How to Select the Right Acid-Etched Glass

While the glass etching process is generally the same, variations in the chemistry and other process parameters will create different glass surfaces with varied visual and performance characteristics

• Light diffusion
• Privacy
• Glare reduction
• Dimensional effect
• Visual appearance
• Integration with surrounding objects
• Light transmission
• Energy efficiency

An etched surface with rugged peeks and deep valleys absorb and diffuses light, rather than transmit or reflect it, resulting in a rich white opaque appearance.  On the other hand, an etched surface with smooth rounded bumps enhances light transmission and creates a more transparent glass, characterized by reduced reflective glare and a soft translucent appearance.

The type of acid-etch surface finish selected will render a different level of opacity and smoothness as well as create varied visual effects.  It will also have an impact on the following performance ratios:

–          Gloss

–          Visible light transmission

–          Visible light reflectance

–          Shading coefficient

–          Solar direct transmission

–          Solar direct reflectance

–          U-Value

Also, bare in mind that the type of glass substrate used will impact on the above-mentioned characteristics. For example, acid-etched glass made out of low-iron glass (e.g. Starphire ultra-clear glass by PPG) will create a translucent satin appearance without the “greening effect” of ordinary clear glass.  Similarly, acid-etched blue glass made out of PPG’s blue Pacifica will create a different visual effect than one made with Pilkington’s Artic Blue.

Consequently, both the acid-etch finish and the glass substrate used will impact on the color appearance, level of opacity and performance ratios of the acid-etched glass.

In order to enhance certain characteristics of the acid-etched glass, you may also consider etching the glass on both sides.  This is a good approach for applications requiring a higher level of opacity or a similar finish and visual effect on both sides of the glass panel (e.g. partitions).

The use of acid-etched glass for exterior applications may also be appropriate.  Because acid-etching is not a coating, its resistance properties in exterior conditions are essentially equivalent to un-etched glass.  However, it is important to point out that an etched surface with rugged peeks and deep valleys could lead to higher maintenance costs because dirt particles may be more difficult to remove.  Therefore, the use of an etched surface with a lighter finish (smooth rounded bumps) is recommended in exterior applications.

As you can see, being specific about the nature of the acid-etched glass product required is very important.  Do not hesitate to share your design and performance intent to our glass professionals to ensure the acid-etched glass product selected meets your goals and objectives.

Bear Glass NJ Acid Etched Glass is becoming trendy in design and construction.  The consistency and durability of the finish can reduce glare and reflection, add privacy, increase light transmission, and provide texture.  It is important to select the right acid-etched glass for an application, and avoid making issues during storage and fabrication.  Although the glass-etching process is generally consistent, variations in chemistry and other parameters create different surfaces with distinct visual and performance characteristics.  Glass is etched with an aqueous solution of hydrofluoric acid, which attacks the silica and roughens the glass surface.  Generally, the more ‘white’ or opaque the finish, the more rough and porous the surface is.  When choosing distinctive and unique types of glass, architects and designers often have specific objectives in mind.  With acid-etched glass, these goals can relate to light diffusion, light transmission, privacy, visual appearance, integration with surrounding objects, and energy efficiency through increased day lighting.  An etched surface with rugged peaks and deep valleys absorbs and diffuses light, rather than transmitting or reflecting it- the result is a rich, white, opaque appearance.  In contrast, an etched surface with smooth, rounded bumps enhances light transmission and creates a more transparent glass, characterized by reduced reflective glare and a soft translucent appearance.

Acid-etched Surface Finish

Acid-etched finished vary by manufacturer.  The type selected for a glass substrate renders a different level of opacity and smoothness and creates varied visual effects.  It also impacts performance ratios such as gloss, visible light transmission (VLT), visible light reflectance, shading coefficient, solar direct transmission, solar direct reflectance, and U-value.  The visual effect of the acid-etch finish on mirror varies depending on the extent of etching performed.  A lighter-etched mirror has more reflection whereas a deeper etch creates a matte finish and more depth in the glass.

Glass Substrate

The substrate also influences the color appearance, level of opacity, and performance ratios of acid-etched glass.  Many falsely believe pieces of ultra-clear glass look the same, irrespective of their origin; similarly, glass with a blue tint from manufacturer ABC is often incorrectly perceived to match the one produced by manufacturer XYZ.  Generally, the glass business markets different shades of glass in ultra-clear, green, blue, or black.  In addition, some glass floaters can make varying shades of one color.  For example, acid-etched products manufactured from low-iron glass have a translucent satin appearance without the ‘greening effect’ of ordinary clear glass.  Similarly, a piece of acid-etched glass made with a dark blue hue from one supplier creates a different visual effect than one made with light blue from the same manufacturer.  Consequently, the shade of the acid-etched glass or mirror likely varies among manufacturers, depending on the substrate used.  It is important to remember the acid-etched finish itself creates a different color appearance, with different tints having varying performance ratios.

Etching on both sides

Etching glass on both sides can enhance its characteristics.  This approach is suitable for applications requiring a higher level of opacity or a similar finish and visual effect on both sides of the glass panel (e.g. partitions).  Most glass is produced by the float process.  The raw materials- mainly silica sand, soda ash, and limestone- are melted in a furnace and then flowed onto a bath of molten tin.  The glass then takes form and gradually cools as it moves from the tin bath to a controlled cooling chamber.  Float glass is best etched on the ‘air’ or ‘atmosphere’ side of the sheet, due to the greater likelihood of impurities and surface imperfections on the ‘tin’ side.  Production of acid-etched mirrors and two-sided etched glass requires etching of the tin side, posing an increased risk of defects in the surface if inappropriately done.   When considering double-sided acid-etched glass or acid-etched mirror, the type of finish specified impacts quality.  The manufacturer of the acid-etched product can recommend the finish (if any) suitable for the application.

Exterior applications

Bear Glass New Jersey Acid Etched Glass may be appropriate for exterior applications, such as insulated glazing (IG) units, skylights, and balustrades.  As acid-etching is not a coating, its resistance properties in outside conditions are essentially equivalent to non-etched glass.  However, it is important to note an etched surface with rugged peaks and deep valleys could lead to higher maintenance costs because dirt particles may be harder to remove.  Therefore, the use on an etched surface with a lighter finish (i.e. smooth, rounded bumps) is recommended in exterior applications.  In these situations, the level and type of maintenance required is similar to that of non-etched glass.

Storage and Fabrication

If proper care is taken during storage and fabrication, acid-etched glass or mirror can be kept clean as easily as non-etched products.  Whether the glass is tempered, laminated, insulated, painted, or even bent, fabricators can preserve the quality of the final product.  However, the general suggestions for keeping acid-etched glass or mirror stain-free during storage and fabrication may not be suitable in all situations.  Fabricators should follow guidelines issued by the manufacturer of a particular product to prevent or fix any marks or stains that occur.

Storage

Proper storage practices can help avoid marking on acid-etched glass and mirror.  Storage spaces must be dry and adequately ventilated.  Sheets should not be stored in areas of high humidity or heat (e.g. places near steam or water pipes).  Spaces exposed to chemical fumes should also be avoided.  All these conditions promote staining.  Conversely, sheets should not be stored outdoors or in unheated areas.

Fabrication

Due to the particular characteristics of more rugged glass surfaces, extra care should be taken during their fabrication to minimize the likelihood of embedding grease or dirt into the surface.  Gloves must always be used when working with sheets.  When handling sheets using equipment with suction cups, the clean and dust-free cups should be applied to the flat, untreated side.  If this is impossible, care should be taken to ensure proper vacuum is achieved (i.e. testing must be done to be certain the cups ‘stick’ to the glass to handle to weight).  When edging glass, these practices should be followed:

1. The edging machine conveyors should be clean and free of grease and buildup of glass grindings or cerium oxide.
2. The conveyor must be regularly opened and the machine interior washed (particularly the brushes) using soapy water.
3. The front and back conveyor pads should be routinely brushed, until all traces of cerium oxide and glass grindings are removed.
4. The front and back conveyors must be synchronized at identical speeds.
5. Only coolants specifically recommended for glass grinding and that adhere closely to the manufacturer’s recommended dilution ration should be used.
6. Manufacturer guidelines for concentration levels must be followed when using cerium oxide, with care taken to never add more than the minimal amount necessary for good polishing.
7. Glass should be washed immediately after polishing.  Washer brushers with .36-mm (0.014-in) diameter nylon bristles offer the best results.  The glass washer should be equipped with one pair of upper and lower brushes for every 0.6m (2ft) per minute of travel- for example, a machine operating as a speed of 1.8m (6ft) per minute should have three pairs of brushes.  (This guideline is only applicable to regular float glass and not to coated products such as low-emissivity [low-e] glass).
8. As an extra precaution, wetting the glass surface immediately before polishing greatly reduces the risk of marking.

Writing the Right Specifications

Architects and designers constantly look to Bear Glass for new ways to use glass in exterior and interior applications.  Writing proper specifications, especially when distinctive and unique types of glass are chosen, is critical to ensure the desired design is achieved.  Acid-etched glass is no exception.  If care is not taken, the glass ordered and installed on the jobsite may be nothing like the product selected based on samples submitted.  To ensure the acid-etched glass products selected are actually used by the general contractor, glass fabricator, and glazier, the following information should be included in the specifications: name of manufacturer, product brand name, glass thickness, substrate (glass or mirror), tint (e.g. clear, ultra-clear, blue, green, black, bronze, grey), type of finish (name), and whether to etch on one or two glass faces.  Warranties and standards are often overlooked when writing specifications.  Inherent in the float glass process are small gaseous inclusions and minor abrasions.  Consequently, occasional, small ‘bubbles’ and hairlines are normal and acceptable under recognized standards; from a normal viewing distance, they are barely noticeable.  To ensure acid-etched products are made from float glass that conforms to industry standards, the manufacturer should be consulted.  In Canada, glass should comply with Canadian General Standards Board (CAN/CSBG) 12.3-M91, Flat, Clear Float Glass (Quality: Glazing).  In the United States, ASTM International C 1036-01, Standard Specification for Flat Glass (Quality: Q3-Stock Sheet) should be followed.  The manufacturer’s product warranty should refer to these standards.  Clearly, it is important to be specific about the nature of the acid-etched glass product required.  Communicating specifications in detail to a glass professional can help ensure the chosen product meets desired goals and objectives.

Resin Stained Glass is one of the new processes by Bear Glass when you can lay down just any design you want on the glass in variety of colors. The resin is applied to the outer layer of glass, using a stained resin machine. Bear Glass applies the resin also to mirrored glass. Traditional handcrafted Resin Stained Glass by Bear Glass has long been recognized for its beauty and dazzling visual impact.

Bear Glass does not use any lead strips in the process of making the Resin Stained Glass but instead uses UV stable, colorfast acrylic resins. The acrylic resin is extremely durable and one can easily compare it with a toughened glass.

Bear Glass can do a whole range of standard Resin Stained Glass designs, still we believe on the visions of our customers. Resin Stained Glass by Bear Glass can really transform a dull back door piece of glass or be used to make a big centerpiece in a landing or hallway. Bear Glass creates beautiful Resin Stained Glass for door panels, windows, fanlights, mirrors etc. The choice of design, color and texture is extensive.

Bear Glass can make faceted glass windows with Resin Stained Glass. Bear Glass artisans use one inch (2.5 cm) thick slabs of glass, cut into the desired shapes then selectively faceted on the interior edges to enhance the refraction of light. Then an epoxy resin is poured between each piece to create the structural matrix. Finally, the resin is covered with a layer of colored granules.

Bear Glass combines the resin stain with silk screening and glass grooving to create even more texture and depth in your design. For came colors you aren’t limited as you are with traditional leaded beveled glass designs.  With Resin Stained glass by Bear Glass you can have red, white, taupe, gun metal, just about any color you want.

One thing to note here is that Resin Stained Glass isn’t a good choice if one just needs a handful of pieces. But for doing multiple pieces this is a beautiful solution for unlimited design capabilities.

One big difference between the Resin Stained Glass and traditional decorative leaded beveled glass is, you can make dual IG units out of them as the Resin stain is applied to tempered glass also.

The advantages of Resin Stained Glass by Bear Glass are:

• Unlimited Design Possibilities: Any design that can be drawn on paper can be reproduced as a stained glass pattern.
• Cost effective: One-half to two-thirds the cost of traditional stained glass, even for one-off designs.
• Energy efficiency: The stained glass pattern can be put directly on modern double or triple paned glass, even on glass that is in a manufactured window sash.
• Cost effective custom work: Computer design and modern manufacturing techniques keep the cost on custom work to about one half the cost of traditional stained glass.
• High volume production runs feasible: The robotic CNC resin dispensing table enables high volume runs with excellent accuracy and reproducibility for every piece.

Patterned glass is a not-perfectly-smooth structure with different patterns impressed on it. The depth, size and shape of the patterns largely determine the magnitude and direction of reflection. Patterned glass or Decorative glass by Bear Glass usually transmits only slightly less light than clear glass. It can be used for a variety of applications like interior design and decorations, furniture, windows, street furniture etc.

Patterned glass by Bear Glass is made with a rolled glass process. All rolled patterned glass begins as a batch of materials, including silica sand, soda, and lime. These materials are melted together in a tank, and then the molten glass mixture is fed onto a machine slab. The glass flows under a refractory gate which controls glass volume and speed then moves between two counter-rotating, water-cooled rollers. One of these rollers is embossed, imprinting a distinct pattern onto the soft surface of the glass while the other roller is smooth.

The result is a piece of glass that is patterned and textured on one side, while smooth on the reverse. The distance between the two rollers determines the ultimate thickness of the glass. After it moves between the rollers, patterned glass is annealed or cooled slowly in order to remove any residual stresses. Rolled patterned glass can then be cut by the expert artisans of Bear Glass into standard sizes or cut into customized sizes for a specific customer application.

Some popular patterns, known as camphor glass, combined the use of clear glass with an acid-finished design.

Basically patterned glass has a pattern impressed on one side of the glass which prevents someone from seeing though it, for privacy. Pattern glass can also be ordered in various tints as well. A common application of this sort is when used in privacy walls to separate one room from another. Patterned glass is not-perfectly-smooth structure with different patterns impressed on it.

Patterned glass by Bear Glass can be used in commercial, residential, office or specialty applications. They have various usage including shower doors and tub enclosures including frameless shower doors, interior partitions, translucent door and window treatments, foyers and vestibules, patio furniture, shelving, decorative furniture, and lighting fixtures. Pattern glass are available in large amount of patterns in Bear Glass stores.
