Traditionally, blown glass pieces have been made with clear glass. The molten glass was gathered onto the end of a hollow pipe, and the artist would blow into the other end while using various tools to pull the glass into the desired shape. Modern artists have recognized the desire for color as part of their art form, and it is now becoming common for glass blowers to introduce color to their pieces. This gives them more opportunity for expression, and it adds a new dimension to this art form.
Glass blowers who create small objects may choose only one color for the entire piece, but experienced artists are often seeking new challenges. They may create several smaller blown pieces from different colors and join them by melting select portions of the glass, or the artist may color the glass as they create the piece. When the piece is finished, the artist will have a unique colored glass piece to be admired.
