It's over 5000 years old and still making history. Archaeological findings suggest that glass was first used around 3500 BC. Since then, a great deal has changed. Glass however remains a popular material used in a wide range of applications – one of which is interior design. Glass can be formed into almost any shape and coloured virtually any shade, so it's no wonder that designers love to make use of this raw material on a regular basis. For Gira, too, glass plays an important role in product development; the Gira Esprit design line is just one example of where the material is used. The frames in this line have a coloured black, white, mint or umbra background, creating new and interesting effects on dark and light surfaces. The C grinding process can also be applied to round the edges.
