Works great. Much better than cheaper metal ones I have had in the past.
Useful and unique

I love this diffuser. Years ago I used a star-shaped wire under my pots and pans to slow down the heat. This wire had been my grandmother's and it worked ok. But this BellaCopper is wonderful. I use it almost every day. It's pretty ugly now but that's ok. It does its job and I hide it away for tomorrow.

Takes a little time to warm up but works great on large pots and pans. I usually use a 14 inch fry pan and this get the heat all the way to the edges.
Nothing like I thought it would be

I used it once on my electric stove and it turned black, not a nice patina, Even after using bar keepers to clean it. Also it actually made hot spots on my pan and discolored the burner pan. I'm returning it.
FINALLY ... evenly distributed heat!!

Have a professional gas cooktop & hot spots keep me struggling w/perfect evenly distributed heat. A particular problem when making pralines, so decided to try it. OMG!!! It's fabulous!! Bought the 8 inch one. Just browned meat in a 12 in pan and total heat distribution accomplished (and with the Frywall - no splatters!) Think I'll invest in more for several other burners. After first firing it discolored, but that's characteristic of 100% copper. Appreciate that these are THICK copper, too. The BEST invention ever!! Well ... a tossup when compared to the silicone Frywalls you all sell. Keep the kitchen inventions coming!!

High performance solid copper heat diffusers and defroster plates. Copper is a superb conductor of heat. Not only does copper evenly distribute heat, its greater mass allows it to hold more heat.


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? more Their Story
