The production of dental rubber for the manufacture of plates for dentures was a success after much experimentation. A fire extinguisher was converted into a still to produce rubber oil from rubber scrap. Dental rubber was treated with this oil to make it pliable. This process can be seen on the above painting, as well as a ‘before and after’ snap shot of a POW without teeth and then with dentures after some manipulation in the dentist chair.
