Light Green Umbrella Ink Bottle

Features

• Shape: It has the classic octagonal base and sides that taper sharply up to the neck, giving it the distinctive “umbrella” or “pyramidal” shape. This shape was popular because it was less likely to tip over.
• Color: The glass is a light green, a color often resulting from impurities in the sand used to make the glass, such as iron.
• Base: It has a smooth base. The bottom view shows a slight indentation or pontil mark remnant in the center, and concentric circles (mold marks) which may suggest it was made in a plate mold or a variation of a two-piece mold. The absence of a rough, heavily scarred pontil mark suggests a production date after the mid-1800s, possibly from the 1870s to the 1890s era of automatic bottle machines.
• Lip: The finish on the neck is an inward rolled lip (or rolled finish), which is a characteristic feature of many ink bottles designed to accept a cork.
• Glass Characteristics: The glass shows typical signs of early manufacturing, including numerous small bubbles (seed bubbles) and striations or flow lines, especially visible on the neck and body, indicating it was blown in a mold.

This type of ink bottle was mass-produced for home and office use in the late 19th century.
