    Hi,First of all, thank you for your reply. It did not make the job. could not achieve an even heat on all the plaster mold. End up trashing everything as the heat gun heat up fast and bad on the front-face of the mold.As you advice I did put the mold on a metal can. My mold is about 8cm X 8cm X 10cm.I know now that I should point the hot air gun to the metal can and not directly to the mold.
