β¦ Synopsis
The Superphosphate Fertilizer, to be referred to simply as fertilizer, was used to impregnate some tropical timbers. It was observed that this treatment drastically altered the thermal characteristics of these materials. The results are interpreted as arising from the fact that on heating, fertilizer evolves molecules that interfere with the chemistry of pyrolysis/combustion of wood cellulose.
