Notes: 17)

This technique is documented and favoured by
the Greek painter Andreas Fokas. He made coloured
wax sticks, constructed a heated palette of metal,
and painted portraits from life which come very
close to the Fayum portraits. The painter G. Mavroides
used a double-boiler to keep the metal palette warm
over boiling water, thus maintaining a constant 
emperature and preventing the pigments from
darkening through excessive heating. Both artists
generously shared their knowledge with me in
great detail.
