Compléter The Fascinating World of GlassVersion en ligne Test your knowledge about glass and its various applications in this engaging fill-in-the-blanks game! par Marta Alcaraz González 1 Glass sand soda ash shaped heated limestone is a material made primarily from . To create glass , sand is mixed with and and then at very high temperatures until it melts . Once melted , it can be into various forms .

These ultra - thin strands of glass channel over vast distances with minimal signal loss . The advantage of optical fibers is their capacity for data ; unlike traditional wires which rely on electrical , optical fibers convey information using of light . This method can handle a tremendous amount of data , far outpacing most conventional transmission techniques .
