Abstract
Using mass spectroscopy, an analysis of gas evolved from samples of green sand heated in a vacuum was shown to comprise water steam with traces of carbon oxides. Seacoal added to the sand results in the evolution of carbon oxides and hydrocarbons. The hydrocarbons disappear at a temperature below 600 degrees C, so they cannot reach the metal/mould interface and influence the atmosphere in the mould cavity. In the sand sample heated to 800 degrees C, plates of lustrous carbon were found. They are formed as a product of the decomposition of hydrocarbons.
