The siltcast tile
making seminar is a part of the monthly workshop program we
have been conducting since 1970 at Arcosanti. One-day to one-week
intensive Siltcast programs are also offered for those
crafts-oriented. [T]


Randall Schultz,
Siltcast coordinator, gives instructions to the participants who are
about to have “hands-on” experience. [T]


Students prepare the
silt by sifting and adding some moisture to give the right consistency
for the medium to work. [T]


The silt is placed
in the form, impressed and painted. Then, the plaster is cast on the
designed silt bed. Later the silt is washed away when the plaster
hardens and the reversed patterns appear on the finished tile surface.
The whole process takes only a few hours. [T]
