Slag Lamp

As a kind of pressed glass, slag lamp is admired by collectors worldwide because of its distinctively subtle color and opacity variations. Toward the end of the 19th century and the beginning of the 20th century, decorative pieces made from slag glass were in high demand. It was in the late 19th century during the Art Nouveau period that slag lamps were first produced. Most were cast-iron lamps with a glass shade attached to the base. Several pieces of glass were used in the shade and were connected by metal strips. As a result of iron smelting, glassy slag was formed. Lampshades were made from slag glass, thanks to its aesthetic appeal. In many cases, colored slag glass was used to design slag glass lampshade and bases, and in others to depict everyday scenes. There were often intricate patterns of brass and bronze on the lampshades and shades, such as scrolling floral and foliage patterns, reliefs, and decorative figures. 

Early 1920s fascination with the tomb of King Tut also contributed to the popularity of Egyptian patterns. Slag glass lampshades were often shaped like domes, mushrooms, and flower petals. Besides their beauty, these lampshades and lamps were also treasured for the marbled and colored effect they created on walls. Around the turn of the 20th century, American glass manufacturers (Dugan, Akro Agate, Taylor, Northwood, Westmorland) began producing this type of glass. Also, they began producing caramel slag, an opaque, creamy-golden glass that allowed light to pass through giving an interior a soft, warm, golden hue.
