Why Did My Candle Sink?

There's nothing more frustrating than spending time and materials on a beautiful candle, only to discover it has developed a sunken center or crater-like sinkhole. If you've ever asked "why did my candle sink?" you're not alone—this is one of the most common issues in candle making. The good news is that sinkholes are completely preventable with the right techniques and equipment.

The Main Culprits Behind Candle Sinkholes

Candle sinking typically occurs when the wax cools and contracts unevenly, pulling away from the center. Here are the primary causes:

1. Incorrect Pouring Temperature

Too Hot: Wax contracts dramatically as it cools from a high temperature

Too Cool: Wax may not properly adhere to the container walls

Solution: Find the sweet spot for your specific wax type

2. Rapid or Uneven Cooling

Drafty rooms, cold surfaces, or air conditioning can cause uneven cooling

The outer wax cools faster than the center, creating tension

3. Wax Type and Formulation

Some waxes are more prone to shrinkage than others

Pure soy wax is particularly susceptible to sinkholes

4. Container Temperature

Pouring into cold containers creates instant temperature shock

Master Your Pouring Temperatures
Each wax type has an ideal pouring temperature range:

Soy Wax: 105-135°F (41-57°C)

Paraffin Wax: 150-175°F (66-79°C)

Beeswax: 135-145°F (57-63°C)

IGI 6006 Blend: 155-165°F (68-74°C)

Using a ToAuto Wax Melter with digital temperature control ensures you hit and maintain these exact temperatures. The <a href="https://example.com/toauto-6l-wax-melter" target="_blank" rel="nofollow">ToAuto 6L Wax Melter</a> is perfect for intermediate users who need precise control over soy and IGI 6006 waxes.

Control Your Cooling Environment

Cool candles in a draft-free area

Place on a warm surface or use a heating pad

Cover with a cardboard box to slow cooling

Pre-Warm Your Containers

Heat empty containers to 100-120°F (38-49°C) before pouring

This prevents temperature shock and improves adhesion
