Copper pans are loved for their quick heating and even distribution of heat. They are used for candy-making and other heat-sensitive recipes but are suitable for almost all cooking. Copper is a soft metal and a highly reactive material, so it is lined with a non-reactive metal such as nickel, tin, or stainless steel. Copper pans are expensive, and proper care must be taken to ensure they are not damaged. A common mistake is to place hot pans in the sink, which can cause thermal shock and ruin the pans. It is recommended to let pans cool down gradually on the stovetop and then speed up the cooling process by adding small amounts of tepid water.

What You'll Learn
Copper sinks are not foodsafe
Copper sinks are beautiful and unique, but they are not food-safe. Copper is a natural material that reacts to external stimuli, such as acid from food and chemicals from cleaning agents. Copper sinks are prone to developing a patina, a layer of corrosion or green film, over time with heavy use. This is a natural process that gives copper its rustic look, but it can be slowed down by using a wax periodically.
Copper is naturally antimicrobial, which is a great health benefit as it kills bacteria and prevents any film or odour from developing in the sink. However, this does not mean that copper sinks are food-safe. Acidic foods such as lemon, orange, pineapple, mustard, and coffee can damage the natural sheen of the copper and strip the patina. Therefore, it is important to avoid leaving dirty dishes and food, especially acidic foods, in the sink for extended periods.
In addition to being reactive to acids, copper is also susceptible to water spots and mineral deposits. This means that even water can cause your copper sink to turn green after a while if it’s always wet. To prevent this, it is recommended to dry the sink after each use and regularly wax it to maintain its finish.
Copper sinks are also delicate and require special care during installation and use. They are sometimes so heavy that it may be hazardous to attempt to install one yourself. Special skills and tools are required to ensure that the material does not incur any damage from extended use. For example, a sponge or scrubber can scratch the sink, so it is recommended to use only a gentle warm cloth for cleaning.
In summary, copper sinks are not food-safe due to their reactivity to acids and other chemicals, proneness to water spots and mineral deposits, and delicate nature. While they offer health benefits and a unique aesthetic, they require extra care and maintenance to look their best and function properly.

Hot pans can cause thermal shock
Copper pans are loved for being quick to warm up and for their extremely even distribution of heat. They are often specifically used in candy-making and other heat-sensitive recipes. Copper pans are one of the most expensive materials for pans, but they are a worthwhile investment for those who love to cook. They are also not too difficult to take care of.
However, hot pans should not be placed in a sink, regardless of whether it is a copper sink or not. This is because hot pans can cause thermal shock. Thermal shock occurs when there is a sudden change in temperature, such as when a hot pan is placed in cold water. The metals cool too quickly and the pan starts to pull against itself. The bigger the temperature difference, the greater the shock, but even a small amount of cold water in the bottom of your sink can cause a pan to warp, shatter, crack, or chip. Warped pans are a major problem because they won't cook evenly. They allow oil to pool on one side and they won't sit flat against an induction or electric cooktop. Even if your pan doesn't warp, the finish can come off, and the chipped enamel or nonstick coating may find its way into your food.
To avoid thermal shock, let your pans cool down gradually on the stovetop. If you need to make space, place the pan on a trivet or another heat-proof surface. You can also add a little water to the pan when it is still hot to deglaze it and pour the liquid down the sink, then wipe the pan with a towel. If you need to cool the pan more quickly, you can speed up the cooling process by adding small amounts of tepid water.

Pans may crack or shatter
While copper pans are loved for their quick heating and even distribution of heat, one must be cautious while dealing with hot pans. It is advised to not put hot pans directly in the sink, irrespective of the material. This is because a sudden change in temperature can cause thermal shock, which may ruin the pans. Metals expand as they are heated, and each of the multiple layers of metals cools and contracts at different temperatures. When a hot pan is plunged into cold water, the metals cool too quickly and the pan starts to pull against itself, causing it to warp, crack, shatter or chip. Even a small amount of cold water at the bottom of the sink can cause thermal shock. Warped pans are a major problem as they don't cook evenly, allowing oil to pool on one side. Even if the pan doesn't warp, the finish can come off, and the chipped enamel or non-stick coating may get into your food.
To avoid thermal shock, pans should be allowed to cool down gradually on the stovetop. If you need to make space, place the pan on a trivet or another heat-proof surface. You can also add a little water to the pan when it's hot to deglaze it and pour the liquid down the sink, and then wipe the pan with a towel. If you need to speed up the cooling process, you can add small amounts of tepid water.
It is important to note that while cast iron pans are less susceptible to warping, they can crack if they are heated to extremely high temperatures and then plunged into cold water. Therefore, it is always recommended to let pans cool down before placing them in the sink, regardless of the type of pan or the temperature of the water.

Pans may warp
Copper pans are loved for being quick to warm up and for their extremely even distribution of heat. They are often specifically used in candy-making and other heat-sensitive recipes. Copper is a soft metal and is highly reactive, so it is not food-safe on its own. Therefore, copper pans are lined with a non-reactive metal such as nickel, tin, or stainless steel.
When it comes to cleaning copper pans, it is important to note that copper is highly conductive, and users often have to relearn what temperatures to cook different foods at. It is recommended to use half the heat or flame that you would on a non-copper pan and never heat an empty pan. For example, if you cook eggs on medium-high heat in a stainless steel skillet, you should use medium-low heat for a copper pan. This is to avoid burning the food and melting the tin lining, as tin is also a soft metal that melts at around 450°F.
Now, coming to the issue of putting hot pans in the sink, it is generally advised to avoid doing so, regardless of the type of pan. Placing a hot pan directly into a sink full of water can cause thermal shock, which can lead to warping, shattering, cracking, or chipping. The problem arises when there is a sudden change in temperature, as the metals cool too quickly and the pan starts to pull against itself. Even a small amount of cold water at the bottom of the sink can cause the pan to warp. Warped pans are a significant issue because they won't cook evenly, allowing oil to pool on one side and affecting their stability on induction or electric cooktops.
To avoid warping your copper pans, let them cool down gradually on the stovetop before placing them in the sink. If you need to make space, you can put the pan on a trivet or another heat-proof surface. You can also speed up the cooling process by adding small amounts of tepid water to the pan after it has cooled briefly. Additionally, when washing your copper pans, avoid using extremely hot water and always use the soft side of the sponge to prevent scratching the soft, thin layers of metal.

Pans should cool on the stovetop
While it may be tempting to put hot pans in the sink to free up space on the stovetop, it is not advisable to do so. Placing hot pans directly into a sink full of water can cause thermal shock, which can ruin your pans, even the expensive ones. This is because the sudden change in temperature causes the metal to cool too quickly, and the pan starts to pull against itself. The bigger the temperature difference, the greater the shock. Even a small amount of cold water at the bottom of the sink can cause a pan to warp, shatter, crack, or chip. Warped pans are a major problem as they won't cook evenly. They allow oil to pool on one side and won't sit flat on an induction or electric cooktop.
To avoid this, let your pans cool down gradually on the stovetop. If you need to make space, place the pan on a trivet or another heat-proof surface. You can also speed up the cooling process by adding small amounts of tepid water to the pan. If you deglaze the pan with a small amount of water while it's still hot, you can easily wipe it down with a towel and avoid food residue sticking to it.
Cast iron pans, in particular, should never be washed with soap or detergent/soap as it is a degreaser and will strip the oil off. Instead, wash them with hot water, dry them, and lightly oil them before using them again.
Therefore, to ensure the longevity of your pans and avoid any warping or damage, it is best to let them cool on the stovetop before placing them in the sink or washing them.
