Art glass refers to decorative glass objects created primarily for aesthetic purposes rather than functional use. This type of glass can include vases, sculptures, and ornaments, often showcasing unique designs, colors, and textures. Artists use various techniques, such as blowing, casting, and fusing, to create these pieces, making each one distinct. Many art glass pieces are produced by skilled artisans or studios, such as Tiffany Studios or Murano glassmakers. The value of art glass can vary significantly based on the artist's reputation, the complexity of the design, and the materials used. Collectors often seek out these pieces for their beauty and craftsmanship.
