The pots are perfect for kettles. This is 3/4 inch but I also used 1/2" for saucepans. They are so nice and shiny! I haven't shown it, but I painted the inside of the pot with silver nail polish. It takes on the look of tinning; it keeps the copper from tainting the food. I used from 2 to 4 coats of nail enamel to build up the color. Below is one of the polishes I used.
