Chemex Stainless Steel Grid,
Verified Purchase(What's this?)
This review is from: Chemex Stainless Steel Wire Grid for Use on Electric Stove, 6.5 Inch (Home)
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.
