Chemex Wire Grid Heat Diffuser for Glass Coffee Makers, Kettles, Cookware

Very glad we got this wire grid. I started using it right away. My Chemex is quite old, had switched to the automatic coffee makers with plastic. Now switching back! Am now trying to get away from plastic totally. It's not that easy. Remember when "they" had put melamine in cat food to raise the protein level? So many cats died. Mine was pretty sick, stayed sick, don't know if it was from the melamine but either way, other pets were actually dying. It was not listed, was a contaminant. So, it's a journey, to try using mostly glass and stainless steel. This wire grid, I put on burner that is very low, and it's great to keep the coffee warm, esp for 2nd cup! Definitely recommended.

I had been using a clover heat diffuser that came with my glass kettle on a glass top magnetic inudctance heating top. The clover didnt reach the edges of the circle heating element so it would constantly turn on and off. This thing just barely covers to the edges of my heating element in 4 spots and the stove has a much more consistent heating mode of action now. It is also perfectly flat and very sturdy. Its probably 4-5 times thicker than your average clover heat diffuser. Although whatever is coating this diffuser has turned from a pale gray to a somewhat shiney brass color after using it daily for a month. It doesnt affect my heating, but its just something to note.

I use this Stainless Steel Grid for a Medelco glass kettle, not a Chemex, but the idea is the same. Compared to the little cloverleaf type of heat spreader, it's a lot more stable -- my kettle doesn't slip to the side if I don't place it square in the middle the way it did with the cloverleaf. Compared to the cloverleaf, it's a little thicker, so you may need to use slightly higher heat than with a cloverleaf. It has not turned dark the way my cloverleaf heat spreader did, and is still shiny silver colored after a month of use.

I wish it laid flat!

This is great! So glad I bought it. Now I can have hot coffee all Saturday morning without having to reheat my mug nor worry about breaking the glass. I bought a Chemex thinking I can reheat coffee but didn't realize I couldn't with my stovetop. Now I make my coffee, turn the stove on low, and just leave the Chemex on the stove. Hint - just leave the coffee filter on top of the Chemex while you reheat - it prevents evaporation!! I did that accidentally, came back, and was like cool.

I have a glasstop stove and this product is great for use with glass cookware. I always store leftovers in pyrex glass containers, and this steel grid saves me from tranferring the food to a stainless steel sauce pan, or having to heat the whole oven! I just put the grid underneath the pyrex container and reheat the food. It's excellent! I've also started using it with my regular stainless steel sauce pans to heat milk - nothing sticks at the bottom! The possibilities are endless...The wire itself is heavy duty and not easy to bend, so it's sturdy and stays flat.

I have a really pretty teakettle made of glass that is meant to be used over a gas range. This coil allows me to use my teakettle over a range with metal coils without damage. It is a remarkably simple product made of stainless steel wire and provides a small amount of separation between the glass and the hot metal coil and prevents the intense heat from damaging the glass. This is a must if you have stovetop glassware and an electric range. With this, I can now boil water in my glass teakettle in my stove. It's very nice.

Called Chemex before buying this and they say high heat on electric coil stove was fine and that it would not damage my just purchased, and not cheap Chemex kettle.Initially set it to boil a full 64 ounces at 9/10 and worked great so I'm going to 10 next time as it takes a full 15 minutes to boil the contents on 9!You can of course use these to keep your Chemex coffee pots warm too but I haven't tried that.
