'Dresser had been invited to serve as a ceramics juror at Philadelphia, in 1876, but declined because of his preparations to visit Japan, however he did serve as a wallpaper juror at Paris in 1878. Clearly the international recognition of both his 'ceramic' and his 'wallpaper' expertise was well established. This was not his only achievement for he noted that:
'Eleven manufacturers engaged in eleven different branches of manufacture showed my designs at the last Paris Exhibition, and ten of these got gold medals and the other silver.' 25.
Amongst the English firms who had produced Dresser designs and who exhibited at Paris were:

Thomas Webb & Sons winners of the Grand Prix, which 'was not awarded for purity of metal only; it was for cutting, and engraving, and designing on crystal glass.'FIG.16 The Art Journal of 1878 noticed that 'Other glass is pure in colour, but the finest British flint glass has a brilliancy that appears nowhere else.' They also exhibited Bronze glass for the first time. FIG.17

It is a source that states Thomas Webb produced Christopher Dresser designs.
It does not state that he designed the Bronze glass.
