Ceramic Frit General Comments;
CERAMIC FRIT SPANDREL:
Minimum Size: 12” x 24” (unless special circumstances arranged)
Colors: Wide Range of Standard and Custom Colors available. Call for information.
All of R.G. Hull & Associates Inc. spandrel glass is designed to be glazed against a uniform, opaque background and is not recommended for use in transoms, partitions or other
areas where a dark background is not available. All glass substrates for spandrel must be heat-treated. Spandrel is heat strengthened or tempered on request of customer.
Inspection guidelines/quality per ASTM C 1048. Color and reflectance may vary slightly when viewed against a uniform, opaque background and is considered acceptable. Pinholes
and scratches viewed in reflectance are considered acceptable.
Custom Color Ceramic Frit; Custom colors available and subject to approved samples. Full size mock-ups are recommended. All custom projects must be approved by the
architect or building owner after viewing full size mock-up.
White and Pastel Colored Ceramic Frit
Variations in perceived color may occur with any ceramic frit color. These variations will be more apparent with white or light colors rather than darker colors because of
unavoidable light transmission. Furthermore, due to inherent variations in ceramic frit thickness, light colors are more readily influenced by the colors of materials installed behind
the glass. If, for instance, a white ceramic frit is specified, the area behind the glass should be a uniform light color versus a dark uniform color.
White and pastel colored ceramic frit may require a double pass with additional charges and must be approved by the architect or building owner after viewing a full size mock up.
It is important that this mock-up include materials representative of those that will actually be installed behind the spandrel panel.
While R.G. Hull & Associates Inc. and its facilities will take every precaution to control color uniformity, R.G. Hull & Associates Inc. takes no responsibility for variations in color
thickness, which are within our quality standards.
It is important to note that small samples such as 4x4, 12x12 or similar are only representative of proposed products. Since lighting, natural and manmade, along with framing
and other installation configurations can affect the appearance of glass with or without surface treatments. And different sizes, especially small ones refract, reflect and
absorb light differently. The best recommended means of determining final project material and glass performance is from the use of a full size mock up on any project.
Color and Color Tolerances in the Architectural Glass Industry
Because of natural changes in raw materials, every industry requires a quantitative system of measurement to insure that its products will stay consistent from one batch to
another. Many techniques to specifically measure color have been developed. Some are in forms of comparison to set color chips and others use numerical data found from
electronic equipment. In 1931, the CIE (Commission Internationale de l'Eclairage) created a method that allowed color measurement based on the perception of the human eye.
Most modern color systems have adopted this data model.
The intensity of specific wavelengths of light influences the perceived color. Light travels to the human eye by two means, the light that reflects off an object and the light that
transmits through an object. These are perceived as the reflected and transmitted colors. Both of these types of light affect the color of glass. When a manufactured good must
meet a particular color specification, the color system must compare data from the product to a static production standard. The variance between the two colors will determine
whether the product is acceptable or if modification to its formula is necessary. The difference in color is referred to as the delta E. A determined value of Delta E is used as a
guideline for mixing and re-matching colors.
When fabricating decorative glass, there are two ways in which the color is hindered. The first is the pigments present in the coatings applied to the surface of the glass. Pigments
are typically mined materials and have inconsistent levels of impurities. These contaminates, even at very low levels, can change the color of a product enough to make it
unacceptable. The result is that the producer has to compensate by adjusting the amounts or the colors of pigments used.
The second obstacle is the color of the glass itself. The oxides used in manufacturing glass have the same traits as pigments; however, the colors are produced by a chemical
reaction. During the manufacture of float glass, the hue is tested continually to ensure that it meets a specific range of color. If the contrast is too high, slight adjustments to the
formula will shift it back to the center of the spectrum. The color will be acceptable but is rarely identical. The final fabricator is challenged by the compound effects provided by
minute changes in both the glass substrate and the coatings applied.
A common example of complications for a decorative glass manufacturer is the case when a paint color is matched too far in advance. Initially, the customer supplies a color chip
to match. The producer will provide a sample that, when painted on the back surface of the glass, is as close as possible to the customer’s request. When a job performs within a
few months of sample approval, there is little chance that the company has replaced the materials used in making the sample. However, the longer time that elapses, the more
likely that the materials will be of a different hue which necessitates an adjustment to the color formula to ensure the new material on the new glass is comparable to the original
mock up. This scenario is the norm for most industrial fabricators.
Every industry must alter their colors to keep within a dictated range. The paint supplier and the glass supplier go through the same process, as mentioned earlier. Unfortunately,
some adjustments can make certain colors impossible to match a second time. For example, an off-white color matched on a piece of clear glass will be problematic because of
the glass hue. From one crate to the next the glass color can shift to the green side at a delta E of 0.05. This very small change is tolerable by industry standards and undetectable
to the human eye. However, when paint is applied to its surface the color will appear grey. Any adjustment to the formula will make the color darker or push the Delta E too far
causing an unsuccessful match. To avoid delays resulting from these deviations, the recommendation for all jobs requiring custom colors is a full size mock-up immediately prior to
the job release.

How it works......
Slip resistant glass increases the static frictional force required to move an object across its surface. The texture is fused onto the surface of the glass and uses no foreign materials
that wear or separate from the glass under constant use, unlike carbides or Aluminum oxide. In both wet and dry laboratory tests, the product has proven to be far superior to
etched glass.
Untreated Glass
Plain glass has a flat surface with no ‘bite’; all static and kinetic friction rely totally on the molecular bond of the glass and the persons shoes.
Etched Glass
Etched Glass has more tooth than flat glass; however the top surface is still relatively flat and the angle of the indentation is small.
Slip Resistant Glass
Slip resistant glass has a texture that protrudes outwards as opposed to shallow chips being removed from the glass. This makes the surface far more rough and increases the
contact angle between the glass and traffic. The tips of the texture are less prone to abrasion and wear.
Glass Cleaning Instructions;
Exterior: Regular cleaning is an important part of building maintenance when glass is used on the exterior of a building. Pollutants in the air and water and run off from concrete
or mortar during construction will leave deposits on the glass. These deposits, if left to sit and not cleaned off during routine maintenance, will corrode the glass and permanently
etch the surface.
To wash glass on the exterior of a building, first rinse it off with fresh clean water to remove any loose dirt or other particles that may scratch the glass. After the glass is
thoroughly soaked, using a mild, abrasive free detergent and a soft brush or other non-abrasive applicator to wipe down the glass. Dry the glass with a squeegee; any residue on
the glass or surrounding gaskets, frame or sealants must be wiped dry with a cloth.
Interior:
Cleaning glass in an interior application requires some delicacy, especially if the surface is etched. The glass should be cleaned with a mild, non-alkaline detergent that contains no
abrasives or polishing agents to prevent scratches or residue left on the glass which may cause patchiness on the etched surface. Abrasive or caustic cleaners are not to be used in
any application. Wipe the glass until dry using a soft cloth or paper towel removing any streaks that may have formed; liquids left on the glass may cause staining. If any
contaminants remain on the glass, a solution of 50/50 of water and isopropyl alcohol can be used to remove it. This works well with sticky or gluey materials. Use light to
moderate pressure as excessive pressure or hard scrubbing motions may damage the glass surface.

Proper Procedures for Cleaning Architectural Glass Products
Architectural glass products play a major role in the comfort of living and working environment of today’s homes and commercial office spaces. By providing natural daylight, views of the surroundings, thermal comfort and design aesthetics, glass
usage and condition often affect our selection of where we live, work, shop, play and seek education.
Architectural glass products must by properly cleaned during construction activities and as a part of a routine maintenance in order to maintain visual and aesthetic clarity. Since glass products can be permanently damaged if improperly cleaned, glass
producers and fabricators recommend strict compliance with the following procedures for properly cleaning glass surfaced.
As dirt and residue appear, interior and exterior glass surfaces should be thoroughly cleaned. Concrete or mortar slurry which runs down (or is splashed on) glass can be especially damaging and should be washed off as soon as possible. Before
proceeding with cleaning, determine whether the glass is clear, tinted or reflective. Surface damage is more noticeable on reflective glass as compared with the other glass products. If the reflective surface is exposed, either on the exterior or interior,
special care must be taken when cleaning, as scratches to the reflective glass surface can result in coating removal and a visible change in light transmittance. Cleaning tinted and reflective glass surfaces in direct sunlight should be avoided, as the
surface temperature may be excessively hot for optimum cleaning. Cleaning should begin at the top of the building and continue to the lower levels to reduce the risk of leaving residue and cleaning solutions on glass at the lower levels. Cleaning
procedures should also ensure that the wind is not blowing the cleaning solution and residue onto already cleaned glass.
Cleaning during construction activities should begin with soaking the glass surfaces with clean water and soap solutions to loosen dirt or debris. Using a mild, non-abrasive commercial window washing solution, uniformly apply the solution to the glass
surfaces with a brush, strip washer or other nonabrasive applicator. Immediately following the application of the cleaning solution, a squeegee should be used to remove all of the cleaning solution form the glass surface. Care should be taken to
ensure that no metal parts of the cleaning equipment touch the glass surface and that no abrasive particles are trapped between the glass and the cleaning materials. All water and cleaning solution residue should be dried for window gaskets,
sealants and frames to avoid the potential for deterioration of these materials as the result of the cleaning process.
It is strongly recommended that window washers clean a small area or one window, then stop and examine the surface for any damage to the glass and/or reflective coating. The ability to detect certain surface damage, i.e. light scratches, may vary
greatly with the lighting conditions. Direct sunlight is needed to properly evaluate a glass surface for damage. Scratches that are not easily seen with a dark or gray sky may be very noticeable when the sun is at a certain angle in the sky or when the
sun is low in the sky.
The glass industry takes extreme care to avoid glass scratches by protecting all glass surfaces during glass manufacturing and fabrication, as well as during all shipping and handling required to deliver the glass to the end user. A large percentage of
damaged glass results from non-glass trades working near glass. This will include painters, sparklers, ironworkers, landscapers, carpenters and others who are part of the construction process. They may inadvertently lean tools against the glass, splash
materials onto the glass and/or clean the glass incorrectly, any of which can permanently damage glass.
One of the common mistakes made by non-glass trade’s people, including glass cleaning contractors, is their use of razor blades or other scrappers on a large portion of the glass surface. Using 2,3,4,5 inch and larger blades to scrape a window clean
carries a large probability for causing irreparable damage to glass.
The entire industry of glass manufacturers, fabricators, distributors, and installers neither condones nor recommends widespread scraping of glass surfaces with metal blades or knifes. Such scraping will often permanently damage or scratch the glass
surfaces. When paint or other construction materials cannot be removed with normal cleaning procedures a new 1” razor blade may need to be used only on non-coated glass surfaces. The razor blade should be used on small spots only. Scraping
should be done in one direction only. Never scrape in a back and forth motion as this could trap particles under the blade that could scratch the glass. This practice may cause hairline concentrated scratches, which are not normally visible when
looking though the glass, but may be visible under certain lighting conditions.
Members of the Glass Association of North America (GANA) publish information relating to jobsite protection and cleaning of architectural glass products. In order to ensure long-term performance of the glass in a building, GANA encourages glazing
contractors, general contractors, building management and owners to be aware of conditions that can damage glass and to follow the handling and cleaning guidelines provided by their glass producer and fabricator.

GLASS STAINING TECH TALK
This Tech Talk provides you with important information on the causes of glass staining, and how to prevent it from occurring during construction and storage.
DURING CONSTRUCTION
Overall, flat glass for commercial buildings is uniquely resistant to chemical attacks and other types of deterioration. However, glass staining can occur from a reaction to acids used during new concrete
cleaning, masonry runoff and prolonged water contact during storage and shipment.
Glass staining implies a chemical change or degradation to the glass surface. Glass is inert to most acids, as well as other chemicals. Only phosphoric and hydrofluoric acids are harmful to glass. In concentrated
form, these two chemicals will rapidly etch a glass surface. During building construction, hydrofluoric acid is often used to clean new concrete. This solution can accidentally splash onto the glass, seriously
staining it in just one hour, resulting in costly glass replacement.
Unlike acids, alkaline cleaning materials, such as ammonia and tri-sodium phosphate, will attack glass surfaces. In concentrated form, these solutions can cause serious etching. Diluted, these alkaline solutions
still attack the glass but, more slowly. As a result, glass surfaces should always be thoroughly rinsed after cleaning to avoid staining.
Concentrated liquid cleaners used as a lubricant for gasket glazed installations can also cause glass staining. Even though the glass is rinsed, some of the cleaner can get trapped between the gasket and the
glass. This cleaner eventually seeps out, attacking the glass. As a result, it is important to use lubricants recommended by the gasket manufacturer.
Glass staining after installation can occur from the rain run-off of unsealed concrete panels or mortar joints. This concentrated alkaline solution can cause serious glass etching in a matter of days.
DURING STORAGE AND SHIPMENT
Glass staining during storage or shipment is normally caused by an alkaline attack triggered by the presence of water. Water from a leaky pipe or roof may collect between the glass panes when stored inside a
building if the glass is packed too close together in crates or on racks. If the glass is stored outside, water may collect between the panes from rain, snow or groundwater.
Condensation of water vapor on the glass can also cause glass staining and etching when glass is stored outside or in an unheated warehouse. The condensation is a result of the glass temperature being below
the dew point of the surrounding air. The glass temperature changes more slowly than the air temperature because of its bulk and the temperature lag of the glass.
A crate of glass stored overnight during cool temperatures may be close to the air temperature early in the morning. However, after sunrise the air temperature and moisture vapor content often increases
rapidly, while the glass remains at a much lower temperature for hours. The results are condensation and trapped water, making it difficult for the water to evaporate–sometimes taking up to 24 hours to
evaporate. If the same temperature cycle reoccurs, the glass surface can remain wet for weeks or months. As the water evaporates, the alkaline solution becomes more and more concentrated, eventually
etching the glass surface.
STAGES OF GLASS STAINING
During the first stage of staining, you will see a transparent white film appear on the glass. Under certain lighting conditions for installed glass that has not been washed, the white film covers the entire glass
surface. Visually, it cannot be readily separated from surface contaminations, such as cigarette smoke, atmospheric dust and other materials.
The second stage appears as an iridescent, discoloration or oil film on the glass surface. It is multi-colored with an irregular pattern. It can be seen when daylight or other light sources are viewed in reflection
from the glass surface.
The final stage produces an irregular translucent white discoloration, which can be seen under most lighting conditions. It can also reach the stage where an object cannot be clearly distinguished through the
glass.
BUILDING DESIGNS
By designing a building wall that eliminates or minimizes contact between the glass and run-off from its opaque portions, you can decrease the possibility of alkaline staining. For instance, treat all concrete
and mortar surfaces with silicone or other surface sealers. Or, design drip caps into the wall system to divert water away from the glass.
CONSTRUCTION
During construction, it is virtually impossible to prevent some alkaline materials from washing over the glass. If it occurs, the glass should be washed within a few days. This can increase building costs, but it is
less costly than replacing the stained glass.
One cost-effective method is to protect the glass with clear polyethylene sheets. The sheet should be vented and not touch the glass. The vented holes should be 1 inch (25.4 mm) in diameter and be placed
every 12 inches (304.8 mm) along the top and bottom. This can also be used to protect glass when hydrofluoric acid is used for cleaning concrete.

STORAGE GUIDELINES
If glass is stored in crates, stoce packs or under conditions where it touches or is separated by interleaving materials, ensure that it is kept dry at all times.
Once water is allowed to penetrate between the glass panes, the potential for staining and etching increases. If the interfaces become wet, separate the glass plies to allow them time to dry. Since water vapor
is a gas, it readily penetrates between glass plies that are in contact with each other. To prevent moisture condensation, keep the glass temperature above the dew point of the surrounding air. For glass
stored indoors, maintain a uniform indoor temperature. For glass stored near loading docks, do not expose the glass to cold outdoor air temperatures longer than 15 to 20 minutes.
For glass stored outdoors, try to keep the glass at the outdoor air temperature or warmer. Store the glass crates or stoce packs under cover to protect against rain, snow and direct sunlight and do not obstruct
air movement around the crates. Direct sunlight on crated glass can cause breakage from thermal stresses. For insulating glass, high temperatures from solar heating can cause expansion of the air spaces,
which results in glass breakage or damage to the edge seals. Shaded areas with surfaces heated by the sun are ideal.
Do not wrap stored glass in polyethylene sheets or other impermeable material. Instead, use roofing paper, which does not allow the liquid to penetrate, but allows the passage of water vapor. If construction
delays occur, make arrangements to have the unprotected glass stored off site to prevent staining damage.
TYPES OF CLEANERS
The following list of glass cleaners may be used to clean the glass surface. The list of cleaners begins with the mildest and progresses to the strongest. Once you find a cleaning solution that removes surface
contaminants, stop at that level and do not use a stronger solution.
A. Commercial glass cleaner
B. Isopropyl alcohol (IPA) and water (50-50 mix)
C. Soft Scrub™ cleanser
D. Cerium oxide and water
TYPE A AND B CLEANING PROCEDURES
1. Apply commercial glass cleaner or IPA and water to glass. You can either spray it or use a clean, grit-free cloth or sponge saturated with the cleaning solution. It is recommended to clean an area no more
than 10 to 15 square inches (6452 to 9678 square mm) at a time.
2. Apply light to moderate pressure using a circular motion when wiping the cleaning solution on the glass surface. Three to five passes in the affected area may be required to remove the residue, depending
on the adhesion and severity of the residue.
3. Rinse immediately with clean water and remove any excess water from the glass surface with a squeegee or a clean, lint-free cloth.
4. If residue is still present, repeat steps 1 through 3.
TYPE C AND D CLEANING PROCEDURES
1. Make a paste with either Soft Scrub cleanser or cerium oxide and water.
2. Using a clean, lint-free cloth, wipe the paste onto the glass, using a circular motion and light pressure (two to four pounds). Since Soft Scrub and cerium oxide are abrasive they could scratch the glass if
greater pressure is used. Three to five passes in the affected area may be required to remove the residue, depending on the adhesion and severity of the residue.
3. Rinse immediately with generous amounts of clean water and remove any excess water from the glass surface with a squeegee or a clean, lint-free cloth.
4. If residue is still present, repeat steps 1 through 3.
Only optical-grade cerium oxide should be used. It can be obtained from the following companies:
Sommer and Maca Industries, Inc.
5501 West Ogden Avenue
Chicago, IL 60650
800.323.9200
C.R. Laurence Company, Inc.
2503 East Vernon Avenue
Los Angeles, CA 90058
800.421.6144
IMPORTANT NOTES:
1. These cleaning recommendations are intended for uncoated glass surfaces only. They are for specific projects with severe residue and dirt buildup. These should not be used as standard cleaning
procedures.
2. Do not clean the glass under direct sunlit conditions.
3. Start cleaning the glass at the top of the building, systematically working downward. This reduces the risk of residue and cleaning solution from contacting clean glass at lower levels.
