Mid-Century Slag Glass Goblet

This item is a stemmed goblet crafted from slag glass (also known as marble glass or mosaic glass), a type of opaque glassware characterized by its multi-colored, swirled appearance created by mixing different batches of molten glass. The aesthetic of this piece is dominated by a dramatic marbling of deep amethyst or charcoal black swirls integrated with milky white and translucent lavender-hued streaks. The physical construction consists of a wide, slightly flared bowl that tapers into a rounded base, supported by a short, pedestal-style stem and a circular foot. A notable physical feature is the prominent vertical seam line visible on the bowl and base, which indicates that this item was produced using a press-mold manufacturing process, common in mass-produced American art glass from the mid-20th century. The marbling is most intense at the rim and tapers into darker concentrations at the base of the bowl. Regarding condition, the goblet appears structurally intact with no large chips or cracks visible along the rim, though the glass surface shows a faint patina of dust and some minor surface artifacts typical of mold-blown glass. The craftsmanship is consistent with decorative household glassware from the 1950s or 1960s, a period when slag glass enjoyed a revival in popularity through manufacturers such as Imperial Glass, Westmoreland, or Fenton.
