Toby Jug

Toby Jug is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Toby Jug rather than just read about it. In short: A Toby Jug, also sometimes known as a Fillpot (or Philpot), is a pottery jug in the form of a seated person; whereas a character jug features the head of a recognizable person. Typically the seated figure is a heavy-set, jovial man holding a mug of beer in one hand and a pipe of tobacco in the other and wearing 18th-century attire: a long coat and a tricorn hat.

Key takeaways

Toby Jug belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Toby Jug to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Toby Jug from memory before moving on to harder problems.

Reference excerpt

A Toby Jug, also sometimes known as a Fillpot (or Philpot), is a pottery jug in the form of a seated person; whereas a character jug features the head of a recognizable person. Typically the seated figure is a heavy-set, jovial man holding a mug of beer in one hand and a pipe of tobacco in the other and wearing 18th-century attire: a long coat and a tricorn hat. The tricorn hat forms a pouring spout, often with a removable lid, and a handle is attached at the rear. Jugs depicting just the head and shoulders of a figure are also referred to as Toby jugs, although these should strictly be called "character jugs" or face jugs, the wider historical term. The original Toby Jug, with a brown salt glaze, was developed and popularised by Staffordshire potters in the 1760s. It is thought to be a development of similar Delft jugs that were produced in the Netherlands. Similar designs were produced by other potteries, first in Staffordshire, then around England, and eventually in other countries, both in Europe and in British colonies.

The Jug in the form of a Head, Self-portrait (1899) by Paul Gauguin is an unusual example from a painter. They were made in the 1760s in the Netherlands.

Etymology There are competing theories for the origin of the name "Toby Jug". Although it has been suggested that the pot is named after Sir Toby Belch in Shakespeare's play Twelfth Night, or Uncle Toby in Laurence Sterne's Tristram Shandy, the most widely accepted theory is that the original was a Yorkshireman, Henry Elwes, "famous for drinking 2,000 gallons of strong stingo beer from his silver tankard, while eating nothing ... He was nicknamed Toby Fillpot, and after his death in 1761 the London publisher of popular prints, Carrington Bowles, issued a mezzotint portrait of him. It became a best-seller — as did the Burslem Potter Ralph Wood's 'Toby' jugs based on the portrait." Toby Fillpot was also the subject of a popular poem, "The Brown Jug", by Francis Fawkes:

Cultural references In the book and 1949 film Twelve O'Clock High a Toby Jug depicting Robin Hood is used as a signal in the officer's club, to discreetly warn aircrews that there will be a mission the following day, without revealing this to outsiders who might be visiting. The Toby Jug plays a pivotal role in the film. A Toby Jug is referenced in the Kingsley Amis novel Lucky Jim. A Toby Jug collector and her large collection also figure prominently in the plot of the 2017 Bravo/Netflix series Imposters.

Worked examples

Example 1 — a first encounter with Toby Jug

Start with the simplest possible case. Write down what Toby Jug claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Toby Jug before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Toby Jug ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Toby Jug

In research: Toby Jug appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Toby Jug in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Toby Jug is common in secondary-school and first-year university syllabi. It links to neighbouring topics Beer vessels and serving, Drinkware, Liquid containers, so understanding it makes those chapters shorter.
In everyday life: Look for Toby Jug outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
