Olive green glass bottle fragment

This object is a small fragment or broken section of a glass vessel, exhibiting a deep olive green or forest green hue. The visible physical characteristics include thick, heavy walls with noticeable internal air bubbles and slight surface ripples, which are often consistent with older, mouth-blown or free-blown manufacturing techniques. Placed alongside a yellow metal tape measure in the photograph, the fragment measures approximately one inch across at the featured edge, though the full dimensions of the complete piece cannot be determined from this view. The glass displays a translucent quality with various textural imperfections throughout the material. There are no clearly legible maker's marks, stamps, or signatures visible in the provided image. The overall visual evidence suggests an antique or vintage utilitarian glass bottle, possibly from the 19th or early 20th century, though such an age estimate remains a stylistic guess rather than a verified fact. The condition shows a sharp, fractured edge where the piece has broken away from the rest of the vessel, indicating severe damage. The identification of this item as a bottle fragment rests entirely on the curved profile and thickness of the glass, without any third-party brand or specific maker attributed to the piece.

Based on what I can see in the photograph, this object appears to be a small, olive green glass bottle fragment, likely dating to the 19th or early 20th century. The thick walls, internal air bubbles, and surface ripples suggest older mouth-blown manufacturing techniques, though I can't verify these characteristics from a photo alone. The piece measures roughly one inch across and exhibits a sharp, fractured edge indicating severe damage. Because this is merely a broken fragment of a utilitarian vessel rather than a complete piece, and lacks any visible maker's marks or stamps, its collector appeal is quite limited. General market demand for unbranded, damaged utilitarian antique bottle shards is relatively low, typically relegated to casual bottle diggers or assemblage artists. The estimated value range of $10 to $25 assumes this hypothesis about its age and material is correct. However, physical inspection would be needed to confirm the glass composition and age. Furthermore, if the piece turns out to be a modern reproduction or decorative shard rather than an actual antique fragment, the value would drop to nominal or zero. A complete authentication process for items of this nature would require in-person examination by a glass historian or antique bottle expert, though the fragmented condition inherently restricts its commercial value regardless of exact age.
