A continuous oven for firing ceramic objects, e.g. rods, tubes &c. comprises a heating element 2 surrounded by insulation 1, a rotary carrier element 3 for the treated object 4, said carrier element being longer than and extending through said heating element, and a roller 5 forming part of mechanism for rotating the carrier and moving it axially. In a modification (Fig. 2), the carrier has several peripheral compartments for the objects and a central bore containing a heating element. Another embodiment (Fig. 4) has a rotatable carrier over which objects are slipped. A final embodiment (Fig. 5) shows a similar oven to that of Fig. 1 in perspective.
