Dear David,
You say....<<
Phil goes on to use this hypothesis to prove that soda firing is more
polluting to the atmosphere than salt firing.>>

Any hypothesis is just a proposition. To become a proven fact observations
have to be made and data has to be collected then analysed. A hypothesis
proves nothing.
