When it comes to copper cookware, thickness matters. Generally speaking, the thicker the better when it comes to copper cookware; however, there is a lot of debate about what exactly constitutes “the best” thickness. Copper is an excellent conductor of heat and can be found in various forms ranging from thin sheeting all the way up to heavy gauge pots and pans. The thicker varieties are usually made with multiple layers of copper bonded together and offer superior conduction as well as durability. Thicker pots and pans also tend not to warp or dent easily so they will last longer than thinner options. On the downside, thicker pieces may weigh more than their thinner counterparts which could make them more difficult to maneuver while cooking. Ultimately, when deciding on what thickness is best for your particular needs it's important that you consider how often you plan on using your cookware as well as how much weight you're willing to lift in order to achieve optimal results!
