We attempted to faithfully replicate His’s protocol. His reports that he dripped sizzling wax onto the tissues although they have been mounted on the gutta-percha plate. Having said that, he offers several facts. We presume that he made use of gutta-percha mainly because its small thermal conductivity [28] intended that the wax could stay molten for a long time just before cooling and solidifying. Since we had been not able to acquire a plate of gutta-percha, we made use of plates crafted from Bakelite or cork, the two of which have very low thermal conductivity [10, 23].
