Historical information

The teaspoon is a European invention. Small spoons were common in Europe since at least the 13th century; the special spoons were introduced almost simultaneously with tea and coffee. (Pettigrew points to its use in the mid-17th century.) Originally the teaspoons were exotic items, precious and small, resembling the demitasse spoons of later times. Also used for coffee, these spoons were usually made of gilt silver, and were available with a variety of handle shapes: plain, twisted, or decorated with knobs, also known as knops, hence the knop-top name for such spoons. Widespread use and the modern size dates back to the Georgian era. The teaspoon is first mentioned in an advertisement in a 1686 edition of the London Gazette. Teaspoons, probably of English origin, are present in the 1700 Dutch painting by Nicholas Verkolje, "A Tea Party".

An 1825 cartoon makes fun of a Frenchman unfamiliar with the British etiquette. The guest did not place his spoon into the cup and is thus being offered his thirteenth cup of tea!
A special dish for resting the teaspoons, a "spoon boat", was a part of the tea set in the 18th century. At that time, the spoons played an important role in tea drinking etiquette: a spoon laid "across" the teacup indicated that the guest did not need any more tea,
otherwise, the hostess was obligated to offer a fresh cup of tea, and it was considered impolite to refuse the offering. Pettigrew reports that sometimes the spoons were numbered to make it easier to match the cups with the guests after a refill.
