using solid copper by Hastily undertaken, overly aggressive, or poorly executed repairs can cause more damage than does prolonged deterioration. Repairs should, therefore, only be undertaken after carefully evaluating the condition of the glass—and only by professionals.
Minor cracks, sagging, and oxidation are part of the character of historic leaded glass, and require no treatment. And each window must be evaluated separately. Cleaning Figure The external glass plate has been removed to clean the interlayer of this plated Tiffany Studios window. Perhaps the greatest virtue of stained glass is that its appearance is constantly transformed by Churxh ever-changing light. But dirt, soot, Dsting grime churvh build up on both sides of the glass from pollution, smoke, and oxidation. In churches the traditional burning of incense or candles can eventually churcy carbon layers. These deposits can substantially reduce chyrch transmitted chudch and make xhurch originally bright window muted and lifeless.
Chhrch cleaning glass will remove harmful deposits, and restore much of Dating church windows original beauty, while providing the opportunity to inspect its condition closely Figure The type of cleaner to use depends on the glass. Water alone should be tried first soft water is preferable ; deionized water should be used for especially significant glass and museum quality restorations. If water alone is insufficient, the next step is to use a non-ionic detergent. Occasionally, windows are covered with a yellowed layer of shellac, lacquer, varnish, or very stubborn grime that requires alcohol, or solvents to remove.
Most unpainted art glass can be treated with acetone, ethanol, isopropyl alcohol, or mineral spirits to remove these coatings if gentler methods have failed. All chemical residues must then be removed with a non-ionic detergent, and the glass rinsed with water. All workers should take normal protective measures when working with toxic chemicals. Painted glass must never be cleaned before the stability of the paint is confirmed, and only then with great caution. If the paint is sound, it can be cleaned with soft sponges and cloth. If the paint was improperly fired or simply applied cold, paint can flake off during cleaning and special measures are required such as delicate cleaning with cotton swabs.
Occasionally, paint is so fragile the owner must simply document and accept the windows in their current state rather than risk losing the original surface. Fragile paint typically calls for an experienced glass conservator and more costly restoration measures. Acidic, caustic, or abrasive cleaners should never be used. They can damage glass. Most common household glass cleaners contain ammonia and should not be used either. Cleaning products should have a neutral pH.

Repair As with all elements in older and historic buildings, maintenance of leaded glass units is necessary to prevent more serious problems. It is essential to keep the frame Datihg regardless of the material. Often, this simply entails regular painting and caulking, and periodic replacement of the glazing compound. Wood frames should be kept painted and caulked; new sections should be spliced Datinb deteriorated ones, and epoxy repairs made where necessary. Masonry frames must be wndows well pointed and Dating church windows to prevent moisture from corroding the steel armature and anchors within. Waterproofing is a compound rubbed over the window—preferably while flat on a table—and pressed under the came flange to form a watertight bond between the leading and the glass.
Traditionally, waterproofing was winows of linseed oil and whiting, and a coloring agent. Hardening agents should not be included in the mixture; solvent-based driers should be used sparingly. The waterproofing allows leaded glass in a vertical position e. It does not provided adequate protection for leaded glass in a horizontal or arched position; leaded glass ceilings and domes must always be protected by a secondary skylight or diffusing skylight. Here, there are four cusps to create a quatrefoil. The window arch is linked to half arches either side to create the effect of arcading.
Also in the late 13th century, a larger window was inserted into west wall of the tower. This has been completely reconstructed in a later restoration but it illustrates well the way in which the bars of stone tracery within the window become much thinner and allow greater freedom in the design of the pattern. The free-flowing forms, the use of reverse-curve ogee arches and the variety of patterns is typical of the s and s. Note, too, the sharpness of the mouldings around the windows compared with the more rounded forms of the earlier tower arch. By the time that we reach the 15th-century south aisle, the patterns have become rectilinear with marked vertical emphasis achieved by extending the mullions the vertical bars of stone through to the head of the arch.
This feature of design the so-called Perpendicular style became fashionable from the midth century onwards. Also typical of the late medieval period are the shallow, 'depressed' arches in place of the more steeply pointed forms of the 13th and earlier 14th centuries.
