  1. Mosaic conservation-restoration on honeycomb support is well mastered and commonly used practice not only for restoration of mosaics in museums, but often for mosaics on archaeological sites.
  2. Reversibility or retreatability of  is always well considered in the conservation planning.
  3. Mosaic lifting is not always completely justified – it is a long-lasting  practice in the region, dating from the beginning of the 20th century; decision to detach nowadays is made for various reasons, often without consulting conservators-restorers and without making in depth inquiry on how to avoid it.
  4. Often, there is no planning prior to lifting on how and where to expose detached mosaics.
  5. Mosaics in museums are rarely exposed on the floor, even more rarely with reconstructed archaeological context, usually due to the lack of space; for the same reason many restored mosaics are not presented at all.
  6. There is certain insecurity regarding possibilities to preserve deteriorated bedding layers in mosaics and to restore mosaics in situ; worries include sudden decay of material due to changes in stable conditions in which the mosaic was found before excavation, influence of climate, selection of conservation materials and sustainability of implemented interventions, site management after the intervention (the tendency of the authorities to one-time financing of extensive conservation projects without long-term planning of maintenance), unsustainable conservation in situ due to irregular maintenance and preventive conservation activities caused by the absence of regular annual financing.
  7. Conservators-restorers often feel unable to influence decision makers regarding conservation policies and would appreciate support of professional organizations or other professional bodies.


This year's conference set route for the themes that need to be explored further. The next SEE Mosaics conference is planned for 2019 in Serbia with the theme “Conservation of mosaic bedding layers – when is impossible to preserve”.
