That may work - but if not controlled might get smelly.

I did try a few more of these tests and found that there are several types of artificial corks. The one I used in my report is made from a homogenous formed material and these work better.

Some other corks have an outer layer of denser plastic that actually bubbles up when heated too much, plus the deformation is not uniform between the outer layer and softer core.

I'm going to try another method of deformation by pressing the preheated cork into a rigid cone of suitable profile..............
