Tea kettle question
Why do tea kettle instructions tell you to NEVER use it on high heat? I just bought a new Copco brushed stainelss steel tea kettle to use on my Kenmore Induction cooktop. It works great, unlike the Chantal enameled teapot that not only whistled with irregularity but the enamel began chipping off both inside and outside.
This is not the first time I've bought a tea kettle with those instructions (which I have usually ignored). But what I want to know is WHY not use high heat.
