Janine,
Yes; the first bird done in the shaded glass is called "Blue Burmese" by Fenton, who it appears has often abused a number of other names and terms used in antique glass collecting for what seems to be the sake of sales or just lack of originality.
The second bird is not Blue Burmese. Fenton calls it "Blue Satin", which could be taken as "Satin Glass", but this Fenton glass has been sand blasted and is rough enough to file one's fingernails with, so there isn't much about it that resembles or relates to Satin the fabric or what's known as "Satin Glass" in any way.
The third bird is Custard Glass and Fenton calls this "Custard Satin". This too could double as a finger nail file.
Fenton has and still does make some very nice things, which would likely do well by any name they gave them. Their use of these names and terms for items that are not related to the original glass of those names etc., tends to cause confusion for folks who don't care about Fenton glass and are more interested in the glass those names and terms were originally applied to. --- Mike
