By November 1948, the restoration appeared aged and it was decided to restore the vase again. It was dismantled by conservator J. W. R. Axtell in mid-November 1948. The pieces were examined by D. B. Harden and W. A. Thorpe, who confirmed that the circular glass base removed in 1845 was not original. Axtell then carried out a reconstruction, completed by 2 February 1949, in which he was only successful in replacing three of the 37 loose fragments.[10] He reportedly used "new adhesives" for this restoration, which some thought might be epoxy resins or shellac, but were later discovered to simply be the same type of animal glue that Doubleday used in 1845. He also filled some areas with wax. No documentation of his work was produced.[citation needed]
