Cutting Tempered Glass

tempered_glassCan You Cut Tempered Glass? We are often asked if we can cut glass that has already been tempered. Unfortunately, the answer to this question is no. All fabrication is done prior to tempering. That means we cut your glass to your exact size, fabricate any holes and notches needed, miter, then polish the glass resulting in a final piece of glass. Tempered glass is regular glass that has been heat treated to increase strength and thermal shock resistance to prevent injury by changing the break pattern. Tempered glass is used in applications where heat, mechanical strength and safety are a factor. For example, the glass on motor vehicles is tempered to make it strong and less dangerous when it shatters or breaks. Tempered glass is also used in fireplace doors, on masonry and prefabricated fireplaces equipped with a grate to hold the burning wood. Tempered glass can withstand constant temperatures of 470°F. If tempered glass is exposed to higher temperatures, it gradually weakens the structure of the glass thus making it more susceptible to breakage. If a piece of tempered glass is exposed to continuous temperatures of 600°F or more, the glass will shatter into small pieces.

How Mirrors are Made

When most people use the term “mirror,” they are referring to what is known as a plain mirror. A plain mirror takes the light that hits it and reflects it back. Mirrors used for common consumer purposes are of this sort. A mirror is essentially a highly reflective surface. The sorts of mirrors one sees on walls or in bathrooms are of a type known as back-silvered mirrors. This means that the reflective surface–in most modern mirrors this is aluminum–is viewed through a thin layer of glass. The glass protects the aluminum from scratching and bubbling, but also distorts the image somewhat. Early mirrors were created by simply polishing a suitable substance until it became highly reflective. Neolithic mirrors have been discovered, made by grinding down obsidian rocks and polishing them to an incredible sheen. These mirrors have remarkable properties, allowing even subtle details to be clearly seen in their reflections. Modern mirrors, however, are made using an entirely different process. By taking liquid metals and allowing them to condense on a sheet of glass, one can get a surface far more reflective than anything achieved by polish.

SAFETY GLASS:

laminated_glassLaminated – A process by which two or more lites of glass are sandwiched about a polyvinyl layer to give the glass strength against penetration.  It is not shatter proof or unbreakable.  The most common application that everyone should be familiar with is automobile windshields.

Tempered – The process of heat-treating glass, to provide much stronger characteristics than annealed, or un-tempered glass.  Once again, tempered glass is not shatter proof or unbreakable.laminated_glassIt is designed to break into very small pieces to help alleviate severe lacerations.  This process is used on automobile side and rear windows as well as storefronts and doors that are required by local building codes.
