This is an exceptional example of mid-19th-century glassmaking, featuring a deep and vibrant cobalt blue color—a shade historically more difficult and expensive to produce than standard utility glass.

The bottle is free-blown into a classic "chestnut" or mallet-shaped body. The construction exhibits the high "crudity" sought after by collectors, including:

• Rough Pontil Scar: The base features a prominent, sharp, and jagged rough pontil mark, showing where the bottle was snapped from the blowpipe (pontil rod) after the glassblower finished the neck.

• Hand-Applied Ring Collar: The neck is finished with a heavy, "gloppy" ring collar that was hand-applied while the glass was molten, showing the characteristic unevenness and "slop" of mid-1800s craftsmanship.

• Glass Character: The body is filled with "seeds" (tiny air bubbles) and light cooling striations, confirming its early production.
