e the critical temperature has been reached.
Typically, organic thermoplastic materials or binders will change in the 140 to 240F (60 to 116C) temperature range. Thermosetting organic materials or binders will start to deteriorate above 350F (177C). Hydrated inorganic binders such as clays, portland and lumnite cements, gypsum, sodium silicates, oxysulfates, and oxychlorides will lose varying amounts of water of crystallization at temperatures from 250 to 900F (121 to 482C) dependent on the comp
