Glass ear plugs?
Is anyone still making these?
Are they always made with Boro or can they be made with soft glass?
Are they only made off mandrel or can they be made on the end of mandrel?
Any videos or tutorials out there?
I recently was asked if I could make these. I'm clueless about where to start.
Previous posts are kinda old, so I didn't know if anyone was still making these. It seems the market is flooded with mass produced over seas cheap plugs, so I didn't know....
Thanks
Kristin
