“Raku”, which literally translated means “rejoicing
the day”, is a very ancient technique born in Japan in
the XVI century A.D., linked to Zen philosophy.
The decorative effect, with its metallic reflections and ”craquelè”
(the numberless small glazing cracks), together with the peculiar
working process, makes it a really exciting technique.
At first the objects are moulded using fireclay, a particular
kind of clay which resists to shocking high temperature ranges.
A first firing is carried out, in which temperatures near to
950°C are reached. Afterwards the objects are glazed and
ready for a second firing.
The peculiarity of Raku technique is in this firing method:
when the objects are white-hot they are removed from the kiln
and put into special metallic boxes, smothering them into straw
or sawdust which immediately go on fire.
Inside the closed container the smoke enhances the typical glaze
cracks and blackens the non-glazed ones. The ware, after having
lost its heat, may be pulled out and carefully cleaned from
the thin coating remaining after the second firing.
