Northwood's reproduction of the Portland Vase was damaged on a trip to London, but not on the trip to claim his prize. There are multiple accounts of the accident, but it seems as though something (washing the reproduction in warm water, especially cold weather, the different types and thicknesses of the opal and dark blue glasses) caused a crack in the body of the vase. This happened while Northwood was preparing to go to London and compare his vase to the original one last time. Northwood was able to repair the vase to his (and Richardson's) satisfaction.
I used Robin Brook's The Portland Vase (2004) and John Northwood II's John Northwood: His Contribution to The Stourbridge Flint Glass Industry, 1850-1901 (1958) for the above information, but I have also attached our bibliography on Portland Vase reproductions for additional sources and further information.
