Furnace fragments and tapping slag at KAJ are smaller than in most excavated contexts at KEN, and the tuyere
are shorter and less sophisticated (Levy et al.
The 42-day reline began with the blowdown of the furnace, followed by the removal of blowpipes and tuyeres
While the main activities carried out here were the re-melting of copper and slag crushing, many artefacts came to light including hammerstones, dimpled hammerstones, pestles, polishing stones, grinding stones, tuyere
pipe fragments, partially processed copper, copper ore, and slag with copper.

In addition to straight, cylindrical tuyeres
, we also uncovered an `elbow' tuyere
and four double tuyeres
(previously unknown on Cyprus) (FIGURE 4).
Along with the tools, large quantities of iron and copper slag (see TABLE 2), charcoal, ash, burned earth, hammer scale, iron nails, animal bones and horn cores, and a clay tuyere
, were recovered from deposits up to 1 m thick beginning about 0.

For example, cupola operators can keep a safety tuyere
open to collect any molten metal that escapes in the event of a runout.
If the tuyeres
through which air is injected into the furnace melt down to a point where the molten metal threatens to flow into the air cavity, the first and second helpers mend the nozzle by covering and stoppering it with clay.
Improuved slag formation in the blast furnace by co- injection of basic fluxes, together with pulverized coal, through the tuyeres
It has 36 tuyeres
(pipes) which allow air to be blown into the furnace and four tap holes for removing the iron out of the furnace.
