Better cooking!

Works well! My sloppy joes cooked- no sticking to the bottom of the pan!


Great kitchen gadget!

I've always had trouble with my gas cooktop on the lowest setting, being too hot for a good slow simmer. This little plate works great. I haven't had an opportunity to use it for defrosting, but I think maybe the larger size would be better for that. But to evenly distribute a low heat-this is perfect!More > < Less

Worth every (copper) penny!

We have a super-fancy new range in our remodeled kitchen that has a stovetop with flames that are shaped in a star pattern to diffuse the heat. So heat diffusion isn't our issue. Our problem is that even on low heat, the flames come to the edge of the burner and make pot handles on smaller saucepans REALLY hot. This diffuser solves that by blocking the flames from reaching up to the handles. Given how pricey our range was, the price we paid for this copper diffuser was a drop in the bucket to solve the problem. The powder cleaner that comes with it works great, so I bought more at the store so I can keep this looking great on top of my stove.More > < Less

best thing for a gas stove that tends to heat pots unevenly. Use it all the time.

About BellaCopper

Cooking Assist

Copper cookware is prized by kitchen connoisseurs for its unsurpassed ability to distribute heat quickly and evenly. But it’s an expensive metal, and copper pots and pans are an investment that many of us can’t quite justify. Thanks to Pete Mohler, there’s an affordable way to tap the conductive properties of copper without buying expensive new cookware.

Pete, who’s an aerospace engineer, came up with the idea for a copper heat diffuser when he wanted to improve the performance of a mediocre stove. He designed a solid copper plate that fits on top of a stove’s burner, under any ordinary aluminum, iron or stainless steel pan. The copper plate distributes heat evenly across the entire cooking surface of the pan, so foods cook more evenly and with less scorching and scalding. Pete teamed with Bill Hackman, and the two launched BellaCopper to commercialize the idea.

BellaCopper’s hand-finished heat diffusers come in different sizes for maximum versatility. You can use two diffusers side by side to turn two adjacent burners into a single griddle-sized heat source, for example. You can use them as hot plates to keep food warm, or in the oven to maintain a more constant baking temperature. BellaCopper’s heat diffusers also double as defroster plates: If you place two frozen chicken breasts on a room-temperature copper plate, they’ll defrost in about 40 minutes as the internal heat from the plate is transferred to the frozen food.

Who knew a simple copper plate could be so useful in the kitchen?
