No pontil. Interesting. I never would have guessed since my only citrate of magnesia is a crown top. Thanks!That looks like a really old one to me! Is it pontilled? I think it's a citrate of magnesia based on that top, but a lot older than your typical citrate.
Thanks! Yes it is a pretty blue. I wish I had a tumbler. Just can't justify the expense right now. I wonder if it was always cloudy or part of the breakdown of the glass.that looks like it would polish up to a really neat cornflower blue, not just your typical aqua. 3x on citrate of magnesia. They seemed to be a product that came in very uniform packaging.
