GregsonVaux Posted April 3, 2011 Share Posted April 3, 2011 I am interested in making glass geocoins and was hoping that some of you might be able to give a suggestion or two. The design will be inscribed using sand blasting, but I am not sure what to use as a blank. In other words, where do I find a glass disk that is about 2" in diameter with very flat faces. It would be best if the faces and the edge are polished. I found a manufacturer in China that will make them for me at a decent price, but they want me to buy a large quantity and shipping is a bit steep. Does anyone know anything that I can use off the shelf? Quote Link to comment
+keewee Posted April 3, 2011 Share Posted April 3, 2011 forthferalz would be a great place to start. Not sure if she spends much time on here these days or not, so you might want to contact her via her profile. Also several vendors have produced glass coins, but I can't remember who.

Does anyone know anything that I can use off the shelf? Could always use the bottoms of cola/beer/wine/champagne bottles. It might be a little more difficult... and you would have to try real hard to get enough samples That would be pretty freakin' neat, though! I love sea glass that gets obliterated by the ocean currents and the sand and salt. Keep us updated. Quote Link to comment

Maybe they have an idea for you. Thanks, I have seen those coins. My understanding is that the blanks were custom made, which would probably lead to a much more expensive coin. I am looking for something that is already being mass produced. For instance, it is easy to buy glass gems that look a bit like marbles, but are flat. I thought that I could use something like that, but I couldn't find anything the right size and flat enough. There are also Crystal Compass geocoins. Whatever they are using for blanks does not have polished edges, so they do it themselves. I am currently set up for engraving glass, though I don't have the ability to polish glass, or at least not yet. If I can't identify anything, I will have to go with the Chinese manufacturer. I would rather not do that, because even though their price per unit is quite good, the overall cost is high. They also want me to wire them money, which makes me very nervous. Quote Link to comment
+Eartha Posted April 3, 2011 Share Posted April 3, 2011 Google is your friend. I googled glass disc blanks, crystal blanks, and quartz blanks, and plenty of places came up. Maybe you have a local glass blower near you, who can make special orders. What's cheaper, paying for a few you will use, or buying way too many you may never use up? Quote Link to comment

A local person may be the way to go. I live in Pittsburgh, which is trying to build up its glass community and I would rather deal with local people. I think that I will start contacting people and see if I can come up with something. Thanks for the incentive. Quote Link to comment

The size will be either 2" or 2 1/4" dia. We used to throw the "plugs" out all the time. It's the hole we wanted. Typically the thickness would be 3/16" or 1/4" depending on the material used. Good luck! Quote Link to comment
