| This ensures that the laden fluid is evenly distributed around the casing and therefore enters the tuyeres from all directions. |
| Artifacts discovered here included potsherds, some tuyeres, a clay smoking-pipe, oval-shaped pieces of chalk, shells of a variety of saltwater shellfish, and mammalian bones. |
| The tuyeres are used to implement a hot blast, which is used to increase the efficiency of the blast furnace. |
| It was also necessary to devise new methods of connecting the blast pipes to the tuyeres, as leather could not longer be used. |
| In particular, tuyeres in the furnace became blocked with slag. |
| The 42-day reline began with the blowdown of the furnace, followed by the removal of blowpipes and tuyeres. |
