Potassium aluminium sulfate, hereafter referred to as alum, was used as a flame retardant for some Nigerian timbers. It was observed that flame spread rate and after‐glow time were drastically reduced. Thermogravimetric analysis shows that alum functions as a flame retardant (FR) by a complex process that entails the dehydration, condensed phase, and the vapor phase mechanisms.
