Editorial note — INDEX

This part is stated to be a distinct piece cemented on to the bottom of the vessel. So at least says Mr. Apsley Pellatt in his Curiosities of Glass-making, writing, I think, before the vase was broken.

In the same book will be found a careful account of the process of ‘casing’ as now practised. It was probably by some such plan, in the case of the Portland vase, that the paraison of blue glass was blown into the previously prepared vessel of opaque white.
