Abstract
The cooking vessel has a laminated wall including one layer of a magnetic material having a thickness, determined in accordance with skin depth as a function of the operating frequencies of the cooking device so that the major part of the power is developed in the one layer and substantial penetration of the magnetic field produced by the device beyond the layer is prevented, and another layer of relatively high thermal conductivity material which promotes the uniform distribution of heat derived from the magnetic layer throughout the other layer.
