I've checked out the link given
![Kiss :-*](http://www.glassmessages.com/Smileys/classic/kiss.gif)
, and there is in fact a "smoke olive dish" on page 41 of their catalogue, described as "Colourless and transparent smokey grey glass; blown, hot worked, applied. Transparent smokey grey dish with one applied colourless scroll handle. Design 9674". This has an engraved base.
I initially thought mine was smoke brown, but it is grey. The handle on mine is smoke grey unlike the Steuben catalogue one, which if I read it correctly, is clear, and the dimensions are different too.
Some fabulous glass in the catalogue.
