Nice work! Cast iron truly is the opposite of planned obsolescence.
There’s a reason they started selling pans where a single scratch makes people replace them…
A lodge would last a century, probably longer unless you stored it in salt water.
Ironically the only reason Lodge can be as big as they are today, is most people don’t have a cast iron pan.
I got a big one and a small one. They’re awesome and highly recommended, but I’ll never ever need to buy from that company again now.
