What Are Candle Jump Lines & How to Prevent Them
Jump Lines, also known as “chatter” and “stuttering” are the unintended horizontal lines or rings around the sides of either a container or pillar candle (see photo).
The lines give the wax a rough or slightly ridged appearance and prevent your candle from having that creamy smooth desired appearance. While jump lines are typically seen in container candles poured in clear glass, you often see them on pillar candles as well.
what causes candle jump lines?There are two main reasons candle jump lines occur:
- Pouring the wax at too low of a temperature
- The container (vessel or mold) is too cold
When jump lines occur, it is because the wax is congealing immediately and it is setting as more wax is poured on top of it, thus forming the “rings” or lines.
how to prevent candle jump lines
To prevent jump lines, make sure you are pouring your wax at the recommended temperature (pour temperatures can vary depending on the wax). You’ll also want to be careful not to heat your wax to a temperature that is too high; this can cause some of your fragrance to burn off, on top of causing other issues.
If you are in a cold work space you may need to heat your glass or molds before pouring into them. This can be done easily with a heat gun.
