French chefs have long known about the superior conductivity and performance of copper cookware. But is it really a proven fact that copper cookware actually heat and cook better compared to other metals such as alloys, stainless steel and cast iron?
In this guide, we dive deep into the science of copper conductivity and how it makes for a superior, long lasting cookware.
Copper Heat Conductivity: Why It Makes Pure Copper Cookware Superior
In order to look at copper and its heat conductivity, we can look at its thermal conductivity compared to other metals. Please note that this applies to real copper cookware ONLY and not copper-plated ones.
Pure copper has one the highest thermal conductivity of approximately 385 W/m.K at room temperature. Right behind silver(406 W/m.K), copper's superior heat conductivity makes it an excellent candidate as home cookware, water heater, cooling pipes and computer heat sinks. Adding other types of metal to copper such as brass or tin does lower its heat conductivity significantly.
Our copper cookware such as our Copper Skillets have a 2mm thickness to take advantage of copper's already amazing heat conductivity by improving heat transfer. This means even on low or medium heat on a compatible stovetop, our handmade copper cookware gives you excellent cooking results.
Another great advantage due to the even cooking performance of copper cookware is the absence of hot spots. This means whenever you are making things like sauces, jams or even baking bread in our Copper Dutch Oven, you won't find any burnt food residue as the excellent heat transfer is spread across evenly.
In the long run, cooking on low heat regularly not only reduces your gas or electricity bill, this is also one of the reasons why our copper cookware is heirloom quality and long-lasting. Unlike conventional store-bought non-stick cookware which are unsafe for long-term use due to the shedding of harmful non-stick coating, you can rest assured that Sertodo Copper's pure copper cookware is great to cook with, naturally non-stick and a family heirloom that makes a great wedding and housewarming gift for the next generation.
Other Copper Cookware Advantages
1. Egg White Stability: Sertodo Copper Mixing Bowls
One of the most fascinating benefits of copper cookware isn't on the stovetop at all—it's in the mixing bowl. When egg whites are whisked in a copper bowl, tiny amounts of copper ions react with conalbumin (also known as ovotransferrin), one of the proteins naturally found in egg whites. This reaction forms a stable complex that helps strengthen the protein network as air is incorporated, making the foam more stable and less likely to collapse or become over-whipped.
The result is egg whites that whip up more easily into glossy, stiff peaks with exceptional stability, making copper mixing bowls a favourite among professional bakers and pastry chefs.
This added stability is especially valuable when preparing delicate recipes such as meringues, soufflés, angel food cakes, and macarons, where a strong, airy foam is essential for achieving the perfect texture and rise. While stainless steel and glass bowls can also produce excellent results, copper provides a natural chemical advantage that has made it the traditional choice for whipping egg whites for centuries.
2. Even cooking performance: Copper Jam Pans and Petite Copper Butter Pot
Another unfair advantage from copper cookware's heat conductivity is the lack of hot spots, which also translates to even cooking performance. This quality makes copper cookware great for cooking sauces such as Hollandaise and red wine reductions, delicate fruit jams as well as omelettes that would benefit from instant heat responsiveness.
3. Stunning display and great for slow cooking: Copper Stock Pots and Alicante Copper Paella Pan
Whether you are catering a party or event last-minute, or looking for an easy way to entertain guests without spending more on presentation, choosing our beautiful pure copper cookware is a great investment!
With our hand hammered Copper Stock Pots and Copper Paella Pan, you can have delicious food ready in a few hours and also effortlessly wow your guests with the gorgeous copper presentation.
