Like Mandarin Yellow, rouge Flambé was also inspired by Chinese porcelains; both these glasses were made in shapes suggestive of oriental ceramics, and both were difficult to produce and particularly vulnerable to breakage caused by strains with the glass.

Rouge Flambé pieces range in color from a rich red which was the color Carder was seeking, to an orange or coral tone. The color was produced by the addition of selenium and cadmium sulfide to the glass batch. As a result of the production difficulties, Rouge Flambé was made for only about two years, probably in 1916 and 1917.
