Some companies and workshops that manufactured cameo glassware include Thomas Webb and Sons, which often used a “GEM CAMEO” maker's mark; Emile Gallé, which used its brand name on a paper label or as an etching directly onto the glass; and Verrerie Schneider, which utilized its name or the word “CHARDER” as a marking.
