Glass is old as human old, His need to instru- ments led him to the invention of glass which was known by old Egyptians, Chinese, and our Phoeni- cian ancestors.
The Phoenician Glass is a continuation of the hard working and thinking of Human Beings over thousands
of years to reach the best.
As it is known World Wide, glass is mono- coloured, Every oxide make's one colour, for example, the brown glass is taken from an iron oxide, the blue is taken rom a cobalt oxide, and the red from a gold oxide,If we ried to put all these oxides in one furnace, they will unite and mostly produce the colour of dominant oxide under temperature of (1270) с.
Glass is asubstance that dose not accept mixing with any strange body, Thanks God we could reach an oxide which is made of valuable metals that can mix with glass to produce remain colours fixed forever. This oxide gives us a wide variety of colours, in addition to the two main rare colours wide world which are gold and silver.
