Candle Wax Sinks In Mold Problem
Troubleshooting Guide

This is technically not really a problem, but we've included it here as many beginners think it is when they first encounter it.

Wax Sinks As It Cools
Wax, like everything else is subject to the laws of physics - it expands when heated and shrinks when cooled. This is actually a good thing as it is what makes mold removal easy. The amount of shrinkage will vary with mold size and wax formula.

Prevention - There is no way to defy the laws of physics. But there is a workaround:

Metal Votive Pouring Procedure.
This procedure positions the pouring line at the edge of the candle where it is not visible.

1. Place the molds in a tray to catch spillage for reuse.
2. Make the first pour until overflowing.
3. Position the wick if not using auto wick pins.
4. Allow to cool until wax is firm, yet still warm. If not using auto wick pins, periodically grasp the wick and tug gently up and to the center.
5. Make second pour allowing wax to overflow molds.

Most Other Molds Procedure

1. Make first pour to 1/4 inch from top of mold.
2. Poke several relief holes near the wick. This will help bond the second pour.
3. Allow wax to cool until hard.
4. Make the second pour stopping 1/4 inch below the first pour line.
5. When cool, remove from the mold and level the base using a heated pan or electric griddle.

Container Candles

1. Make the first pour to desired level.
2. Position the wick once bottom gets "cloudy".
3. Allow to cool until wax is firm, yet still warm.
4. Make a second pour as close to the level of the first pour as possible.
