ABSTRACT Many countries in the Mediterranean region face the enormous challenge of conserving detached mosaics abandoned in storage for decades without any re-backing support and with only their facings to hold the tesserae in place. As part of the MOSAIKON initiative's technician training courses, sustainable techniques have been developed to address this problem, providing national authorities with the skills and knowledge to begin to provide proper long-term storage for the significant backlog of detached mosaics under their care. Mosaics in storage at the sites of Volubilis in Morocco and Sidon in Lebanon have provided the opportunity to develop new documentation and treatment methodologies. Low–cost techniques were sought using purpose-built, locally-constructed shelving structures and lime-based mortar re-backing supports which allow the removal of deteriorated facings and the identification and stabilization of the mosaics for long-term storage or eventual display in a museum or re-laying on site when more substantial funding is available. In both cases, the absence of sufficient storage facilities nearby the sites led to the lifted mosaics’ transportation to other locations within the country, highlighting the lack of planning when the excavations took place. Lack of surviving documentation about the mosaics has in both cases necessitated a treatment and storage approach which favors reversibility, accessibility and portability.

应对保存和维护存储中的马赛克的挑战

摘要 地中海地区的许多国家都面临着保存被遗弃数十年的分离马赛克的巨大挑战，没有任何重新支持，只有它们的饰面才能将镶嵌物固定到位。作为 MOSAIKON 计划的技术人员培训课程的一部分，已经开发出可持续技术来解决这个问题，为国家当局提供技能和知识，开始为其照料的大量分离马赛克提供适当的长期储存。在摩洛哥的 Volubilis 和黎巴嫩的 Sidon 站点存储的马赛克为开发新的文档和处理方法提供了机会。寻求使用专门构建的低成本技术，本地建造的搁架结构和石灰基砂浆重新支撑，可以去除损坏的饰面，识别和稳定马赛克，以便长期储存或最终在博物馆中展示，或在获得更多资金时重新铺设在现场可用。在这两种情况下，遗址附近缺乏足够的储存设施，导致被抬升的马赛克被运往国内其他地方，这突显了挖掘时缺乏规划。在这两种情况下，由于缺乏关于马赛克的幸存文件，因此需要一种有利于可逆性、可访问性和便携性的处理和存储方法。
