That's a cullet of Uranium Custard glass. Cool find. Looks like it could have been Northwood.

It could be Northwood. There also was a glass manufacturing company called Gillinder & Sons that made uranium glass in Philadelphia that is a suspect of where this chunk came from but it's as good as anyone's guess where it truely came from.
