Abstract
A method for making a non-stick ceramic cooking vessel for a slow-cooker, the vessel having glazing defining a seal over a cooking surface of the ceramic vessel, the method comprising the steps of removing at least a portion of the glazing while preferably maintaining at least a portion of the seal of the vessel and applying a non-stick coating over the cooking surface. The step of removing the glazing is preferably achieved by grit-blasting at least a portion of the glazing with aluminum oxide. Additionally, the cooking surface preferably includes a bottom surface and a wall surface wherein the glazing is preferably removed from the bottom surface such that the seal is substantially removed, and a portion of the glazing is preferably removed from the wall surface such that the seal there remains substantially intact. The method preferably also includes the steps of applying a first layer of a non-stick coating over the cooking surface, drying the first layer, cooling the first layer and applying a second layer of a non-stick coating over the first layer. Additionally, the method preferably includes the steps of applying a third layer of non-stick coating over the first and second layers, drying the second and third layers, and curing the layers of non-stick coating.
