ON-SITE SAMPLING TECHNIQUES USED FOR OPTIMAL SALVATION OF HERITAGE OBJECTS
On sampling archaeological ceramics, special problems may arise when within some archaeological complexes are discovered whole vessels especially, the case of prehistorical or prefeudal ceramics, which mostly, was burnt at low temperatures, technological aspect that influences negatively the conservation state of these categories of vessels.
These vessels, in most cases fragmented following soil’s pressure, may form real time capsules, the inside soil could hide a series of important vestiges or contain different quantities of pollen, seed etc.
For this category of objects, especially if the vessels are found in an advanced degradation state (strongly fragmented, paste burnt at low temperatures, degradations as consequence of action of the soil and vegetation etc), the most recommended sampling method is binding.
Subsequently to transportation within restoration laboratory, vessels will be processed within different stages that take into consideration the conservation state, type of fragmentation, presence of other artifacts inside.
In some cases, out of different reasons, fragments of a vessel (even funerary urn) may be scattered perimetrically on a relatively big surface, fact which does not allow application of the binding. In these cases it is recommended sampling in the lump or on support, more complicated operations necessitating specific materials and an elaborated work procedure which involves a great deal of work, aspects that cannot be always dealt with in the archaeological site.
Following objective evaluation of the conservation state there may be appealed to a series of measures by which artifacts to be kept away from action of factors of external environment until we are able to establish methodology and necessary equipment to apply the above mentioned methods, or in certain cases a compromise method may be applied.
This includes division of the complex into squares, and fragments are sampled and packed separately into groups that contain 2 to 10 fragments.
Both methods allow sampling and successful processing of ceramic pieces and allow optimal preservation from the point of view of conservation state for long periods of time before undergoing the proper process of restoration.
