    Artisans stopped making traditional slag glass in the early 20th century. Some glass artisans continue to call their marbleized glass pieces by the name, but they do not use the same manufacturing process, which used by-products from iron smelting. On 1stDibs, shop a variety of slag glass.
  • 1stDibs ExpertNovember 4, 2024
    To identify a slag glass lamp, study its characteristics. Slag glass is often easy to spot because of its unique swirling pattern and variations in opacity that give it the appearance of marble stone. However, the material is lighter than stone. Certain makers are also known for producing slag glass lamps, such as Bradley Hubbard, the Miller Lamp Company, the Handel Lamp Company and Tiffany Studios. Researching any maker's marks found on your lamp can help you determine if it was produced by one of these companies or by another maker known for its slag glass lamps. Alternatively, you can have a certified appraiser or knowledgeable antique dealer help you make an identification. Explore a diverse assortment of slag glass lamps on 1stDibs.
