A D LavoisyScope and Content
This document is a formal printed advertisement or testimonial for a patented mechanical butter churn by A.D. Lavoisy, based on an award received at the 1851 London Exhibition. While the document originated in Paris and London, such innovations were of significant interest to the dairy-rich regions of Orange County, New York, during the mid-19th century, as the county was a world leader in butter production at that time.

MECHANICAL CHURNS.
"Thirteen churns were tried in the first trial, with ordinary cream of good
quality and five in the second. In both trials the churn of LAVOISY did its
work so well that we awarded it a Prize Medal."
"In the first trial, with 2 quarts of cream of good quality, 1-lb 13-oz of butter of
the best quality were produced in 2 minutes, without residue; in the second, the same quantity of cream produced in 45 seconds 2-lb 2-oz of exquisite butter, also without residue." "That result could not be obtained with no other churn."
Mode of employ.
The churn is half filled up, and after having turned it for some time, the
cork placed upon the cover is taken off to let go out the gas formed in the interior. When the butter is made, the catch placed near the small wheel is removed, the wheel is drawn off, the flier is taken away, the butter is taken out, and the churn cleaned up.
N- Before beginning the butter, the churn must be scalded.
Summary
This document serves as a promotional "extract" from the official jury reports of the 1851 Great Exhibition in London. It highlights the superior performance of A.D. Lavoisy’s mechanical churn compared to thirteen other competitors.
Key Points:
Efficiency: The churn produced butter in remarkably short times—2 minutes in the first trial and just 45 seconds in the second.
Yield: It notes a high yield of butter from 2 quarts of cream (up to 2 lbs 2 oz), claiming no residue was left behind.
Operation: The "Mode of employ" describes a mechanical system involving a "wheel" and a "flier," emphasizing the need to vent gas during the process and to scald the equipment for cleanliness.
Historical Context: In 1851, Orange County, NY, was the "Butter Capital" of the United States. High-end dairy farmers in towns like Goshen and Minisink would have been the primary target market for such advanced European mechanical churns to maintain their reputation for "Orange County Butter" excellence.
