Copper pans are made using one of three methods: spinning on a lathe, forming in a press, or rolling by hand. In the past, copper was worked by hand with a hammer, but this is no longer a common practice due to its labour-intensive nature. Today, copper pans are typically spun on a lathe, where a blank disc of metal is pressed with a roller that gradually bends it into the desired shape. This process requires training and skill to control the roller's pressure and speed manually. Alternatively, copper pans can be formed in a press, which requires little skill as manufacturers simply place a blank of copper on a form and press a button. For more unusual shapes, copper sheets may be rolled or bent into position by hand and then joined at the seams. Once the desired shape is achieved, handles are attached using copper rivets.
How Copper Pans Are Made
| Characteristics | Values |
|---|---|
| Ancient method | Copper was worked by hand with a hammer |
| Modern methods | Spinning on a lathe or forming in a press |
| Lathe process | A blank disc of metal is set on a lathe next to the chuck, which determines the size and shape of the pot. As the lathe spins, the copper is pressed with a roller that gradually bends it over the form until the desired shape is achieved. |
| Lathe process challenges | Requires training and skill due to the manual control of roller pressure and speed, which can result in uneven, lumpy sides if not executed properly. |
| Press process | Requires minimal skill; manufacturers place a blank of copper on a form and press a button, allowing a mechanical arm to force the copper down over it. |
| Quality comparison | No real difference between spun and pressed copper cookware |
| Rolled copper | Sheets of copper are rolled or bent into position by hand, and then the seams are joined. |
| Hammer marks | Historically, hammer marks indicated that the pan was pounded by hand to form, harden, and strengthen it. Modern hammer marks are decorative and done by machine. |
| Handle attachment | Handles are typically mounted with copper rivets, which are placed through drilled holes in the handle and pot, heated, and hammered into place. |
| Handle materials | Cast iron is the most common and traditional material, but brass has also been used. |
| Copper reactivity | Copper is very reactive and should be avoided when cooking acidic foods. |
| Copper advantages | Excellent heat conductor, ideal for delicate foods and gas stoves. |
| Copper maintenance | Copper cookware requires the application of fresh tin after extensive use. |
| Copper pricing | Handmade copper pans can be expensive, ranging from $200 to $1500. |

Copper pan production methods: spinning, pressing, or rolling
Copper pans are made using one of three methods: spinning on a lathe, forming in a press, or rolling. In ancient times, copper was worked by hand with a hammer, but this method is rarely used today due to its labour-intensive nature.
Spinning
Spinning copper begins with a blank disc of metal, which is placed on a lathe next to the chuck—a form that determines the size and shape of the pot. As the lathe spins, the copper is pressed with a roller that gradually bends it over the form until the metal takes on the desired shape. Spinning copper requires training and skill, as the roller's pressure and speed must be controlled manually. To spin a pan well, the roller should move at a consistent pace, which can be difficult when the lever shifts.
Pressing
Pressed copper, on the other hand, requires minimal skill. Manufacturers place a blank of copper on a form and press a button, causing a mechanical arm to descend and force the copper down over it. There is no significant quality difference between spun and pressed copper cookware. However, some producers pride themselves on using the more demanding spinning technique.
Rolling
Some copper pieces are neither spun nor stamped but are instead made by rolling. In these cases, sheets of copper are rolled or bent into position by hand, and then the seams are joined. This method is sometimes used for large stockpots or unusual pan shapes like boxy fish poachers.
Finishing
Regardless of the forming method, the handle is typically attached to the copper vessel after it has been shaped. The handle is usually mounted with copper rivets, which are placed through drilled holes in the handle and pot, heated until softened, and then hammered into place. The interior of the pot may also be lined with a non-reactive metal, such as tin or nickel, to prevent the copper from reacting with acidic foods and causing discolouration and a metallic taste.

Lining options for copper pans
There are several options for lining copper pans, each with its own advantages and disadvantages. Here is a detailed overview of the most common lining options:
Tin
Tin is a popular choice for lining copper pans due to its excellent thermal conductivity. When tin and copper are heated together, an electron exchange occurs, allowing the copper to transfer heat efficiently through the crystal structure of the tin. This results in faster and more even heating. Tin-lined copper pans are also non-stick, energy-efficient, and durable. However, with daily use and proper care, tin lining can slowly wear down and may need to be re-tinned by hand after 12-15 years.
Stainless Steel
Stainless steel is another common lining option for copper pans. It is known for its durability and ease of maintenance. Stainless steel-lined copper pans can withstand high temperatures and are resistant to scratches, corrosion, and patinas. However, stainless steel can be sticky, causing food to adhere to the surface. To mitigate this issue, stainless steel is often coated with non-stick materials like Teflon® polytetrafluoroethylene (PTFE). Stainless steel lining is also more challenging to repair or re-line compared to other options.
Nickel
Nickel is sometimes used as a lining for copper pans, although it is not as widely used as other materials due to concerns about nickel allergies. Nickel does not leach into food directly, but it can come into contact with food and cause a slight chemical reaction. Vintage copper pieces may be plated or wiped with nickel and can often be refurbished with a new coat of tin to address allergy concerns.
Silver
Silver is a newer and more luxurious option for lining copper pans. It provides excellent heat conductivity and responsiveness, with a higher melting point and even better heat conduction than copper. Silver lining can withstand very high temperatures, making it suitable for high-temperature cooking techniques. However, silver lining is very expensive and requires proper maintenance, including avoiding metal utensils and abrasive sponges. Silver-lined copper pans are typically recommended for serious chefs who require the highest thermal responsiveness and can justify the higher cost.

Copper cookware history
Copper is the oldest metal used by humans, with the earliest known copper article being a pendant that dates back to 9000 BC and was found in Asia Minor. In ancient times, copper was worked by hand with a hammer, though most copper pans are no longer made this way. Copper has been used to make tools, weapons, and bowls for thousands of years due to its low melting point and ability to harden upon being struck.
Copper cookware has been used in kitchens for thousands of years, with copper pans being an everyday essential at one point in time. Copper pans distribute heat quickly and evenly and lose heat quickly as well, making them a favourite among chefs. Copper also has 25 times the thermal conductivity of stainless steel and is five times more conductive than cast iron. Copper is also known to be the healthiest and cleanest sort of kitchenware as it is minimally processed.
Copper cookware has been popular in France for a long time, with the E. Dehillerin store in Paris being a must-see destination for cooks. Mauviel, founded in Normandy in 1830, is the big name for copper cookware in Europe. Following World War II, Chuck Williams of Williams-Sonoma stumbled into the beloved cookware shop in Paris and was enamoured by the vast array of shiny, rosy copper pots and pans. American food writer Julia Child used Dehillerin copper to cook the recipes that brought French cooking to American home cooks.
In the Victorian era, Mrs Beeton advised that "Copper pans, if used at all, should be reserved for operations performed with rapidity". However, Parisian chefs discovered the benefits of copper cookware, and copper pots continue to be used in famous kitchens such as Claridge's, where some of the copper pots were used by French chef Auguste Escoffier in the late 1890s.

Copper pan handles
Copper pans are made using two primary methods: spinning on a lathe or forming in a press. In both methods, once the copper vessel is formed, it is time to attach the handles.
The handles of copper pans are usually mounted with copper rivets. The rivets are placed through drilled holes in the handle and the pan, heated until softened, and then hammered into place. As the rivets are hammered, the metal hardens, keeping the handle in place.
Handle materials vary. While brass has gone in and out of fashion, cast iron is one of the most common and traditional choices. Some copper pans may also feature hammer marks, which were once a sign that the pan was hammered by hand but now are usually decorative.
In ancient times, copper pans were crafted by hand with a hammer, but this method is rarely used today due to its labour-intensive nature. However, some artisans still take pride in using this traditional technique. Additionally, in the past, coppersmiths had to work with small pieces of copper, which meant that larger kitchenware items required braising or riveting several sheets of copper together.

Copper pan uses and temperature control
Copper pans are highly responsive to temperature changes, heating up and cooling down quickly. This makes them ideal for cooking foods that require precise temperature control, such as candies, chocolates, delicate proteins like fish, and sauces. Copper pans are also commonly used for making casseroles or roasts in the oven.
Due to its reactivity, copper cookware is usually lined with a non-reactive metal such as nickel, tin, or stainless steel to prevent a metallic flavour from leaching into the food. Tin, in particular, is often used because it does not react to acid, making it safe for cooking foods with acidic ingredients. However, tin linings will wear off over time, and proper utensils should be used to avoid scratching the lining.
When using a copper pan for the first time, it is recommended to rinse it with warm water and pat it dry. Copper pans should be heated on a medium to high flame, as they are highly efficient at conducting heat. There is generally no need to preheat a copper pan before cooking, and a moderate heat level is sufficient. Copper pans will develop a natural non-stick coating with use, eliminating the need for additional non-stick coatings that may contain harmful chemicals.
Copper pans are relatively easy to clean and care for, despite their delicate appearance. Warm, soapy water and a soft sponge are recommended for cleaning, and copper pans should be dried with a tea towel or clean cloth and stored in a dry spot. Copper cookware can be restored to its original shine with a simple acid treatment using lemon juice or vinegar.
