The heat from the heat gun will heat up the lowest-density
lowest-heat-capacity materials first... and this means the
coil form unfortunately.

For a lot of purposes working with wax, the double
boiler in the kitchen comes in handy.

But... with these god-dang polystyrene coil forms, the coil form
may begin to turn gooey below the melting point of water.

I hate polystyrene coil forms (all so popular from the HBR era)
with a vengeance. Melted way too many of them when I was
a kid.
