The conservation laboratory of stone objects operates since 2012. It is equipped with modern technical means for the conservation of the Museum collection. The collection includes sculptures, architectural and ornamental items, utilitarian objects and tomb stones, dated from the prehistoric to the post byzantine period. The objects are mainly made of marble and to a lesser extent, limestone and other stones.
The laboratory deals with both preservation and conservation. The preservation work involves stabilizing corrosive agents, surface cleaning, consolidation, adhesion of fractured parts, reinforcement of joints and fillings wherever it is considered necessary. Mild materials and methods are used in combination with macroscopic and microscopic observation, qualitative and quantitative analyses of the objects.
