<p>The device has a mold (730) comprising a body made of ceramic material transparent to microwaves and comprising a first recess. A coating layer i.e. enamel layer (732) comprises a ferrimagnetic material e.g. spinel nickel-zinc ferrite, covering a surface of the recess. A second mold i.e. counter mold (770), has a body made of ceramic material, comprising a second recess complementary of the first recess. A surface of the second recess comprises a coating layer i.e. cordierite layer, comprising a material including a ferrimagnetic component.</p> |
