How long will a globe ice lantern last OUTSIDE?

The length of time a globe ice lantern will stay beautiful depends on how big you make it; how thick it is; where you display it; the outside temperature; and what type of candle you use.

Put a small or large, relatively thick (at least 3” thick walls) globe ice lantern outside in the shade during winter temperatures and occasionally burn a standard parafin candle in it, and it could last most of the winter.

Put the same globe in the sun, and it will shrink slowly for a month or so, but the sun will etch beautiful lines into the globe so at night with a candle burning inside, the light will dance!
