When your candle reaches wick's end, please recycle or, better yet, repurpose the glass container. I've shared a few very simple ideas above, but I'd love to learn about new & imaginative ways to refresh the glass from y'all. Note that reuse as a candle jar is not included as doing so is not safe given that glass weakens as a result of use.
Get that creative motor running & don't forget to share your great ideas. Ready, set, create!
