text: The combustion is likely to have been carried out in a sealed vessel and the "fact" that ammonium carbonate, hydrogen sulphide, hydrogen, methane and water was produced, all of which contain hydrogen atoms, suggests several possibilities: the gunpowder was fired in the vessel in air containing moisture (source of hydrogen for the hydrogen sulphide, the ammonium carbonate, the hydrogen, the methane and the moisture), the charcoal was not fully carbonised and contained some residual hydrocarbons (or, more more likely, contained moisture).
