spring follow a m long channel to the head
of the travertine ridge and fall into the travertine
terraces, approximately 7 meters long, where
the deposits form.
At the source, the temperature of thermal water
is .C, and it contains a high concentration of
calcium carbonate. When it comes in contact with
the oxygen in the air it forms carbon dioxide and
carbon monoxide gases, which evaporate and leave
deposits of calcium carbonate. nitially, the calcium
carbonate deposits are like soft jelly. ver the
time it hardens and forms the travertine. However,
if visitors are allowed to walk in the cascading
pools, that leads to squashing and dispersing the
soft jelly of calcium carbonate. At present, thermal
water is released over the travertine in a controlled
programme. f a large amount of water is allowed
to ow on a certain area for a long time it leads to
moss formation and darkening of the colour
of the travertine. The atmospheric
conditions, temperature loss
and duration of the ow
affect the creation and
maintenance of pure
whiteness.
