I avoid glass top ranges for that very reason.The Lodge Factory is only 44 miles from Chattanooga so you can buy it almost every where. From grocery store to Walmart. Cast iron does not work great on a glass cooktop. I have Mom’s old iron skillets but only make cornbread in one of them.
Electric is fine, but glass top ranges are a non starter for us.
Most of my extensive cast iron arsenal is close to 100 years old, and some of it gets used almost every meal.
