akroorka Posted July 7, 2022 Report Share Posted July 7, 2022 Here are a few very nice bullet mold marbles that just boggle my mind. Almost perfectly half and half with very nice clear glass, they are very round with no imperfections. They are just under 5/8”. How are these made?? I cannot wrap my mind around this! Thanks for any and all opinions. Marble—On!! 1 Link to comment Share on other sites More sharing options...
William Posted July 7, 2022 Report Share Posted July 7, 2022 I've always wondered about the colors...mold injection process I assume? I've never researched bullet mold marbles at all. It would be interesting too see how they are made. Also too see any differences from how they were made 100 years ago vs. today. I'll have to find time to check it out 😊 Link to comment Share on other sites More sharing options...
