An enhanced electric oven (10) comprising an oven-body (12) and a vault or dome (14) which externally enclose an oven cavity or cooking cavity (17), a flue (16) for fume exhaust, a mouth (18) for accessing the oven cavity (17), closable by way of a door (20), a dish supporting plane (22) placed outside the mouth (18), a hood (23), if any, a lower heating plate (33), and an upper heating plate (33A) which accommodate electric resistors, a modular and removable cooking plane (34) made from a refractory material, and means for controlling and distributing heat flow within the oven.

A replacement product for a portion of a castable refractory surface contains a precast refractory piece with accommodation for an adjustable positioning structure for conforming the working surface of the precast refractory piece to the castable refractory surface. A process for installing the precast refractory piece includes positioning the precast refractory piece with respect to the castable refractory surface, and introducing castable material into an interface volume between the precast refractory piece and the castable refractory surface.
