Copper Coffee Pot

Copper Coffee Pot
where can I find heat defuser plate for coffee pot?

Five years ago I bought a brass/copper round,thin plate to put under the carafe of an automatic coffee maker. It keeps the coffee from over cooking while it sits on the coffee makers warming plate. It works great and I want to buy some for friends; I cannot remember where I bought it and have tried every kind of store and on the web without success. Anyone know where I could find this?

have u tried sur la table or jb prince in new york (jbprince.com). my mom use to do the same thing, but i believe she brought hers in chinatown (San Francisco). she also used it on her gas stove to keep a pot of rice warm and to keep it from burning.
