This is an American Brilliant Period (ABP) cut crystal glass pitcher, likely produced between 1876 and 1914.It features intricate geometric designs,including hobstar and fan patterns, characteristic of the era.The piece has a sawtooth rim and a handle with notch cuts.Authentic pieces from this period are heavy and highly brilliant due to high lead content in the glass.

That base configuration is a definitive trait of high-end American Brilliant Period (ABP) crystal. In antique cut glass terminology, a multi-pointed star featuring a precision-cut, cross-hatched center is known as a hobstar rosette.

The notched handle confirms that it is an authentic piece of handmade American Brilliant Period (ABP) cut glass rather than a mass-produced imitation.

The "Applied" Technique: In the late 19th and early 20th centuries, handles were not molded as part of the pitcher body. Instead, a master glassblower attached a separate, glowing-hot rod of molten lead glass to the blown pitcher base by hand, pulling it upward to form the loop.The Intricate "Notching": Once the applied handle cooled down completely, a master cutter manually held the heavy glass against a rapidly spinning iron or stone wheel. They carefully carved out each individual horizontal groove—often called step-cutting, notch-cutting, or thumbprint facets.

We see two or three tiny air bubble inclusions in the glass near the spout. See last photo.
