Unfortunately, when purchasing from a catalog or off the internet, the pictures don't usually show the bottom of the pans. This means shopping in person for cookware for me.

Cooking on a smoothtop range has made me very cautious when purchasing any pot or pan. It must have a flat bottom. I have some cast iron skillets that I have owned for years and they have flat bottoms. I recently purchased a cast iron stew type pot with a handle and lid and it has a flat bottom. I ran my hand across all of them on the shelf to find the smoothest bottom and to make sure there are no carbon bumps that could scratch my cooktop.

Were you given any clue that the raised emblem would be on the pan? 1/4" is really very high. I have never seen any pan with that high an emblem. Given the weight of a cast iron pan, I would ask them to pay the return postage charges if you choose to return it.
