AI Appraisal Estimate

This item is a decorative hand-blown glass paperweight shaped like an apple, featuring a distinct 'crackle' glass finish. Based on characteristics and form, it is highly indicative of the Mid-Century Modern production by Blenko Glass Company, specifically design #6134. The piece is crafted from clear transparency glass and measures approximately 3.5 to 4 inches in diameter. The construction involves a double-dipped glass process where the molten orb is submerged in cold water to create the internal fracture network, then reheated to smooth the exterior surface. It features a solid glass stem and a broad, curved leaf applied to the top, which are characteristic of Blenko's botanical designs from the 1960s. Despite the absence of a foil sticker or etched mark (which was common for pieces of this era), the craftsmanship and specific shape of the leaf and stem suggest mid-20th-century origin. The condition appears excellent with no visible chips or major abrasions to the outer surface, and the internal crackle texture remains intricate and well-distributed throughout the body, capturing light effectively.

Based on my examination of the item, this piece is identified as a Blenko Glass Company #6134 Crackle Glass Apple paperweight, likely produced during the late 1960s. The 'crackle' effect, achieved via thermal shock, is exceptionally well-distributed, and the application of the leaf and stem aligns perfectly with the known hand-tooling techniques used by Blenko artisans of that era. In the current market, mid-century crackle glass remains a popular entry-level collectible. Similar examples in clear glass frequently sell in the $40 to $75 range depending on the vibrancy of the texture and the integrity of the stem. The absence of a foil sticker is typical, as these were often removed or eroded over time; however, the specific pontil scar and glass weight are consistent with West Virginia glasshouse standards. The item appears to be in excellent condition with no 'flea bites' on the stem—a common fail point for this design. While the form is highly diagnostic of Blenko, full authentication without a label is based on stylistic attribution. A definitive 100% verification would require a physical inspection to verify the specific weight and refractive index of the glass batch, or original provenance documentation such as a 1960s sales receipt. Because Blenko produced this design in various colors, the clear version is less rare than vibrant hues like Tangerine or Turquoise, which slightly limits its ceiling in a competitive auction environment. Nevertheless, it remains a quintessential example of American mid-century functional art.
