Question: When is a comport something else?
Answer: When the glass company calls it something else
Let’s look at a few examples.
Comports or compotes are stemmed bowls, shallow with wide rims, meant to hold candy or flowers or candles. Originally the term “compote” meant stewed fruit, a dessert, which people served in pieces with long pedestal stems for a fancier look.
This electric blue twisted stem comport is from Fostoria, made about 30 years before than the Rose Point one. Its bowl is flared and shallow. (Find it here on Etsy.) You can visualize putting a candle surrounded by greenery in this.
Cracker and cheese sets have small, short comports to hold the cheese, usually called a cheese dish or cheese comport.
You might find these without their matching flat plates that originally were used under the cheese dish to hold the crackers.
Mayo bowls from older patterns often are short, wide bowls, usually deeper and more bowl-like than the usual comports. Usually they were part of a set, including the matching under plate and a ladle.
Mayos from more recent glass patterns often are footed, and have no stem, as with this Fostoria Chintz mayo.
Cambridge made many mayo bowls, including this rather unusual one, the 3900 shape etched with Rose Point.
I hope this helps explain the difference among these different pieces, all of which are “comports”!
