Cutting Tempered Glass
Can Tempered glass be cut? The answer is no, all fabrication is done before the tempering is done. We cut your glass to your exact size and fabricate all the notches and holes needed. Next we polish the glass which results in a final piece of glass. Tempered glass is normal glass that has gone through heat treatment to increase strength and thermal shock resistance which changes the break pattern to prevent injury. Thermal glass is used where machanical strength, safty, heat and are factors. For example in a fire place doors or on motor vehicles. Tempered glass can withstand constant tempeatures of up to 243°C and when it is exposed to higher temperatures it gradually weakens. A piece of tempered glass that is exposed to temperatures of 316°C or higher will shatter into tiny pieces.
How Mirrors are Made
The term mirror that most of us use refers to a highly refective surface A mirror takes light that hits it and refects it back. The mirrors we see in bathrooms are known as back-silver mirrors. In most modern mirrors aluminum is viewed through a thin layer of glass. The top layer of glass protects the alluminum from bubbling and scratching and it also distorts the image slightly. Over the years neolithic mirrors have been found, they were made by grinding down obsidian rocks then polishing them to an astonishing sheen. These early mirrors allowed even subtle details to be seen clearly in their refelctions. Modern mirrors however are made by taking liquid metals and letting them condese on a sheet of glass which gives you a much better refection than any polishing can achive.
