The Portland Vase shown to the left is the most famous cameo-glass vessel from antiquity, perhaps from Rome, Italy, about AD 5-25
It was badly damaged afer being smashed by a vandal in 1845.
Only recently has the British Museum been able to successfully restore the Portland Vase to its former glory!
Several different adhesives used for the previous restorations had all failed. To find an adhesive that would last for much longer, conservation scientists at the Museum tested many adhesives for long term stability.
Finally, an epoxy resin that had shown excellent ageing properties was chosen… and that was HXTAL NYL-1 Epoxy Adhesive.
The newly conserved Portland Vase was returned to display and, except for light cleaning, should not require major conservation work for many years to come.
