T304 stainless steel. Encapsulated bases. Mixing bowls work as dome covers and as double boilers. The other covers have a unique thermometer to help regulate cooking temperature.
You can stack cook with this set.
This set has lids that seal against the saucepans with a vertical lid lip. This is typical of all cookware sets, however this is not true "waterless cooking". One aspect of a waterless cooking set is that the lids must have a horizontal mating surface with the pan. That surface must be a minimum of 1/4" wide.
The sets that qualify as such are the KT915, KT17, and KT17Ultra. They are heavy duty, will last a lifetime, and we discount them hundreds of dollars below the folks selling them at the fair grounds, door to door, etc. We are discounters and maintain one of the lowest prices on the internet for top quality cookware sets.
