I was hoping this was uranium glass, sadly not, but I think it's an unusual colour. It has a rough snapped pontil and wear on the bottom in the form of a ring of dots on the contact points of the ribs. I believe it was made in Stourbridge but by one of the lesser known makers such as Smart Brothers . P.311 in Hajdamach 1800-1914 shows some not dissimilar pieces with the same type of rigaree in cranberry glass. I can't find much about Smart Brothers online.
