I have a set that consists of a small pitcher (approx. 6 inches high) and a matching creamer. They are both very heavy clear smooth glass (that is a little wavy when you look through it), with an interior coloring of very deep emerald green at the base, flowing up about an inch in a "splash" sort of pattern.
I think they are blown glass, and I suspect they may have come from one of the Ohio glassworks. They have been in my family since at least 1950.
Any help in identifying the maker would be appreciated.
