Hello Pat, I think this could possibly be the inner part of what is called a 'Brides Basket'.
These sat in a metal frame (silver?), and were usually frilly edged and either enamelled glass or the pattern was added to the glass during the making.
Have a look through the pictures of Frilled glass on Google, there seem to be several on there, and many have their makers names.
Please come back and let us know if this sounds correct and if you find a match for your bowl and the maker.
In the meantime I will keep looking as well.
