Overview
A massive 10-gallon salt-glazed stoneware crock featuring the iconic blue cobalt 'Keystone' mark. This utilitarian vessel was the backbone of the American pantry, designed for preserving large quantities of food through the winter.
Story
Before modern refrigeration, these crocks were the high-tech appliances of the home. The '10' inside the Pennsylvania keystone symbol isn't just a logo; it's a promise of capacity for a family's entire winter supply of pickles or kraut.
Maker / Origin
The Pfaltzgraff family began potting in York County in the early 1800s, but it was the 1894 factory that revolutionized their output. They transitioned from simple redware to durable stoneware, eventually becoming a household name across America.
Condition & Value
The crock shows a visible vertical crack near the rim and some surface staining. While these 'battle scars' prove its age and use, significant cracks can reduce the value by 50% or more compared to a 'ringing' mint specimen. Condition: Good/Fair. Large capacity crocks (10+ gallons) are highly sought after by decorators.
