Field Reports from the
end of the 1999 Field Season
CONSERVATOR'S REPORT

Mina Gregory, Andrew Fearon
Report 4: July 23

Mina Gregory consolidates
a new bronze find.
As the progress of the excavation continues,
a steady and increasingly full stream of objects passes through
the doors of the Casa di Giotto conservation lab. We are just
entering the phase towards the end of the dig when we begin to
develop an accumulation of finds and must prioritize treatments
based on needs of stabilization, identification, and importance
to the archeological process. Fortunately, the objects not completely
treated from last season seemed to fare the year quite well,
so if full treatment of all objects is not possible before the
end of the season, it will be possible to stabilize them for
treatment next season.

Andrew Fearon cleans a stamped
bucchero sherd.
Among the many new finds that are presently
being treated are a number of interesting copper alloy objects,
including a coin excavated from Trench 15 that appears to be
of Roman date. The coin appears to have the image of a rooster
on one side and the profile of a human face and helmet on the
reverse. From Trench 14, a decorated copper alloy bead was cleaned,
revealing an excellent state of preservation. Also from Trench
14 this week is a copper alloy stud with traces of a ferrous
shank similar to two other studs excavated last season; one from
Trench 1 and the other from Trench 8 which is embedded in a relatively
well preserved piece of carbonized wood. All three of the studs
are nearly identically in size and in good condition. As with
the earlier two, the preferential corrosion of the iron on the
stud from Trench 14 has left the copper alloy portion well-preserved.
The remaining copper alloy currently under treatment ranges from
the simple rounded slag to a finely articulated shell design
fragment.

After anxiously awaiting the opportunity
all season, the conservators were called up on site to carry
out on-site conservation. Several fragile copper alloy objects
were removed from trenches at the main site and we were also
called on site to help lift two fineware bowls from Trench PF
2 because of their orientation and possible completeness. As
previously discussed, the ceramics in this area quite consistently
lose their surfaces during the course of excavation due to the
soft and fragile nature of the ceramic and the hard clay consistency
of the soil. Several techniques were tried during the course
of removing these bowls to maintain the original surface, however
none were entirely successful. Although the two bowls were removed
with no excavation damage, a root system from nearby vegetation
had already infiltrated the ceramic fabric, damaging the original
surface. Further work is to be done in the hopes of devising
a way to retain the original surfaces when possible for these
ceramics coming out of Podere di Funghi.
In addition to the aforementioned activities
in the field, a fairly large piece of carbonized wood was lifted
from Trench 14. This carbon was located near the site of the
carbonized wood with the stud found last season and not far from
the copper alloy stud found this season. Although no details
were immediately visible on the carbon from this season, there
was some thought that another stud or a finished edge might be
present. After pedestaling the area of dirt around the carbonized
wood, it was supported with layers of cotton gauze and Acryloid
B-72. Once fully supported, the carbon was lifted and will be
more fully excavated at the lab in Casa di Giotto.

Conservator Ellen Salzman
(always identified in the field by the hot pink hat) was called
in for
the meticulous and delicate work of lifting a piece of carbonized
wood from Trench 14.
Along with field work and treatments, this
week we conducted a ceramics workshop for the undergraduate students.
Due to the extreme fragility of the ceramics excavated on this
site, the students have not been able to assist in the physical
process of conservation. The purpose of the workshop was to provide
them with the opportunity to learn how to find and adhere joins
in an archival manner. In lieu of ancient ceramics, smashed modern
flower pots provided excellent surrogates. Much care and enthusiasm
in distressing the joins was supplied by many members of both
the conservation and field staff, ensuring a sufficient level
of difficulty for the students and more closely simulating actually
excavated pottery. All of the students approached the challenge
with a serious attitude of patience and problem solving. Although
not all of the vessels were completed, the educational exercise
will prove to be useful if the students are to continue in the
field.

Report 5: July 30
As the excavation comes to a close we are
faced with a large amount of material that has arrived in the
lab in the last week and a half or so. Since the influx of material
is directly related to which strata contain more artifacts, this
is not something which can be forestalled, although it has been
anticipated. At present we are finishing as many of the key objects
as possible and making sure that all of the rest are well stored
and archived so that treatment next year should be straightforward.
Mina and Ellen leave on Thursday, however, Andrew does not depart
until the next day. He has graciously offered to do the inventory
and pack up the lab after our departure, which leaves more time
for treatment up until the last minute, so we are fairly optimistic.
Well, we must rush back to the lab to do
as much as possible, so this is the conservators signing off
for the season--it has been a great one.
