Cook King is made by Wargo, a family firm in Międzyrzecz in western Poland that's been cutting, forming and welding steel garden equipment for over 27 years. Everything they sell is made in the same workshop.
The material is the point. Cook King works in raw, uncoated steel. There's no paint and no powder coat on the bowls, which is why you can run them at fire temperatures without anything degrading, and why they weather to a deep brown instead of peeling.
The construction follows the same thinking. Legs, rims and handles are welded, not bolted, so there are no fixings to work loose after a hundred heat cycles and no seams to open as the steel expands.
The finish isn't perfect, and they'll tell you so themselves. Hand welded steel shows small differences in shade and surface, and two bowls from the same batch won't be identical. That's the difference between something made and something stamped.
Cook King states its steel is approved for contact with food. That's their claim and we pass it on as theirs; if you need the paperwork for a commercial kitchen, ask and we'll request it.
