Spangle Glass: Victorian Art Glass with Embedded Metallic Flakes

Spangle glass is a type of Victorian art glass containing flakes of mica or metallic particles embedded within the glass body, creating a sparkling, glittering effect when light strikes the surface. Developed in the 1880s, spangle glass was produced by several American and European glasshouses and is sometimes called "mica glass" or "mica-flecked glass." The technique involved rolling the hot glass gather over mica flakes or metallic fragments before encasing them with a second layer of clear or colored glass.

Identification & Makers

The primary American producer was Hobbs, Brockunier & Company of Wheeling, West Virginia, which patented a version in 1883. Other manufacturers include the Northwood Glass Company and various English glasshouses. Spangle glass is identified by the visible metallic flecks suspended within the glass walls, giving pieces an internal shimmer distinct from surface-applied decoration. The mica particles appear as small, flat, reflective spots throughout the glass body. Colors range from amber, cranberry, and blue to green and clear, with the metallic spangles providing additional visual interest. Spangle glass should not be confused with spatter glass, which has colored glass fragments rather than metallic flakes.

Types & Forms

Cased spangle glass: The most common type, with mica-flecked glass encased within a clear outer layer and often lined with white or colored glass. Vasa Murrhina: A related technique patented by the Vasa Murrhina Art Glass Company of Sandwich, Massachusetts (1884), using larger metallic fragments including gold and silver leaf. Single-layer spangle: Simpler pieces without casing. Common forms include vases, pitchers, tumblers, cruets, baskets, and decorative bowls. Many pieces feature applied handles, ruffled rims, and other Victorian decorative elements.

Condition Factors

Check for chips and cracks, particularly around applied handles and ruffled rims, which are vulnerable points. Original stoppers on cruets are essential for full value. The mica or metallic particles should be well-distributed throughout the piece; uneven distribution is a manufacturing characteristic, not a defect, but evenly distributed examples are more attractive. Casing should be intact without separation between layers. Applied handles should be firmly attached. Pontil marks on the base are expected on hand-blown pieces. Surface wear and scratching reduce the visual impact of the internal sparkle.

Collecting Tips

Spangle glass is often overlooked by collectors focused on more famous Victorian glass types, making it relatively affordable. Learn to distinguish spangle glass (metallic flakes inside) from spatter glass (colored glass fragments) and from aventurine glass (a related but distinct technique). Vasa Murrhina pieces with gold and silver leaf inclusions are the most sought-after variety. Cranberry and blue examples tend to command higher prices than amber or clear. Build familiarity with the various forms and handle styles to identify likely makers. Display spangle glass where light can enter the pieces to showcase the internal sparkle. Estate sales and general antique shows are good hunting grounds, as spangle glass is frequently misidentified or underpriced.
