Most candle makers find using molds the most straight forward and versatile way to make candles. Using a mold, a candle can be made in virtually any shape imaginable. 

There are two concepts that need to be considered when evaluating a candle making mold and shape. These characteristics are draft and undercut.

Let’s talk about draft first. Draft is the degree of taper in a mold. Without the taper, it would be difficult or impossible to remove the candle from a solid mold.

It’s possible to make candles in molds with parallel sides because wax tends to shrink slightly as it cools, thereby separating from the mold enough to allow it to slide out.

Undercutting is another term you should be familiar with. An undercut is a protrusion or an irregularity in the side of a candle that would keep it from sliding out. This becomes a factor when using molds to make candles with irregular walls or shapes.

Undercutting in a form prevents using solid, one-piece molds to make the candle. There are two ways of handling the situation. One solution is to use a mold that separates into two or more parts. Another approach is to use a mold made out of rubber or other flexible material that can be stretched to allow removal of the finished candle.

Two-part molds work well for making candles that are symmetrical.  You could also use a flexible mold, but it isn't required for this type of shape and rigid multi-part molds are more durable. When using a two-part mold, the candle maker clamps the two halves together, positions the wick, pours the candle, and finally separates the two halves of the mold after the wax has hardened.

As I mentioned, you can also deal with undercutting by using flexible molds, which can be stretched to allow the candle to be removed once it has hardened. These molds are often made of silicone or rubber or other plastic materials.
