mineral
To distinguish between a mineral with a hardness of 6 and one with a hardness of 4, you can use the glass plate and the copper penny for comparison. First, scratch the mineral against the glass plate; if it scratches the glass, it has a hardness greater than 5. Then, use the copper penny to scratch the mineral; if the mineral scratches the penny, it has a hardness greater than 3. If it scratches the glass but not the penny, it has a hardness of 6; if it scratches the penny but not the glass, it has a hardness of 4.
It's the same thing.
window glass
Mineral that can be scratched with a knife blade or a window glass is gypsum.

The difference between auto glass and regular glass is that auto glass has a thin layer of flexible clear plastic placed between two (or more) layers of glass. The film holds the glass in place when it breaks and will lessen the injuries from broken glass.

glass you can see through and fibreglass you can not

No difference at all. Just the name. Same with "Cocktail Glass" also being known as a "Martini Glass".

i feel' mineral wool is spun out of molten minerals like basalt, volcanics material, (we can also take slag wool a similar material as it comes from furnace as lawa). it is soft. glass wool have more silica in its composition,shines more and white in color ,it is brittle as compare to mineral wool .its fibre length is also more and straight as compare to mineral wool. umesh chitlangia
