Who know where that glass came from It is flat like maybe it came from a stain glass window.The old lady used to be friends with a woman here who's father started a stained glass business. It was passed on to her and her husband. She decided she wanted to start a fitness business and was able to do so with money some guy flew in and paid her for an old Tiffany lamp her father had taken as payment many years ago. You are definitely right about them Tamrock. It is crazy, isn't it?
Someone probably tossed an old early 20th century Tiffany lampshade in the river in the 1950s when the style was no longer in fashion. Oh well if only they knew what the future had in store for old Tiffany lamps. I pickup old pieces of glass out in the old coalmine site behind where I live. Yours are all old slag glass.
