'''Sulfur dioxide''' is a colorless gas with a pungent smell.

== Uses ==
Used in the sulfite process for making wood pulp to be used in [[paper]] production.

== Production ==
'''Sulfur dioxide''' can be found naturally from volcanic activity.

Modern and early production of '''sulfur dioxide''' comes from [[Iron pyrite|pyrite]] roasting, a process in which you would crush the [[Iron pyrite|pyrite]] to reduce the surface area using a mill or hammer. Next you roast the pyrite in a [[Furnace|brick furnace]] or simple smelter at temperatures of '''500–700°C'''. [[Iron pyrite|Pyrite]] is placed on trays within the heating apparatus as [[oxygen]] is allowed to flow through or over the hot [[Iron pyrite|pyrite]]. As it heats, the sulfur in the pyrite oxidizes and is released as '''sulfur dioxide''' gas. This also produces [[iron oxide]] as a waste product. The '''sulfur dioxide''' would then be redirected using a brick or metal channel into another chamber for collection. Allowing the '''Sulfur dioxide''' to pass through water allows for the production of sulfurous acid.
