The objects on this page most frequently appear as table glass, including decanters, cream jugs, and salt cellars dating from the eighteenth and early nineteenth centuries. Alongside pure glass pieces, the selection includes silver baskets, salts, and dish rings fitted with cobalt glass liners.
Makers and craftsmen applied this distinctive blue glass across various tableware forms, sometimes combining it with silver wirework, enamel, or hand-painted decoration. The resulting items range from small bonnet glasses to multi-ring rum decanters.
How they were made
Glassmakers utilised lead glass and cobalt glass formulations to achieve the characteristic deep blue coloration seen in these pieces. Techniques such as wrythen moulding created spiral ribbed surface patterns on items like egg cups and cream jugs.
Metalworkers combined sterling silver, gold, and silver wirework with the glass elements, producing fitted containers like salt cellars and sugar baskets. Enamel work and hand-painted details were occasionally added to enhance the surface appearance.

What varies in quality
The refinement of the glass body and the depth of the cobalt colour distinguish finer examples from standard production. Uniformity in the blue tone and clarity in lead glass components indicate superior craftsmanship.
The integration between glass inserts and their silver or metal mounts reflects the skill of the makers. Pierced silverwork, swing handles, and hand-painted motifs demand precise execution, separating simpler items from more elaborate tableware.
