I moved into a new flat and it comes with a brand-new induction glass top stove. Unfortunately, it seems like the glass rather easily scratches: There is already a visible scratch in it (likely caused by me, but I have no idea what caused it). This is why I don't want to put my Lodge cast iron skillet (with a rough bottom) directly on it. I've found several pages stating that I can easily prevent scratches by putting something between the cast iron skillet and the glass top, such as paper towels, newspaper or parchment paper, as long as I'm not going for a very high heat sear.
However, that is mostly the purpose of my cast iron skillet: To sear meat at very high temperature.
Has anyone used any of the above objects successfully as a protective layer between cast iron skillet and induction glass top, while searing at very high temperature? Or is some other sort of layer even more preferable?
