Very heavy glass, little wear and a two part mould, the mark is not clear, a moulded 'L' have googled Libbey but can't find anything that looks like this ??? ;D
-
Inexpensive utilitarian ware made by at least several different companies. some with a molded line above the thumbprints. Very common c.1960s and 1970s., probably later. Some with a light color staining , blue or purple-red.

Thanks for the reply, for inexpensive glass, it is very heavy and seems well made ;D
-
And with a very thick bowl. It looks to have a properly heat finished rim that doesn't look machine made to me. ???
The foot and stem seem flimsier and machine-ier.
As to the L, I have a '70s Ravenhead Lager glass with exactly the same raised mark on it. It's an accident, a strand of glass that just got itself there and landed in a very neat capital L shape. It looks exactly like an elegant script.

Very thick ! the base of the bowl is at least an inch thick ;D

Libby version probably the first and best version. They were well acquainted with a form of machine fire-polishing since the 1920s with their patented "safedge". Some snippets of Carl U. Fauster's book "LIBBEY GLASS"
Len Beach Press, Toledo,Ohio. 1979 chapter V "Mid-Twentieth Century Expansion Years" 1943-1968 may be of interest. As follows: " In manufacturing, efficiencies were greatly improved and new processes were developed. As a result sales rose from 7 to 40 million dollars in the quarter century ending in 1968. [A very low inflationary time]. Manufacturing developments included more and faster machines, higher production speeds with increased efficiencies". "Good design and mass production made possible well-styled,quality glassware for the home at prices within reach of nearly every family".
