You must have seen smart phone, Smart watch,etc.

why not a glass to be Smart......

Lets see how is "SMART GLASS"

SMART GLASS•As name suggests this is smart glass due

to its refracting as well as reflecting property.

HOW TO SEE THE EFFECT IN THE GLASS

• 1.Place the object in front of the glass2.You will see the object in the glass3.Now tilt the glass, you are able to see the objects behind the glass now!

HOW DOES TRANSPARENCY WORK??

INGREDIENTS•Silica is major ingredient as being kind of the

glass.

•SILICA( SiO2)-about 70percent•other ingredients are added according to the

demand of the colour

Chromium is added if green colour is required

Manganese is added to give purple colour to the glass

How glass is manufactured??

•The main idea behind the magic of this glass is, transition metal hydride creates reflective face in place of absorbent face

•Which causes partially reflecting and when tilted transparent.

1. Simple glass is taken

3.A LAYER OF TRANSPARENT MATERIAL IS APPLIED ON ONE SIDE

2.A thin film of switchable mirror glass is applied on this glass.

4.At last the glasses are sealed by sealing material

Advantages•This glass is skin friendly that will keep the UV radiations outside the house protecting your family

•2 effects are produced on the same glass which makes it smart

•This glass is available in many colours.

Comparison

2.multiple effects can be seen in same glass

OTHER GLASSES

1.plain glass is very cheap

2.they are functioned for only single purpose.

$Cost$•Smart glass or switchable glass is slightly

costier than normal glass.•The reason behind this is the coating &

sealing processes involved in the manufacturing glass.

•The cost is US$2- US$20/Sq. metre means approx. Rs.120-1200/Sq. metre

•but still if u want better & attractive looks in your interiors and windows you have to pay for it.
