Glass Chatroom Board

George, Bill and Cherryhill, Thanks for your awesome answers. I'm into British glass from the Victorian era and some companies used more uranium than others. It is hard to tell them a part sometimes in style, because the many English manufactures copied from one another. I wanted to know if there was a difference as a helpful guide in my searching of figuring out who made what. lol Nice to keep in mind, weight could be a factor if the glass has more uranium to point in the direction of a maker. Thomas Webb used more uranium than Richardsons to further explain.
Thank you again for your help.
