Copper courses. Profession coppersmith

Coppersmith is one of the oldest human professions associated with metal processing, and has a thousand-year history. The name coppersmith comes from the word copper. The professional orientation of a coppersmith is the processing of copper alloys (copper, brass, bronze) using metalworking and soldering methods.

THE ART OF COPPERWORKER

“I've been told more than once that I'm an endangered species,” says Dennis McBain, the only coppersmith on staff at the distillery in Scotland. Dennis began his career more than fifty years ago at the Balvenie distillery - he followed in the footsteps of his father, who also worked there at one time.

Coppersmith is a very rare profession that requires special skills. This craft is one of five unique ones preserved at the Balvenie distillery. Thanks to the careful preservation of these unique skills, The Balvenie single malt Scotch whiskey acquires its complex taste with characteristic honey tones.

Originally, when Dennis McBain joined the distillery in 1958, he worked in malt production. His “professional image” began to take shape a year later, when he became an apprentice to coppersmith Willie McLachan, well-known in the Scotch whiskey industry at that time. At the age of sixteen, Dennis began training in this amazing profession, which lasted six years. After passing the exam, in which he had to demonstrate all the professional skills he had acquired, he could begin to receive a specialist's salary - which was, no less, one penny an hour more than before. Willie McLacan retired in 1978 and handed over the reins to his apprentice, who, 22 years after joining the distillery, became The Balvenie's full-time coppersmith.

While much of what Dennis McBain does remains the same as in the old days, some things have changed over the past half century. The most noticeable changes affected the heating system of the cubes: when Denis first started working as a coppersmith, they were heated with coal, but now - with steam, which means a significant reduction in time and physical costs for their maintenance. After all, coal is a larger amount of dirt and abrasive particles. In addition, until 1972, stills were made directly at the distillery. For example, the bottom of the recently replaced mash still number two was once part of a still that Dennis made entirely himself over thirty years ago. That cube had thick walls, was very durable, and served faithfully for more than forty years.

The stills used at the Balvenie distillery are unique in both size and shape. Their unique design, called the 'Balvenie Boil Ball', maximizes the surface area of ​​the unit, resulting in a sweeter and richer flavor of the spirit.

Dennis's task is to monitor the condition of the stills - who else but him will notice that it is time to replace this or that still. The master has a number of tools in his arsenal that help him “put in order” copper devices. Among them are metal and wooden hammers of different sizes, shapes and weights, various soldering irons for forging copper and giving it a certain shape.

“You should have a clear idea in your head of what the finished product should look like. You don’t just need to hit copper with a hammer and hope that what you need will come out of it,” says Denis McBain about his work.

The profession of a coppersmith means that he regularly checks the condition of the distillation cubes, how worn they are, and whether they will leak in the near future - then they will need to be repaired. When Dennis walks around the premises where the cubes are located, he always talks with the distillers, who promptly inform him about possible problems in the cubes, if any.

In addition to repairing and maintaining the stills, Dennis also oversees the distillation process: he has extensive experience working in the distillery and knows absolutely exactly what is happening at any given moment in the still or condenser. He has developed a special sense that allows him to accurately assess how the distillation process is proceeding.

“When you work day after day and improve your professional skills, a certain inner feeling develops, an instinct that tells you what is what. Talk to other distillery workers - they will tell you the same thing."

“Of course, we can’t do without science in our business, but what I’m talking about gradually becomes second nature to you, and one day you start working based on intuition, which is honed to mastery, like everyone else in the profession fifty years later.”

In addition to the usual routine procedures that a coppersmith carries out every day, there are those that Dennis resorts to, as they say, on occasion. One of them is called “sweetening the still” in the language of the Balvenie distillery coppersmith: before the main distillation process begins, a handful of finely chopped juniper branches are placed into the still. As Dennis himself says, “There’s no science to it,” but he’s convinced that it ultimately gives the whiskey its distinctive flavor.

Another procedure is called “plug on a rope.” It helps the coppersmith determine how much foam has accumulated inside the mash distillation apparatus. Dennis swings a rope with a cork at the end, it touches the cube and by the tone of the sound he determines whether there is a lot of foam inside. A simple but effective method that Dennis McBain recommends to all his colleagues. And another proof that the traditional craft continues to live.

Denis talks with a smile about another, informal tradition. “In the old days, the craftsmen who worked at the distillery had a so-called “dog”, which was a piece of copper rolled into a cylinder that could be lowered into the barrel and scooped up some whiskey. This design was called a “dog” because the copper cylinder hung on a chain, just like on a leash, and, of course, was man’s best friend!”

“When the manager was not around, they filled this cylinder with whiskey, hid it in their trouser leg - and so, at home in the evening there was something to drink. This, of course, is a little risky, because if you are caught with such a “dog” in your trouser leg, you will be instantly fired.”

Dennis says that what helped him stay in the profession for all these many years was his love for his work and the people around him at the distillery. He also has an excellent sense of humor. One has only to see his work gloves, on which the word “Menace” is written, which means “danger”, and you understand that he is the keeper of such a valuable and rare craft that he does not take himself seriously.

Excerpt characterizing Mednik

- Gentlemen, this is nonsense; he will be killed to death,” said this more prudent man.
Anatole stopped him:
“Don’t touch it, you’ll scare him and he’ll kill himself.” Eh?... What then?... Eh?...
Dolokhov turned around, straightening himself and again spreading his arms.
“If anyone else bothers me,” he said, rarely letting words slip through his clenched and thin lips, “I’ll bring him down here now.” Well!…
Having said “well”!, he turned again, let go of his hands, took the bottle and brought it to his mouth, threw his head back and threw his free hand up for leverage. One of the footmen, who began to pick up the glass, stopped in a bent position, not taking his eyes off the window and Dolokhov’s back. Anatole stood straight, eyes open. The Englishman, his lips thrust forward, looked from the side. The one who stopped him ran to the corner of the room and lay down on the sofa facing the wall. Pierre covered his face, and a weak smile, forgotten, remained on his face, although it now expressed horror and fear. Everyone was silent. Pierre took his hands away from his eyes: Dolokhov was still sitting in the same position, only his head was bent back, so that the curly hair of the back of his head touched the collar of his shirt, and the hand with the bottle rose higher and higher, shuddering and making an effort. The bottle was apparently emptied and at the same time rose, bending its head. “What’s taking so long?” thought Pierre. It seemed to him that more than half an hour had passed. Suddenly Dolokhov made a backward movement with his back, and his hand trembled nervously; this shudder was enough to move the entire body sitting on the sloping slope. He shifted all over, and his hand and head trembled even more, making an effort. One hand rose to grab the window sill, but dropped again. Pierre closed his eyes again and told himself that he would never open them. Suddenly he felt that everything around him was moving. He looked: Dolokhov was standing on the windowsill, his face was pale and cheerful.
- Empty!
He threw the bottle to the Englishman, who deftly caught it. Dolokhov jumped from the window. He smelled strongly of rum.
- Great! Well done! So bet! Damn you completely! - they shouted from different sides.
The Englishman took out his wallet and counted out the money. Dolokhov frowned and remained silent. Pierre jumped onto the window.
Gentlemen! Who wants to bet with me? “I’ll do the same,” he suddenly shouted. “And there’s no need for a bet, that’s what.” They told me to give him a bottle. I'll do it... tell me to give it.
- Let it go, let it go! – said Dolokhov, smiling.
- What you? crazy? Who will let you in? “Your head is spinning even on the stairs,” they spoke from different sides.
- I'll drink it, give me a bottle of rum! - Pierre shouted, hitting the table with a decisive and drunken gesture, and climbed out the window.
They grabbed him by the arms; but he was so strong that he pushed the one who approached him far away.
“No, you can’t persuade him like that for anything,” said Anatole, “wait, I’ll deceive him.” Look, I bet you, but tomorrow, and now we're all going to hell.


There were a variety of professions in Rus'. Some have already disappeared and remain only in ancient books; some still exist today. And there were also those whose names - tselovalnik, hooker, ofenya and others - are currently known to few and cause surprise.

The kisser who did not kiss, but demanded money

The profession with such a romantic name belonged to the financial field. Taxes and execution of court decisions were the main areas for which the kisser was responsible. He was also entrusted with populated areas and areas for police supervision.

Kissers were elected. This position was first mentioned in the Judicial Charter of 1497, and it existed until the 19th century, when it began to be called a “bailiff”. After the elections, an appointment ceremony was held, at which the kisser had to take an oath of allegiance and honor, and kiss the cross. That's where the name came from.


In essence, these were officials who worked under the supervision of zemstvo bosses. However, strict requirements were applied to their work, and, in addition, unlike modern employees, kissers bore full responsibility for their actions. The main requirement that had to be fulfilled was an increase (or, in extreme cases, unchanged) in the amounts of duties, taxes and arrears compared to the previous period. Less money - please pay the arrears out of your pocket, otherwise you will be in debt to the treasury. This is how the government ensured the flow of finance.

The saddler who "dressed" the horses

Today the adjective “blindsided” is used quite often. By this they mean a person who is distinguished by stubbornness, inability to perceive and adequately evaluate people’s opinions that differ from his own. In fact, blinkers are an element of harness, namely special eyecups. They were intended to cut off vision - the horse had to look forward and not be distracted by what was happening to the left and right of it.


Thanks to blinkers, the name of a profession in demand in Rus' appeared - saddler. Such craftsmen made not only blinders, but also bridles, saddles, and stirrups. It was a responsible and difficult task, since the horses were treated with great attention, they tried to maintain them correctly so that they would serve as long as possible.

Today, saddlers still exist, but naturally there are far fewer of them. They make harnesses for expensive thoroughbred racehorses, so the requirements for them are appropriate.

A hooker who received disability at the age of forty

This was the name given to a hired worker in the 18th - early 20th centuries who carried heavy loads. For this, an iron hook was used, which served to lift a bag or sack. The load was held on a saddle, which was a support with canvas straps worn on the back.


The workers had to endure weights that only trained weightlifters can do today. The weight could reach two hundred kilograms. Naturally, such loads did not pass without a trace - due to wild muscle tension and pressure on the spine, people developed hernias, the supporting apparatus suffered, and severe chronic pain arose. There were frequent cases when the hooker lost his balance and fell, including into the water (when unloading cargo ships), which led to injuries, concussions, and mutilations.

Such work led to the fact that by the age of forty, hookers became “ruins”, and many received disabilities.

Why did people choose this profession despite the risk? It was all about money, since with vigorous activity and favorable weather conditions, the hooker’s earnings were very high and reached 5 rubles a day. Unfortunately, when it rained, there was a snowstorm or a hurricane blew, that is, the weather was not suitable for loading and unloading operations, the hookmen spent their time in taverns, where they safely drank away their hard-earned money.

Coppersmith, ancestor of the welder

Naturally, the name of this profession comes from the word copper. The coppersmith was engaged in processing alloys from this metal, using various metalworking methods and soldering. Making copper objects required special skill, professional skills and considerable physical effort.


Copper workers were also called tinkers, soldering workers, and they gave rise to the development of the welding profession. Their work was in demand, and there were always plenty of orders - household items were worn out and required repair or replacement.

The profession of coppersmith is very ancient. Its representatives worked with thin sheet metal, which required a precise eye and skillful hands. It is interesting that even today such work is very difficult to automate, therefore true craftsmen who understand the line between craft and art are highly valued.

Ofenya, who invented the picaresque language

Such a funny name was given to wandering traders, of whom there were always many in Rus'. They walked around the villages and offered the population fabrics and pictures, books and jewelry, household items and other goods.


It cannot be said that the peasants were very fond of the ofeni, since they managed to make a colossal markup on goods. However, having heard the loud cry of the merchant (and the ability to invite customers and “sell” something to them was considered the key to success in this profession, which was passed on from generation to generation), people rushed to him. It wasn’t even about the baskets and trays of goods, but about the fact that the ofenya could bring interesting gossip and news. Why not modern radio? With jokes, jokes, telling about incidents, amusing buyers, the women skillfully sold the goods from their hands.

They even had their own society, a kind of charter and their own slang, which was called fenya. Today, many people use this term, considering it a prison term, although it was invented by cunning traders. If you remember Vladimir Dahl, he spoke about fenya as a language for trickster meetings of traders. Some words are still used today, for example: tinker - to do, bust (thump) - drink, pohanya (converted to pakhan) - master.
