so that the light can be seen by ships
8mm glass is 20KG per sq metre 10mm glass is 25kg per sq metre
A gauge glass may burst depending on the gauge itself. High temperature and pressure situations may cause the glass to burst.
That depends on how the glass is fabricated and finished and the environment it is in, and the type of glass. In general, and approximately, For perfect glass fibers, strength is 500,000 psi (3500 MPa). For polished glass windows, in air, strength is 7000psi (50MPa) For scratched glass, 100 micron deep scratch, it is 2500 psi (20 MPa) For scratched glass in high humidity for several years it is 1000 psi ( 7 Mpa)
NNPB = Narrow Neck Press and Blow. This is a glass bottle forming process,wherein very light weight glass bottles are made compared to the traditional blow and blow process of making glass bottles. NNPB bottles are lighter by around 30% compared to Blow and Blow process,and the bottles produces have evenly distributed glass,and so stronger than blow and blow glass bottles. But this process requires hitech glass forming machinery,expensive mould items and very skilled labour. Most of the renowned glass bottle making companies are now making bottles using this technology.
all materials that are ductile, including almost all metals and plastics. Those materials that are brittle, like glass and ceramics, do not have defined yield points; they simply break
Glass is transparent.
Glass is transparent
Generally clear glass is transparent.
Transparent
No, smoke is not considered a transparent medium because it does not transmit rays of light through it. An example of a transparent medium would be glass.
Maybe you would consider 'I looked through the transparent glass' a good sentence?

Toughened glass is transparent. It is translucent if frosted. To be opaque, it would need to be covered with something that won't let light through.
The opposite of transparent (something that can be "seen-through") is opaque. A glass milk bottle is transparent. The milk is opaque. A plastic milk jug would be semi-transparent.
Two examples if transparent are glass and plastic sometimes (transparent=see through)

Transparent Stained-Glass Windows was created in 2002.
