'Rosaline' was indeed a name used by Steuben - Newman say of this.............."a type of jade glass that is rose coloured. It was made by Steuben Glass Works".
The Grover's discuss this 'jade aspect of the Steuben production - Rosaline in particular - and they draw attention to the similarity with S.& W. material and that of Steuben - commenting that unless pieces are marked then it is quite easy to confuse the two.
And the reason for this similarity of the 'pink' glass from the two factories, is that Carder was the art director of S. & W. - and then presumably some time in the first decade of the C20 went to Steuben where he remained as art director until the mid 1930's ish, I think.
The Grovers show examples of Steuben 'Rosaline', although I don't think the colour of the pix is particularly good, and could be misleading. The book was produced in Japan back in 1967, when colour reproduction may not have been that faithful to the real thing.
Actually, I thought it was a girl's name.

P.S. obviously I can't spell 'florid'
