I was thinking about doing some of this..just for the fun of it. I understand that glass grinds quickly and you have to watch it. Especially in the early stages. A question is where would you get some thick glass to tumble ?? I mean it would be no problem to find beer bottles and window glass.
Thanks Dwight P

I have a network of people at work saving me empty wine bottles of various colors. It's a free source of glass and even though the sides might be too thin on some of the bottles, I can just use the bottoms and recycle the rest. I also keep an eye out for small glass juice containers. They are usually made of thicker glass than bottles.

Hi guys, I've been quiet for a while but I'll try to make up for it. The glass I have came from a glass factory over in Pa. If you can find one near by you, it would probably be worth the trip. They usually have loads of old slag glass that gets trashed, so they often sell it off for next to nothing. There is one large glass factory in W.Va. that has a recycling company down the road that handles all their waste glass and they sell it to the public for them for around $1.00/lb. Still not a bad price. The pieces are what gets knocked out of the melting pots after a pour and are mostly good sized pieces near boulder sized (at least in the places I've been). You can find some interesting colors and mixed glass of all types. I just finished another batch of slag glass finally ( poor mans' gemstones) and they turned out well. Here is a pic of some of it with a close up of a piece of colbolt blue on the right. Love that stuff! I also did a little more of that crazy photocromic glass and took this pic to try and show the color change better. I really like this stuff, it captivates me for some reason. The top part of the pic is taken in incandescent lighting and the bottom in flourescent lighting. The photocromic glass is the second group from the left. Happy tumbling all, later, Don

That glass is beautiful! Well tumbled. I facet and get my shine from the phenolic plate. I have never gotten a polish from tumbling that looks like that. Georgeous.

Thanks doc for the kind words! But I should mention this. It is hard to figure. In reality, only about 2/3rds of that load of glass took a good shine. There were 3 colors of glass in it (pink, amber, and clear) that looked great until they dryed. They hazed over with a milky fog on their surfaces. They appear to be super polished and smooth, but hazey. I don't know exactly why, but it seems that some of the glass is just of a different enough make-up to do that? Maybe a tiny bit softer? It has got me baffled. There is one piece that has both types in the same rock, it is really nice on one side, but the end with the amber color is hazy. I tryed a tiny bit of oil on one of them and bingo, the haze disappears and they look just like the others. I had run this batch for 14 days in final polish. I think I will just oil the other hazy pieces rather than fight them any longer. Has anyone else experienced this? Talk to you later, Don

FYI pic of the hazing problem, so you can see what I am talking about. How do you guys across the pond like my choice of oil? ;D Later all, Don

Cool, does it yellow with time? I use linseed oil for emeralds. I like the finish.
