It takes two weekdays to transform 10-15 tube bends into
an artistically shaped piece of plastic. A mould is used
to align the segments. They are then mounted vertically on
a pedestal and seal-welded. Once the seams have been
removed, they are longitudinally and evenly ground. A clear
varnish is applied to give it a polished finish and to optimise
the heating capacity.
