Following up on our surfeit of wine bottles problem and consequent attempt at re-use, I've been tumbling glass all week.
After five days in the four-pound tumbler with some very coarse grit and some plastic pellets (to prevent the glass from shattering and chipping), I have some smooth and rounded pieces from what were once deadly shards.
But though they be smooth and rounded, they also be ugly.
I can no longer see the pretty amber and green colors (can you?) because the pieces are so heavily frosted (i.e., dulled) from the coarse grit.
So the troubleshooting begins:
1. I can try re-tumbling with some fine grit in the hope of polishing the glass. (A lost cause?)
2. I can try again from scratch with new shards of wine bottles, using a finer grit from the start.
Since I have no idea what use I am going for, it seems a little silly to get too particular--or too disappointed. Clearly, whatever it is I have just produced isn't going to work for jewelry or art (which was one of my original goals).
So, if I can't bring back the sheen on this batch, I was thinking of just dumping it in an empty flower bed as a kind of funky xeroscaping...?
Advice from glass-tumbling boffins would be most appreciated.
