u want to sell any, that 2 tone lime green and the clear with the yellow orange look sweet, or if you have any chunks of that stuff.

Oh wow! Those are all beauties! They tumble up just like obsidian too and make some amazing cabs! Fran

If you rough tumble them, you end up with what looks exactly like sea glass, with the neat frosted textures:).

Thanks for the comments.I have collected this glass over a couple of years.I got 1 piece of each different color I run across. Most pieces are 1-2 lbs each.Not sure yet what to do with them,my options are open.My grandkids love the glass,and " Papa, can I have this"?wins out. Been using them on window ledges snuffy

I have tumbled glass to frost and round it.I wonder if it is difficult to take all the way to polish?Just like obsidian i guess.That is a wild collection Snuffy.Owens Corning fiberglass plant is close to me.They break out glass ever so often.It collects in a big pan in their ovens.I have heard it is 2 feet deep and big like a tennis court.All clear to green and lite blue.

I have tumbled glass. Easy and quick. Have made faux sea glass and polished it shiny as well
Snuffy your glass is way to nice to make it frosted in my opinion. I would cut it and shine it up. My mouth is watering over your slabs

The glass does polish in a vibe, I use broken/bad glass as filler in my tumbler, and if I take it all the way to polish, it will shine up again... but not as crystal clear as heat melted glass.
Still, it gets pretty close and way closer than 'frosted'. It is man-made obsidian, so will tumble and polish just like obsidian:).

So i could heat polish my tumbled glass that is only frosted?What is cheaper,acetylene or grit/electricity?

So i could heat polish my tumbled glass that is only frosted?What is cheaper,acetylene or grit/electricity? Well, the torch may be a bad idea. Reason is that glass has an amorphous structure, it's infinitely pliable... but only stronger when the crystals interlock. Any manipulation and the crystals can be pulled out of that interlocking. That's why we anneal glass in a kiln afterwards, like a rubber band, slowly reducing heat gives the glass a chance to fall into the interlocking pattern it likes. That said, just melting the surface may knock out the interlocking. What does that mean? Your glass structure is weaker and can break later, sometimes without even being touched. Annealed glass is insanely strong and hard to break, the thicker it is, the stronger it is. I understand that making tempered glass is to intentionally break the interlocking into much smaller bits so it fragments on impact, instead of breaking at the weakest points only, but you can see how the weakness works. Hit one stress point correctly and the entire sheet shatters, no matter how big the sheet is or how small the stress point. With a properly annealed glass sheet, only the corner you hit could break off, in a super sharp jagged piece, and probably not break at all from the type of stress point impact that would break tempered glass… properly annealed glass has no stress points. This may not matter at all for say fish tank decoration or to sit in a jar, but it's why we anneal glass for jewelry use. Broken glass has dangerous edges, so it needs to be made as strong as possible first. Snuffy's pix of tumbled glass are a great example of how close you can get to perfectly polished. Keep in mind that this is soft glass and not borosilicate anyway, so at best, it's closest to window glass and not telescope lens clarity. Those tumbles are very clear, and very good:). I wouldn't use a torch without a kiln if you want to make jewelry from it, there's no telling how weak the glass structure may already be, and making the surface molten would stress it further. On the other hand, with a kiln, you can torch glass to your heart's content, manipulating it with tools, sticking it into molds, etc. You may enjoy working glass James. The fastest way to see if you'd like it is to take a local glass class, there's several glass studios in and around Atlanta I have heard of that teach basics. Then, we can talk glass too:).

Just thought of something you guys who might be interested in glass may want to check out. A few years ago, I wrote a beginning borosilicate article for The Flow Magazine (the industry glass artist's magazine). After publishing it, they put it online for one of their tutorial downloads because it's so basic. I wrote it for people already familiar with working soft glass, as an intro to boro glass sculpture... but it's still enough to give you an idea of the skills you need to master to work borosilicate (and sculpture- which isn't really a whole lot different from working soft glass sculpture, except for timing the glass). If you are curious about actual flameworking, check it out (and the magazine too, it's THE glass magazine, with lots of tutorials every issue): www.theflowmagazine.com/index.php?option=com_k2&view=item&id=355:theflowwinter2009helen-starkweatherbororodtipsfornewbiespdf&Itemid=66&qh=YToxOntpOjA7czoxMjoiYm9yb3NpbGljYXRlIjt9Meh, won't give you a direct link because it's a HTTPS secured address. Just cut and paste the above link.
