The ornamental design for a ceramming furnace, as shown and described.

FIG. 1 is a front elevational view of a ceramming furnace, showing a new design;

FIG. 2 is a top plan view thereof;

FIG. 3 is a side elevational view thereof;

FIG. 4 is a rear elevational view thereof.

It will be understood that the perforated panels and portions may have strengthening ribs, operating components and instructional tags and the like in their field of view without destroying the overall effect of the new design of the present invention. Also, addition of additional display lights and a different arraying thereof would not destroy the overall effect of the new design if the general overall new design of the present invention is adhered to. It will be understood that written indicia would be expected to be present, for example, next to each display light, identifying what it was indicating.

The patterns of perforations which are fragmentarily shown in all views are understood to repeat uniformly and continuously across the areas of the ceramming furnace.

Webb, Ronald C.
