Tempered
Glass is a type of glass that is made stronger by chemical techniques which
also render it safer than the normal glass. Normal glass breaks up in to
dangerous little pieces which may cause harm in many ways. This type of glass
is especially used where human contact prevails, like doors, car windshields.
This glass, though tough has special cleaning methods, which if not practiced,
may scratch/deform the glass. Here are the ways to clean and test the glass.
Cleaning:
Cleaning
a tempered glass requires care because though tough, it scratches very easily
if abrasive material is used for cleaning. Here are listed steps to clean it
effectively.
First of
all, check whether the solution used is not harmful for the glass by applying
the mixture on a corner of the material. We should never use hard materials in
scrubbing it. This puts unwanted scratches on it. Always use dish soap and
water for the solution. Mix equal quantities of the ingredients and spray them
on the surface. Give the mixture sometime to settle down on the glass and mix
with the dust. This makes it easy for the scrubbing and effectively takes off
the stains. Use a very soft pad for scrubbing the glass, for even a nylon pad
with abrasion can cause scratches. Spray on stubborn areas twice or thrice to
make the stain go away. Never use Teflon or other metallic pads to wipe the
surface.
Testing:
Tempered
Glass is not easy to differentiate from the normal kind because it looks no
different than the normal one. Tempered Glass is made in such a way so as to
make it five times stronger than the normal ones. Doors, windshields and
similar places where human contact is high are fitted with Tempered Glass.
Adding to its features, this glass is designed to break up into oval pieces
which are much less harmful than the normal type which breaks up into little
edgy pieces. To check it, we should follow these steps.
We can
check the hardened patterns by testing it under the sunlight, while wearing
sunglasses. The hardened pattern is not uniform throughout the material. The
easiest test is to feel the glass carefully. If we experience the glass to be a
little rough, then we can say to some degree that it's tempered. Tempered glass
appears to be a slightly bent if observed closely. This occurs because of the
hardening by heat. There should not be chipping or cracking. If so, it would
break if it is a Tempered Glass. Some types come with an etching in the corner
stating that it is tempered. This is a satisfactory sign for it.
