TECHNICAL INFORMATION Panel sizes Maximum single panel sizes: • 3100 x 1200mm • CGA001, 002, 003, 004, 006, 007, 008, 009, 011, 013 max 1200mm wide Glass thickness • 4, 5, 6, 8, 10 and 12mm • 15 and 19mm also available Properties Glass types: • Float - glass which exhibits a pale green tint which is more apparent when slumped • Tinted float - green, blue, grey, bronze • High performance tints - dark green, dark blue, dark grey • Starphire® / Optiwhite™ - ultra clear low iron float glass Texturising Texturising is the process of imparting texture and patterns into sheets of glass. It involves intense heat to soften the glass sufficiently for it to melt over and into specially prepared moulds. The heat is provided by kilns specifically designed to suit the glass forming process. The moulds can be a variety of materials selected for their particular characteristics. The resultant glass reflects the artistic input at the design and moulding stage, and the subsequent treatments that might be used. These include colour applications, obscuring treatments, etching, shape-cutting and edging, adhered embellishments and metal-ware. The process of slumping glass on a mould imparts a textural surface on one side leaving the other smooth and glossy, not flat. Random variations in the background texture are inherent in the process. The edges are fire polished and remain flat but slightly rounded. Different moulding techniques can be used to produce patterns incorporating fire polished areas contrasting with obscure texture. Where required for specific glazing situations flat borders can be incorporated. All standard textures are available as toughened safety glass. Tolerances & processing Due to the expansion and contraction during the processing of glass up to 3mm variation in panel sizes may occur. Formed glass can accommodate all standard glass processing treatments such as holes, notches, cut-outs, edge-polishing and cutting (in float form). Safety considerations In glazing situations where Grade A Safety glass is required, Celsius™ formed glass can be toughened to comply with Australian Standards AS/NZS2208 - Safety Glazing Materials for use in Buildings (Human Impact Considerations) and AS1288-2006 � A Grade Safety Glass. It should be noted that the toughening process may impart some slight "bowing" over the length of the panel, or in some cases, ghosting marks caused by the furnace. These are unavoidable and add to the individual nature of slumped glass. Custom techniques Intermediary Intermediary custom techniques are where texture and pattern merge into clear transparent glass within the same sheet. Situations that can benefit from this treatment include feature panels that can seamlessly be incorporated into larger areas of clear glass. Views can be controlled, both in and out, to maximum advantage. Entry-ways, shower screens, windows and privacy screens are also given added intrigue. Glass fusion Glass fusion is a process for creating a single panel of glass from multiple small pieces. Various pieces of coloured glass and/or clear glass are cut to a predetermined design and heated to temperatures in excess of 800oC. This process is used in art projects, embellishments, platters, bowls and lighting, and cannot be toughened. Glass colouring Cold treatments - applied two-pac This process is primarily used on glass panels for wall-cladding, such as splashbacks. It is also the best method for true colour representation in signage and corporate branding. Celsius™ also has developed a unique paint process, that from a distance appears solid, but in actual fact is translucent, and dependent on light situations, can be used in privacy situations. Note: Where a true paint colour is required it is necessary to use Starphire® or Optiwhite™ Ultra Clear glass as this allows for the most accurate colour reproduction. Sandblast/etched glass This technique is used to create one off artworks featuring multi-layered carved glass to create 3D images. It can also be used with textured glass to provide additional details, or obscuring treatment. Bending and curving Bent and curved glass panels can be produced in a variety of finishes. This complex procedure requires special bending moulds and strict firing conditions. Bent glass can be toughened, and also laminated for safety purposes. Airbrushing This is a custom technique that allows almost unlimited options. Celsius™ use airbrushing mainly for the colouring of embossed logos. The colour choice is wide and varied, with the finish being first class. Maintenance and cleaning Slumped glass / formed glass Slumped glass is cleaned in the same manner as ordinary glass however a natural bristle brush may be used on the textured surface if required. Float glass with fired vitreous paint The paint has been fired onto the glass at temperatures in excess of 550oC making it highly durable for use in exterior situations. Any normal commercial glass cleaner can be used with a lint free cloth, or a solution of methylated spirits and water mixed into a spray bottle to a ratio of roughly 1 to 5. * Never use a scouring pad or scraper or even a coarse cleaning product, such as Ajax or Jif, as this will scratch the glass. Glazing considerations All slumped / formed glass products can be installed by local glazing contractors using standard methods and fixing systems in the same manner as flat glass of equivalent thickness. However due to the textural surface of the glass, suction lifters are generally not able to be used. Where required for specific glazing situations flat borders can be incorporated. Refer to Australian Standards AS1288 - 2006 (Glass in Buildings - Selection and Installation) for glazing methods and recommendations. Interior/exterior Generally panels are glazed with the smooth surface to the exterior of the building for ease of cleaning. In shower screen applications, this would be reversed, with the smooth side glazed to the inside of the screen, again for ease of cleaning. Where this is not a consideration however, one has a choice based entirely on aesthetics.
