I accidentally bought a set of induction vessels. Currently I have a gas cooking range. Can induction vessels be used on a regular gas stove or electric stove?
Induction cookware is only that which has enough steel or iron in it to have a magnet stick to it. As was mentioned in the comment, it is usually the other way around. Stainless steel and cast iron are great for cooking on most any type stove top... Or a grill or a campfire! They are the epitome of versatility.
