If you click on the link below you will see some information about Vollrath cookware... https://kitchenfold.com/cookware/vollrath-cookware-review/ This pot is made of an alloy that contains some aluminum so the pot heats quickly. But it's so heavy duty...has such a thick base that ingredients do not burn! I used this pot for more than 10 years in my commercial business...sautéing veggies and meats to perfection! I also used it in the oven, baking three and four chickens at a time! It's just so nice to have such a WIDE pot! It's in amazing condition! 14" opening. 6" high. Email me and get cooking! Or, call me...
