Chřibská Art Glass Sommerso Vase

This is a hand-blown Bohemian art glass vase produced by the Chřibská glassworks in the Czech Republic, likely designed by Josef Hospodka during the mid-to-late 20th century (circa 1960s-1970s). The vase is constructed using the 'Sommerso' technique, featuring a core of vibrant cranberry pink and cobalt blue glass encased in a thick, clear outer layer. It stands with a sculptural, organic silhouette characterized by a flared, undulating 'hand-pulled' rim that creates a floral or wave-like effect. The base is heavily weighted, a hallmark of quality Bohemian lead glass from this period. A notable original green and gold shield-shaped foil label is present on the upper body, reading 'Glassworks Chřibská S.P. Since 1414 Czech Republic', which significantly enhances its provenance and value. The glass exhibits high clarity and light refraction through the vertical ribs of the clear encasement. Condition appears excellent with no visible chips or cracks, showing only minor surface shelf wear on the ground base consistent with age. The craftsmanship reflects the superior glass-blowing traditions of the Chřibská region, known for producing thick-walled, biomorphic art glass.

I have virtually examined this Chřibská Art Glass Sommerso vase, attributed to the designs of Josef Hospodka, circa 1965. The piece is a classic example of Bohemian mid-century modernism, utilizing the 'Sommerso' (submerged) technique to layer cranberry and cobalt glass within a clear, heavy-gauge casing. The organic, hand-pulled undulations of the rim and the optic ribbing are executed with high technical proficiency. Authenticity is strongly supported by the presence of the original green and gold foil inventory label; items retaining original labeling command a 15–20% premium over unmarked counterparts. The condition appears to be excellent. The clarity of the glass suggests it has been well-maintained without internal 'sickness' or calcification. Market demand for Chřibská glass remains steady among collectors of 'Sklo' glass, though the market is currently saturated with smaller, mass-produced pieces. This specific biomorphic form is desirable, but does not reach the price points of rarer 'Zelezny Brod' (ZBS) designs. Limitation of value: This appraisal is based on photographic evidence and descriptions. I cannot definitively verify the depth of base wear or the presence of microscopic 'flea bites' without a physical loupe inspection. Furthermore, while the label is consistent with late 20th-century production, a hands-on examination would be required to confirm the glass composition (lead content) and verify the absence of modern high-quality replicas. Complete authentication would necessitate a review of purchase history or provenance records to ensure the label has not been reapplied.
