In fact, the Catalan method, properly so called, requires the construction of kilns and crucibles, in which the ore and the coal, placed in alternate layers, are transformed and reduced, But Cyrus Harding intended to economize these constructions, and wished simply to form, with the ore and the coal, a cubic mass, to the center of which he would direct the wind from his bellows.
En effet, la méthode catalane proprement dite exige la construction de fours et de creusets, dans lesquels le minerai et le charbon, placés par couches alternatives, se transforment et se réduisent. Mais Cyrus Smith prétendait économiser ces constructions, et voulait former tout simplement, avec le minerai et le charbon, une masse cubique au centre de laquelle il dirigerait le vent de son soufflet.
