Is there a suggested length of time I should burn the candle for?

YES! Make sure you light this candle when you have at least about an hour to kill. You'll want to make sure not to blow it out until the wax "melt pool" reaches all of the sides of the glass. As delicious as these candles smell, try not to burn for more than 3-4 hours at a time. 

Is it true that I should trim the wick before use?

It's always a good idea to trim the wick to about 1/4" before lighting your candle. This will prevent the flame from burning too high and smoking. A 1/4" wick will give you a few hours of perfectly burning candle and a progressively more fragrant melt pool.

When is it time to retire the candle from use?

It's a good idea to retire your candle when about 1/2 inch remains in the bottom. It's not the safest idea to keep burning at this point due to the wick moving around and the glass getting really hot. But don't worry, there is more you can do with the beautiful jar. 

You'll want to scoop out the remainder of the wax with a spoon or butter knife and dump into the trash. Then rinse the remainder of the wax out with a little bit of hot soapy water. Try not to pour wax down he drain (can cause serious plumbing issues). 

At this point, you're creativity takes over. Fill your dilo. amber jar with good looking plants, paint brushes, small bathroom items (toothbrushes, cotton balls), fire flies, or whatever else you can fit in there. Make sure to post and share your ideas with us.
