The stylistic trend for early to mid-20th Century glass closely mirrors the general changes and trends in design for the era. In the early 20th Century Art Deco and other movements, including Bauhaus began the trend of simple lines and a move away from elaborate ornament. Victorian styles were ornate and richly embellished. The embellishment was achieved with painted glass, cut glass, cameo glass or simply in the form with embellishments in the overall design of the piece of glass. In mid-Century we see glass forms became more sleek and streamlined. The shape and color become more important than the ornamentation and decoration of the glass. The shapes become more organic, and overall the pieces are more sculptural, and abstract. If classic forms are used, they are taken and re-interpreted with this modern aesthetic in mind. Depending on the country you are referencing, glass use could be lost completely, or the design could be modified with the aim of ease of daily use.
