Candle pouring hot wax

Pouring hot wax into molds is a central step in handmade candle making, combining technique and safety.

About this subject

The technique of pouring hot wax into molds is essential in handmade candle making. Wax, typically paraffin, soy, or beeswax, is heated to specific temperatures between 60°C and 80°C depending on the type. The correct melting point ensures the candle burns evenly and without excessive smoke. This process requires care to avoid burns and to prevent the wax from solidifying before fully filling the mold.

Historically, candles were made by dipping wicks in animal fat or beeswax, but the molding method gained popularity in the 19th century with industrialization. Today, artisans use molds made of silicone, metal, or glass to create various shapes, from simple cylinders to complex sculptures. The addition of dyes and fragrances occurs at the time of pouring, requiring homogeneous mixing for even distribution.

Interestingly, wax temperature directly affects the final texture. Wax that is too hot can cause excessive shrinkage or air bubbles, while wax that is too cold results in an uneven surface. Therefore, many artisans use kitchen thermometers for precise monitoring. Additionally, the environment should be free of drafts to avoid thermal shock that could crack the candle.

In Brazil, artisanal candle making is a tradition at June festivals and religious celebrations, such as prayer candles. The manual pouring technique gives authenticity and artisanal value to the final product, contrasting with large-scale industrial production.

Frequently Asked Questions

What is the ideal temperature for melting soy wax?

For soy wax, the ideal melting temperature is between 65°C and 75°C. Above that, it may burn the fragrance or cause discoloration.

How to avoid air bubbles when pouring wax into molds?

Pour the wax slowly in a thin stream. Gently tapping the mold on the counter or using a stick to release bubbles also helps prevent imperfections.

Why does wax shrink after cooling?

Shrinkage is natural because wax contracts as it solidifies. To compensate, many artisans do a second pour a few hours later to fill the cavity that forms.
