Newton Posted July 10, 2023 Report Share Posted July 10, 2023 I picked up this clear marble in a thrift store. At first I thought it had a vey pale colored ribbon on the surface. I cleaned it at home and what I thought was pale color is actually etching. No color and the ridges can be felt when running a fingernail across the surface. I haven’t seen anything like it before but thought you folks may have and it could be just some common thing. Ty for any comments. 1 Link to comment Share on other sites More sharing options...

Jeff54 Posted July 12, 2023 Report Share Posted July 12, 2023 Sorry to say but none of the above. This was made to produce fiberglass. Many are found around railroad tracks and transfer stations which is also how some nonsensical stories linger on the net about these. . Made in the USA since the late 1930's and several other countries like China etc. where fiberglass is produced. Link: Fiberglass manufacture, Owens-Corning, Toledo, Ohio. Millions of carefully inspected glass marbles ready for remelting and forming into glass filaments. A single marble can be drawn into a continuous filament so fine that it could reach from New York to Philadelphia. More than one hundred filaments must be drawn together to make the finest workable strand - PICRYL - Public Domain Media Search Engine Public Domain Search 1 1 2 Link to comment Share on other sites More sharing options...

They had/have their own rollers to make the marbles, shown here: Fiberglass manufacture, Owens-Corning, Toledo, Ohio. This is the machine that forms clear glass marbles in a plant of the Owens-Corning Fiberglass Corporation. Marbles are fed as raw material into electric furnaces from which they are drawn into fibers one-twentieth the size of human hair - PICRYL - Public Domain Media Search Engine Public Domain Search 1 2 Link to comment Share on other sites More sharing options...

Ric Posted July 18, 2023 Report Share Posted July 18, 2023 I think it's probably feedstock for fiberglass production too. 1 Link to comment Share on other sites More sharing options...
