Stone sinks 1740s - 1780s

There are many styles of stone sinks. This 1740s one by the window is in the Ephrata Cloisters kitchen, Pennsylvania. The second set of images is a stone sink in The Woodlands, c1780s in Philadelphia. Several 1800s descriptions are below. My favorite stone sink in a window will be in a future post.
Food history talks are listed at the end.

Peter Cooper's gelatine

Although Peter Cooper (1791-1883) of New York City may be more well known for designing 'Tom Thumb', the first American steam locomotive that lost a race with a horse in 1830 on the early B&O Railroad line from Baltimore to Ellicott Mills (now Ellicott City, MD). But there is more... Cooper Union, glue, iron and ... gelatin.
