Origin: Abasiya 1 sector B
Date: January, 2016
Name of the object: Ab1B.15.164.45 (46/47/48)
Material: Pottery
Dimensions: Height 105 mm. Diameter 205 mm.
Description
Bowl of hemispherical body and flat edge with smooth surface exterior. No decoration.
Characteristics
Four fragments that allow to identify the complete profile of the pottery; therefore its original form can be reconstructed. Light brown porous ceramic paste with visible mineral and vegetable deflating particles. In one of the fragments can be seen some indeterminate white concretions.

Conservation condition
Regular. The four fragments constitute 40% of the whole vessel.
Objectives
Consolidation of the object and recuperation of its morphologic characteristics.
Minimum restoration needed to accomplish its stability and to be able to understand its original function, as well as for its future exhibition in the Karima Museum along with other ceramics recovered from the same site.
Treatment
Superficial cleaning with a solution mix of demineralized water and alcohol 96º (1-1). Mechanical dry-cleaning with brush and scalpel to extract soluble soil concretions.
Consolidation
Pieces joint together with nitrocellulose adhesive (Imedio banda azul®).
Restoration
Reintegration of part of the base with plaster dyed with natural sienna earth pigment (Conscolor). Consolidation of the plaster with a base of acrylic resin 2% Paraloid B-72® in acetone applied with a brush. Chromatic reintegration adjusting the color of the restored part with a drizzle dyed with natural pigments with acrylic resin 3% Paraloid B-72® solution in acetone.
Analytic study
We observed the white concretion or spot attached to the wall of the vessel under the microscope at 10x and 20x. It corresponds to a mineral conglomerate of fine grain. It has been performed a drop analysis (HCl 1%) that identifies a calcite matrix with siliceous aggregates, similar to the composition of the plaster used in the walls.
Recommendations for continued care and maintenance
Handle it as a block (with both hands)
Stable temperature between 24ºC and 30ºC
Do not expose directly to sunlight
Controlled dust-free atmosphere.
