colour is defined by the reflection of light off a surface. So glass can be said to have no colour as light does not reflect off of it
the light changes colour as some of the wavelengths are absorbed by the coloured glass
Light does not change speed when it goes through glass.
prism. i think.
Its Flame Test:it gives golden yellow colour to non luminous flame which is not seen through a blue glass.
The sunlight hits the glass of water and then the light disperses out as a spectrum of colour (rainbow). This is because sunlight is white light and white light contains the 7 colours of the rainbow. When it hits the glass the colours refract and disperse out as the spectrum of colours, which we see as a rainbow.
Yes all glass can be recycled. The colour of the glass is of a consideration in its ultimate reuse. Clear glass generally segregated from all coloured glass and recycled into clear glass products. Coloured glasses may be accumulated for specific colour uses. Mixed glass will be reused for "brownish" glass uses or for processing into materials such as Fiberglas insulation where colour does not matter.
Glass can be made into an colour by adding the appropriate materials into it.
clear
red
Cobalt

grey
purple
metallic oxides such as those of copper, cobalt, etc are used to color glass.

you mean ornamental glass made in Bohemia in the late 19th Century - the glass has a striated overlay of glass filaments in a different colour
It is used to see the experiment which colour is formed.
