The candles should be fine, the heat will go up and not all the wax will burn so the glass will be shielded. The trick in making the glasses is to twist the bottle so the heat goes round the glass. Quite interested in making the candles, might look into that some more.
In terms of safety, providing you sand it down well enough and check for fractures you should be fine. I can't see how a stray bit of glass would get in.
Lucero, yea it didn't break particularly clean. I used big, straw like string rather than the smooth white stuff I should have used. I think that the knot caused issues. I tapped that shard with the back of the scissors and it came away pretty neatly. I then sanded it down.
Looking at the glass, it's pretty rough still with one quite big 'peak'. However, it's perfectly smooth. Even pushing my finger down as hard as I can on it, and moving it back and forth, I don't cut myself. I'm sure with better string, and more practise it should be a perfectly clean break.
