While not a collector of posset pots (I had to draw the line somewhere) they certainly fall under the umbrella of ceramic feeders in my opinion.
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 did develope an interest in in the later years of collecting was transfer-printed ladies spittoons.
I acquired one early on in collecting because of its similarities with feeding cups (small, having a handle and having a spout) but sadly upon realizing what it really was paid little to no attention to it for the longest time (always kept on the lowest and darkest shelf of the display case).
It was not until much later while downsizing my collection and deciding whether or not to keep it that I decided to acquire a second one to display next to it to see how they looked displayed together - I was hooked ever since.
Another area outside the umbrella of ceramic feeders that I developed an interest in towards the end was transfer-printed inhalers.
While admittedly the vast majority are generic, plain, uninspiring and large there are some that are smaller, with matching lids and beautifully transfer-printed with scenes of flora and birds.
With still no real sense on how they actually work (laziness on my part given most have directions printed right on them) they display wonderfully with all the other medical related items I collected.
American Collectors of Infant Feeders (ACIF) is a small non-profit organization that holds an annual convention (generally in late summer) hosted by one or more of its members and that publishes quarterly informal newsletters entitled "Keeping Abreast".
The organization's main purpose is the sharing of information and the promotion of collecting infant feeders and related items. For those interested please note that "infant feeders and related items" covers alot of territory beyond simply ceramic feeders.
Nothing stated on this website is be considered authoritative. Information shared is simply what I've come to understand and/or believe while collecting & talking to others.
