I have some beach glass that I'd like to attach to an old chandelier. Anyone got any ideas on how to do that?

Drilling into glass causes a lot of heat due to the friction of the drill bit. So, water would be useful in preventing the glass from getting too hot and breaking. I found that out the hard way.

So, instead, I got creative. I went to a craft store and found some interesting items in the jewelry making supply aisle. I bought small metal jewelry findings (that is what they are called-findings) to glue on the edge of the sea glass/shells, to which string can be threaded through the loop on the top. I did not care for the fishing line "look" I used to hang the sea glass/shells on the chandelier, so I got some seed beads, in sea glass colors and strung the fishing line with tiny beads and it came out fantastic!!

I bought an old ugly brass chandelier at a flea market for $5.00, removed the wiring, spray painted it with Rustolium white paint and decorated it with sea glass/shells as described above and put candles in it. With a long wire, I hung the chandelier from a tree. The chandelier now graces the area over an outdoor table in our beach property. Love it!!

P.S. I used outdoor glue that dried clear to attache the jewelry finding to the edge of the sea glass and shells. You will have to bend the metal "feet" of the jewelry finding to conform to the glass shape before gluing.

Go to a Shop that specializes in Glass and They will set You up with the correct drill bits and give You the info You are asking for.

I like 'Common Sense's" response very much! If you go that route, you can purchase metal glue in the beading area that really grips the metal findings.

You could also try drilling with a Dremmel tool. They have many tiny bits that would probably go through the glass.... test it out on your least favorite piece first.

Sounds like a fun project! Have fun! :)
