Among the many objects that were newly restored and preserved for the 2012 exhibition were two Roman glass vessels - a turquoise jug (1-232-72) and a greenish flat bowl (1-223-75). Both objects were in poor condition: the surface was dirty, the bonds were poorly executed, and several of them had already dissolved.

​

• Surface cleaning with ethanol

• Cleaning the joints with acetone / dissolving old bonds

• new composition of the shards with dextrin strips

• Infiltration bonding with Araldite 2020 epoxy resin

​

In the case of the shell, no stability could be achieved with the adhesive. The flaws were therefore supplemented with slightly colored Araldite 2020. A special silicone sleeve with a plaster cap was made for this.
