While not a collector of posset pots (because of their prices) they certainly fall under the umbrella of "ceramic feeders".
Posset pots are spouted two handled vessels from the 17th and 18th Century used to consume "posset', a beverage containing a cocktail mixture of curdled hot milk or beaten eggs, often including wine or ale, often spiced or sweetened, and often thickened with oatmeal or bread. They have lids to keep the contents warm with the floating custard portion eaten from the top with a spoon and the liquid lower portion sucked from the spout.
They were most commonly made in slipware and delftware and a rare few in silver. Over time the shape of posset pots evolved from simple basic forms to more curvilinear vessels with elaborate ornamentation (too nice to use in my opinion). Needless to say it does not take much imagination to understand why most did not survive undamaged (i.e., wine, ale and ceramics are never a great combination).
One area outside the umbrella of "ceramic feeders" that I developed an interest in later on when collecting is ladies spittoons.
I acquired my first one believing it to be a feeding cup (I was new at collecting, it "sort of" looked like one and it was described as being one) and upon realization as to what it really was I paid little to no attention to it for years. It was not until much later when downsizing my collection (and deciding what to keep vs sell) that I decided to acquire a second to display with it and see what I thought.
Another area outside the umbrella of "ceramic feeder" that I developed an interest in is inhalers.
While admittedly the vast majority are generic, plain and uninspiring - a few have very detailed transfer-printed scenes of flora and/or birds. With still no real sense on how they work (laziness on my part given some have directions printed right on them) they display wonderfully with all my other medical related ceramics.
The American Collectors of Infant Feeders (ACIF) is a small non-profit organization that holds an annual convention each year, generally hosted by one or more of its members, and publishes an informal quarterly newsletter.
For those interested in joining and/or learning more it is important to also note that "infant feeders" encompasses a vast array of items beyond just those found on this website.
Nothing found on this website is to be taken as being 100% absolute. Information shared is simply what I've come to understand, appreciate and/or believe while collecting.
Additionally, all images on this website were posted with educational intent in mind that thus are free to copy and use without permission as far as I am concerned.
