There are a variety of earthenware sherds recovered from the Ille excavation. Unfortunately none
of these finds can be associated with confidence to any of the surfaces recognized at the site.
There has been so much large scale turbation (human and natural) at the upper layers where the sherds
were recovered that it is safer to assume that all these artefacts were in secondary deposition; mostly
as part of fills for burial pits dug through the centuries.
From the recovered decorated sherds, there were various designs. Based on discussions and comparisons
with previous archaeological studies, some of the designs can be trace back to time depths of 5000 to
4000 years ago, such as the red-slipped pottery sherds with impressed circular design; in some pieces,
these impressed circles are filled with a white substance most likely lime or white clay.
A variation of designs, mostly geometric forms, some painted red, were also recovered from the site.
These types of pottery were usually associated with what is conventionally called the "Metal period"
in Philippine archaeology (roughly 2500 to 1500 ya).
Undecorated large and thick pieces of sherds were also recovered. These fragments may have been
part of burial jars deposited at what was the surface of the site at that time. The quantity observed
on-site however does not indicate an intensive use of the place for burial jar interments.
There are relatively few tradeware ceramic sherds at the Dewil valley. However, just outside the valley,
at the Sinalakan cemetery site, which was thoroughly pot hunted, there is an abundance of tradeware ceramic
grave goods as reported and seen during the 1998 survey.
There seems to be a limited presence of tradeware pottery in the valley. At the Ille platform, the only
tradeware pottery sherds recovered were brown stoneware sherds from large jars, a few celadon sherds, whiteware,
and brownware sherds that may come from 12-13th century made pottery. These large brown glazed sherds that
came from the surface and sub-surface fills were determined to be "dusan" jars from the 10th century, as opposed
to the initial idea that they were "dragon" jars from the 17th century or younger (see Valdes et al. 1992).
Having said this, at the top of the Ille tower, there are blue and white sherds scattered at the surface in
numbers that make them easy to pick out.
