"The purpose of this Thesis is to try to show the effect which certain variables, which are always present in practice, have upon the condensation of Zinc Vapors to Metallic Zinc. That these variables can and do play an important part in the Zinc Smelting Industry can be shown from the fact that all of the zinc obtained at the present time is won from ores by reducing the oxide of zinc to metallic zinc by means of carbon. This operation necessarily takes place at a temperature above the boiling point of zinc. This means that the zinc immediately on being reduced forms a vapor and must be condensed from this gaseous condition in order to be recovered. this condensation would be governed by the same laws which control the condensation of other gases to their liquid form" – Purpose, p. 2.
