The construction of the bottle kiln was largely replicated in the later forms of batch-process static kiln. The base and the conical section were built from ordinary bricks and mortar (although concrete was occasionally used). Iron hoops around the outside of both the base and the cone provided tensile strength and allowing thinner brickwork.

DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.
