This 7 inch square of heat resistant silicone from SiliconeZone is safe up to 675 degrees F and is flexible enough to be used as a pot holder. Alternatively, set it on your table and use it as a trivet - it won't slip or skid like cork, metal, or coth. The pot holder has a raised grid on the surface for excellent gripping and does double duty as a jar opener. This Grid Pot Holder is truly a multi-purpose kitchen tool and best of all, cleaning it is easy - it's dishwasher safe. Yellow.
