A classic serving tool since 1948, the Service Ideas RO128BLC Thermo-Plate Platter Set has a unique design that traps heat between the insert and polyester holder, creating a gap to insulate the food and keeping it warm until ready to serve. When butter, water or oil is added to the plate, it will sizzle letting your guests know that their food is hot and ready to eat. The Thermo-Plate is an attractive kitchen essential that you can rely on for years to come. The insert is 11-5/8" long and great for large entrees. Platter is constructed of stainless steel and rests on top of the Thermo-Plate Base.
