21L Set of Three Art Nouveau White Glass 4-way Box Shank Buttons, 1/2"
These three exquisite Art Nouveau glass buttons, dating to the 1890–1914 era, represent a pinnacle of late Victorian-to-Edwardian craftsmanship. Crafted from fine pressed or molded glass in a creamy ivory/opaque tone (often referred to as clambroth imitation), each features a beautifully raised floral and scroll motif—delicate blooming flowers intertwined with graceful swan-like curves and tendrils, accented by tiny gilt (gold metallic) dots and edging for period elegance.
The design draws directly from Art Nouveau influences, evoking the flowing, nature-inspired lines of artists like Alphonse Mucha, and was likely produced in European centers such as Bohemia (Czech region) or France, where such intricate molded glass buttons flourished during the turn of the century.
The backs reveal classic 4-way box shanks (metal, cross/star-shaped for secure attachment), measuring approximately 21 lignes (21L), or 13.3mm / 1/2 inch—a versatile medium size ideal for blouses, dresses, lingerie, or high-end garments of the time.
Regarding the dark lines visible on the backs: These are typical crazing (fine, web-like cracks in the glass surface), a natural aging characteristic of antique pressed glass, especially milk glass or similar opaque varieties from this era. Glass does indeed develop this over 100+ years due to thermal stress, moisture exposure, or manufacturing factors. In well-preserved antique glass buttons, stable crazing is common, authentic, and often adds to the charm without compromising structural integrity; collectors value pieces with this genuine patina as evidence of age and originality.
These buttons qualify as true antiques (pre-1918) and fall under National Button Society (NBS) Division I (old/antique category), specifically in glass sections for molded pictorial/floral designs—highly regarded in competitive collecting circles.
For serious collectors seeking the highest-end appeal, this matched trio stands out for its rarity as a complete set (matching motifs, size, and condition), strong Art Nouveau aesthetic, gilt detailing, and historical significance.
These are not mass-market reproductions but authentic period treasures, perfect for advanced collections focused on Art Nouveau, pictorial glass, or turn-of-the-century European buttons. Their fine raised relief, subtle translucency, and authentic crazing make them a standout addition for discerning NBS members or private collectors. If you're exhibiting or building a specialized display, these embody the artistry of the era at its most refined.
Measure approximately 21L, 21 lignes, 13.3 mm. or 1/2"
