I couldn't decide which indicator on the pot was correct. I thought the big indicator was an arrow head and the skinny one the arrow shaft. I was, of course, wrong. Letting it heat up for 5 minutes before trying to use it at a high setting probably oxidized the tip. I'll get some of those scrubbies and see if I can't clean it up.
