Default Re: Destruction of the E-coal

Seems like the ceramic disk is the resistor due to oxides in the ceramic. Similar to large ceramic resistors. the metal coated discs is the heatsinks that does the heat transference to the bottom of the coal. Looks like there was two ceramic heating elements and the metal disks looks like aluminum coated with a heat conducting paste for high heat transference.
