Art glass bowl in the style of SEA Glasbruk

This item appears to be a medium-sized art glass bowl featuring a vibrant turquoise or cerulean blue body. The glass is characterized by fine, wispy white veining or 'spun' glass threads that create a marbled or swirling effect throughout the translucent blue material. The bowl has a smooth, polished rim and a rounded, vessel-like form. The craftsmanship is consistent with mid-to-late 20th-century Scandinavian glassblowing techniques, particularly the aesthetic associated with Swedish workshops. The owner identifies this as 'SEA Glasbruk,' which is a plausible hypothesis as the bowl is stylistically consistent with the 'Galejan' or 'Wind' series from that maker, though no trademark label or etched signature is visible in the provided image to confirm this attribution. Based on the photo, the condition appears excellent with no visible chips, cracks, or significant abrasions on the rim or interior surface. Without a physical inspection or visible maker's mark, this remains an unverified attribution based on visual style and user-supplied context.

Based on my visual analysis of the provided image, I have examined this art glass bowl which features a distinctive 'spun' white filigree effect over a translucent blue body. The owner identifies this as 'SEA Glasbruk,' a hypothesis that is stylistically consistent with the Scandinavian 'Galejan' series. However, I cannot verify this attribution from a photo as no signature or label is visible; a physical inspection would be required to search for acid-etched marks or specific wear patterns on the base. The value of $45–$85 assumes the attribution to SEA Glasbruk is correct and reflects the current secondary market interest in mid-to-late 20th-century Swedish glass. The bowl appears to be in excellent condition, which is a primary driver of value for glass collectors. In the general market, items of this type often fluctuate based on the vibrancy of the color and the quality of the internal threading. If this piece is found to be a contemporary reproduction or an unattributed 'in the style of' piece from a different manufacturer, the value would likely decrease to the $20–$35 range. To confirm the identification, I would recommend an in-person examination by a specialist in Scandinavian glass and, if possible, locating the surviving manufacturer's sticker or provenance documentation. Until such time, this estimate remains a working hypothesis based on user-supplied context.
