The oven chamber (12) has guides (14 - 19) at the sides to receive at least one heated partition (22) made from a substrate, especially a base, with an external layer of direct heating conductors covered by an insulating layer. The partition also has contacts (42, 43) to make electrical contact with others (20, 21) on the guides. The oven chamber (12) has guides (14 - 19) at the sides to receive at least one heated partition (22) made from a substrate, especially a base, with an external layer of direct heating conductors covered by an insulating layer. The partition also has contacts (42, 43) to make electrical contact with others (20, 21) on the guides; it is made from glass, especially borosilicate glass, or a vitro ceramic material. The heating conductors are applied by vacuum deposition or pyrolysis projection, using an alloy based on NiCr, FeCr or an oxide such as tin oxide doped with Ce, La, Sb or Zn.
