Troubleshooting Jump Lines

What are jump lines?

Jump lines (also known as chatter or stutters) are thin rings or horizontal lines that form along the outer edge of container candles and pillar candles.

Why do jump lines happen?

Jump lines only occur with paraffin wax as it has a higher melting point than plant waxes. When hot paraffin wax (usually at 65°C to 70°C) is poured into room temperature glasses, it solidifies very quickly along the edge of the jar, even as more wax is still being poured on top of it. This then forms jump lines.

How do I avoid jump lines?

Choose opaque candles

While they are not aesthetically pleasing, jump lines do not impede candle performance. Therefore, avoiding clear candle jars and choosing opaque ones will hide any jump lines.

Pre-heat candle jars

We recommend heating your candle glass jar to 40°C to 45°C before pouring to prevent jump lines from forming.

Increase the pouring temperature

When using paraffin wax, heating the fragranced wax by 5°C to 10°C more than its melting point will help to avoid jump lines.
