metallic oxides such as those of copper, cobalt, etc are used to color glass.
colour and tone
glass inner colur is blue because silicon gel is used for that one
colour, line and tone
Recurring design elements are elements (features or objects) that are used throughout a design in order to maintain a consistency of design.They can be used to "link" or join features which may be inconsistent or disjointed.Examples of this could include:The use of a common colour or colour schemeRepetitive use of a particular tree in a park or urban planning designThe use of a common motif
The formal elements are Line, Form, colour/tone, Shape/pattern, texture, light and space......
It is used to see the experiment which colour is formed.

The quartz glass used in heating elements is used because it's transparent to infrared wavelengths of light. The glass has no coating whatsoever.

Green colors in glass came from iron. There is a link below.
Common glass is made from clean sand, soda, and limestone. Various other elements may be added to modify the properties of the glass - colour, density etc.
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
Glass consists principally of silica, SiO2, found in sand. This is reacted at high temperature with oxides to form a silicate silica mixture. Coloured glass may have traces of metalic elements, often transition metals, to provide the colour.

Many of the old homes did not have glass in the windows and used shutters instead when they needed protection from the elements.
There are a couple derivatives of elements that are used in borosilicate glass. They are boron oxide and silicon dioxide.
