Words that Potters Use, or "Why on Earth Do We Call it Throwing?" By Dennis Krueger

Subsequent to this article, Dennis and I exchanged a few letters, because I'd collected a number of scandinavian and Finnish words related to pottery,  and we also discussed the existence of old norse words in the dialects of northern England.  (much of what I was taught as a child was 'slang' or in some way was not proper english, turned out, when I arrived in Iceland not to be slang at all, but the old norse words still being used by the descendents of vikings who landed a thousand years ago, and built farms, settled the land, married the girls of the Brigantii who were in this land before them.)

Dennis spent many years as a potter, and also founded a business called Krueger Pottery Supply, in 1988, in St Louis, Mo.
I've visited their website, and recommend a visit for U.S. potters.
Dennis Krueger is mostly retired now, but the business is still in the family.


"When a person changes professions one carries the knowledge and experience of the profession left behind into the new profession. In my case the old profession was German language and literature; the new one, pottery. I knew that language, like any other attribute of man, is in a constant state of flux. Anyone who tries to read Chaucer, or even Shakespeare, in its original form can see the enormous changes that have occurred in English just since the Middle Ages. I knew that language has a history just as political events or personalities do, and I knew that most European languages can be traced back to Indo-European roots that actually predate writing.
When I first began making pots, I was naturally curious about the new words I was learning - words which didn't seem to make much sense. Until then, I had thought grog was a rum drink, slip was something 'twixt the cup and the lip, and I wondered why on earth wheel work was called throwing. Since I had the skills in etymology to answer these questions myself, I eventually got around to doing just that.
One of my initial discoveries was of great personal interest. In graduate school, I had been told by one of my professors that Krueger means country innkeeper. Krug (not Stein) is the German word for beer mug and a Krueger is the man who serves beer mugs. This is indeed one definition. The other is that a Krueger is the man who makes beer mugs: Krueger means potter. No wonder I had such an affinity for clay! When I finally explored a larger number of potter's words, some patterns began to emerge. Within the flux of language some areas change rapidly and some resist change. Much of the specialized vocabulary of pottery has resisted change for the simple reason that the activities and objects described have changed so little over the centuries.
I shall begin with the words that appear in Old English (500-1050 A.D.), although many have even older roots.
Clay appears in Old English as claeg and means exactly the same thing it does today. To find the root for clay, we have to go back to the Indo-European root *glei- meaning to glue, paste, stick together.
To throw. Potters at Marshall Pottery in Texas describe their work at the potters wheel as turning. They understand only the modern meaning of to throw and do not use it to describe their work. However, the Old English word thrawan from which to throw comes, means to twist or turn. Going back even farther, the Indo-European root *ter- means to rub, rub by twisting, twist, turn. The German word drehen, a direct relative of to throw, means turn and is used in German for throwing. Because the activity of forming pots on the wheel has not changed since Old English times, the word throw has retained its original meaning in the language of pottery but has developed a completely different meaning in everyday usage. Those who say they throw pots are using the historically correct term. Those who say they turn pots are using more current language. Both are saying the same thing.
Glaze and glass come from the same root - the Old English root glaer, meaning amber. Amber, as everyone knows, is a "pale yellow, sometimes reddish or brownish, fossil resin of vegetable origin, translucent, brittle." (The Random House Dictionary of the English Language, 1967). For the English-speaking world, glass - and with it glaze - must have come into use at a time when amber was a commonly recognized substance. Since amber was a substance much like glass in appearance, the word for amber - glaer - was transferred to the new substance.
Kiln derives from the Latin word culina, meaning kitchen or cookstove. Culina was introduced to England by the Romans in the first and second centuries A.D., managed to survive the Anglo-Saxon invasion of the fifth and sixth centuries, and showed up in the Old English forms cylene or cyline, meaning large oven. Culina has retained this specialized meaning ever since, and nowhere is it used to denote kitchen. Its cousin, culinary, is of much more recent origin. Its first written appearance was in 1638, and its closeness to the classical Latin form indicates that it was reintroduced to English by sixteenth century humanists.
Slip has a history like that of to throw. It derives from the Old English word slype, a relative of slop, and its original meaning is liquid mud. Common usage retains a hint of this meaning in the verb to slip, and in the common adjective slippery. As a noun, however, slip means liquid mud only to potters and ceramists. Everyday language has completely lost the meaning of slip as it is used in pottery.
Pot, potter, pottery. These words do not show up in England until late Old English or early Middle English (1050-1450). There are forms of the word pot in Old Frisian, Middle Dutch, Middle Low German, Old Norse, Swedish, French, Spanish, and Portuguese. However, no forms exist in Old High German or Middle High German. This suggests that the word pot comes from some vulgar Latin derivative of the classical Latin verb potare, to drink. Medieval Latin uses pottus for drinking cup; classical Latin uses potorium for drinking cup; and classical Greek uses poterion for drinking cup. The Oxford English Dictionary, however, disputes this etymology and claims that the origin of pot is unknown. Since the former explanation is better than no explanation, I shall opt for it. Pot comes eventually from the Latin word for drinking cup. It seems likely that the words pot and potter were introduced to England at the time of the Norman conquest (1066). Pottery seems to be a much later addition to English than pot or potter. Apparently it was adopted from the French poterie in the fifteenth century. By the way, the -er of potter means one who makes, and the -ery means the place where.
Since pot, potter, and pottery come into English relatively late, it is logical to assume that they displaced another set of words prior to their arrival. After casting about for a number of possibilities, I hit upon crock, crocker, and crockery, and decided to see how old they are. Crock goes back to Old English crocc - crocca meaning earthenware pot or pitcher - and is related to Icelandic krukka, Danish krukke, Swedish kruka, Old High German krog or kruog, Middle High German kruoc, and German krug! The ultimate origin of crock is unknown. There is a written record of the word crock, dating from about 1000 A.D. Crocker is defined by the Oxford English Dictionary as "potter." The earliest written record of crocker occurs around 1315. The existence of Crocker today as a surname is strong evidence that it is quite old. Crockery is defined by the Oxford English Dictionary as "crocks, or earthenware vessels, collectively earthenware, especially domestic utensils of earthenware." Its earliest written appearance was in 1755. This suggests to me that until the arrival of the Normans in 1066, crock and crocker were the common Anglo-Saxon terms for pot and potter which were pushed aside by the new terms imported by the French-speaking Normans in 1066, but which lived on with a specialized meaning. Crockery, however, seems to be a much later coinage, probably formed by analogy to other nouns ending in -ery. Crockery did not come into common use until the eighteenth century.
Four words whose origins are unknown, but which are probably quite old, are to wedge, bat, grog, and saggar. Their monosyllabic forms would seem to indicate Anglo-Saxon roots, but no evidence exists to prove that one way or the other. Even the Oxford English Dictionary sheds no light on their derivation.
To wedge. The Oxford English Dictionary contains the following under to wedge:
wedge, v. in 7 wage (of obscure origin; the modern form is probably less correct than the earlier wage but cf wedge Sb 4). Trans. to cut (wet clay) into masses and work them by kneading and throwing down, in order to expel air bubbles. 1686 Plot. Staffordish. 123 (Potter's clay) is brought to the waging board, where it is slit into flat, thin pieces . . . This being done, they wage it, i.e., knead or mould it like bread.
The latter part of this entry contains the date, 1686, of the oldest written record of the word. I suspect that the word is much older and that if it is related to wage, it may simply mean something like make, as in the expression "to wage war," but that is just speculation on my part.
Bat. On bat there is even less information than on wedge. The Oxford English Dictionary defines bat as a "lump, a piece of certain substances" and calls its origin obscure.
Grog. As used by potters, grog must be a figment of our imaginations because it is not listed in any of the major dictionaries I consulted. (It is found in An Illustrated Dictionary of Ceramics.) The Oxford English Dictionary lists only the meaning for the rum drink. Perhaps if potters who read this would send sharp letters of protest to the editors of Random House, Oxford English, and other dictionaries, this deplorable situation could be corrected.
Saggar. Saggar seems to be a corruption of safeguard.
Many words are derived from the names of the places they are found, or from the way they are made or used. Ball clay is a type of clay found in Dorset and Devon in England, so named because the clay was cut into balls weighing about thirty pounds. Bentonite is named after Fort Benton, Montana, where it was first mined. China is named after the country of its origin. Kaolin is of Chinese origin and derives from kao ling, meaning high hill - the place it was first found. Faience, the tin-glazed earthenware, was made at Faenza, Italy, in the sixteenth century. maiolica is named after the island of Majorca (formerly maiolica), which was a transfer point for work produced in Valencia, Spain, and exported to Italy. Mishima may derive from the radiating character of certain almanacs made at Mishima, Japan, or it may have been acquired by association with the island of Mishima where the ware was transshipped from Korea. Potash - potassium carbonate - was originally produced by burning wood in a pot. The Dutch coined the term potasch in 1598, and it entered English in 1648. Raku means enjoyment, and the ware takes its name from a seal engraved with this word, which was used to mark early pieces. It is also the name of a series of potters - Raku I-XIV.
The derivations of some words that came into the language in the Middle English period (1050-1450), or later, are quite amusing.
Porcelain. Chinese porcelain was reputedly first introduced to Europe by Marco Polo via Italy. The Italians therefore had the privilege of giving it a European name (although some say it was the Portuguese who named it). They called it porcellana. In French it became porcelaine. The English took it over from the French and dropped the final -e. The Italians probably kept the origin of the word a secret; it is unlikely that the English would have had anything to do with it otherwise. Italian porcellana originally denoted the sea shell concha veneris. This Venus' conch shell is hard and white, and perhaps the Italians named the Chinese ware porcellana because they thought the shell was ground up and used in the body, or because of the similarity in hardness and whiteness. More interestingly, the word for the seashell itself comes from the word porca, pork. The shell was so named because of its similarity to the genitalia of the sow.
Celadon is an equally interesting word. Most of the dictionaries say that the name comes from the character Celadon in Honore d'Urfe's novel Astree. d'Urfe for his part is said to have borrowed the name from the Latin poet Ovid. The character in d'Urfe's novel always wore pale green ribbons. The connection seems tenuous at best, and no one can explain how the name was transferred to a pale green Chinese glaze. An Illustrated Dictionary of Ceramics offers this much more likely derivation: "The name is probably a corruption of Salah-ed-din (Saladin), Sultan of Egypt, who sent forty pieces of this ware to Nur-ed-din, Sultan of Damascus, in 1171."
Stein. When I was an undergraduate student at the University of Freiburg in the Black Forest area of West Germany, I remember being asked by a friend back home to send her a beer mug. I went to a shop and in my best German (which at the time was none too good) I asked for a Bierstein. The saleswoman kept asking me to speak English. I kept refusing because I was determined to speak only German. She only figured out what I wanted when I pointed to the object. Later, I realized that Bierkrug is the correct word, and that Stein means stone. How the German word for stone has come to mean mug in America is a mystery to me. I still feel embarrassment for not having known the difference that day in Freiburg.
Direct borrowings from other languages are common in the English language for pottery. We have already seen kaolin, mishima, and raku. Some others are ceramics, engobe, sgraffito, and temmoku. Ceramic is of recent French origin. It was borrowed from ceramique in the nineteenth century. Its root is the Greek word keram(os), potter's clay. Engobe derives from the French en- plus gober which means, literally, to gulp, take in the mouth, hence to coat something with saliva. From this original meaning to its current sense is not too great a leap. Its earliest appearance in written English was in 1857 in Birch's Ancient Pottery. Sgraffito is borrowed from Italian and derives ultimately from the Greek graphein, to write or scratch. Temmoku is used to describe black-glazed stoneware cups and bowls made during the Sung dynasty (960-1280) at Chien-an (Honan province), China, and so called by the Japanese who sought the ware for use in the tea ceremony. I do not know its meaning or origin.
Modern technology has introduced a number of new words to the language of pottery. Opax, superpax, and zircopax are all based on opacifier. Fiberfrax is from fiber and refractory, kaowool from kaolin and wool. While these are brand names, they are often also used as common names.
Finally, I decided to see where art and craft would lead me. Art goes back to the Indo-European root *ar-, to join. Craft derives from the Indo-European root *ger-, to twist, turn. I was tempted to try to make something out of the difference but gave up the idea, knowing that it would be futile.
In summary, the potter's language has a core of words that go back to Old English roots, and beyond, which have changed little in form or meaning over the centuries because the objects and activities have changed little. Many new words have been added - largely from foreign sources - describing new techniques, new bodies, new technology, or new objects so that there is a continuous enlargement of the core vocabulary: a sign of a healthy and vigorous craft."

One word that appears in Dennis' article is "claeg" as the old-english word for clay. Certainly here in Yorkshire it never died out, my grandfather and father would describe the clay-mud of the ploughed fields as "clag", if it sticks to your boots, in thick, heavy clumps, you might describe your walk as "claggy going".
Thick fog is sometimes referred to as claggy weather, and I've seen pilots write "I could see nothing through the clag".
Back in the days when I did pottery demos and talks, I used to delight in a bit of naughtiness, and shock. There are quite a few naughty things that can be inferred or implied in a pottery demo, the Women's Institute members would go pink, and nudge each other as I coned clay up into a distinctly phallic shape, then pressed it down, forming a spinning globular breast shape, complete with nipple, all the while chatting along about something else. Then when my thumb was lighly touching the nipple and suddenly plunged down, opening the wet mound, there'd often be an audible gasp.
Ladies, I apologise. I was just trying to get you in the mood to spend your money on my pots.
And making you all flustered when I talked about how porcelain's name came from those pink folds....

Well.   Blame Dennis.
