Victorian-era slag glass vase with purple and white swirls. 4” X2” Circa 1890-1910

Slag glass, also known as malachite glass, is a type of colored glass that contains streaks or swirls of opaque white, blue, or purple, resembling the slag from a furnace. It was particularly popular during the Victorian era, from the late 19th century through the early 20th century, for decorative items like vases, bowls, and tableware. Its appeal lay in its unique, marbled appearance, which made each piece distinct. Fenton Art Glass Company, founded in 1905, became renowned for its production of slag glass, often referred to as "carnival glass" or "milk glass" depending on the specific type. Their pieces are highly collectible today, appreciated for their craftsmanship and the vibrant, swirling colors achieved through their glassmaking techniques. This particular vase, with its purple and white swirls, fits the typical aesthetic of Victorian-era slag glass.
