Shellac Burn Effects for Encaustic Painting

This post was originally published in June 2011, it has been rewritten and update January 2025.

Shellac burn is a magical encaustic painting technique. With just a bit of shellac, a torch, and some practice, you can create flowing petals, soft foamy waves, or intricate organic textures that dance across your wax surface.

Understanding Shellac Burn Effects for Encaustic Painting

Shellac is a natural resin that, when applied over encaustic wax, creates feathery web-like textures when exposed to heat. The effects of a shellac burn can vary depending on factors such as application thickness, drying time, and heat intensity. Pearl Ex pigment powder can also be added to the shellac creating additional colour and shimmer in the burn effects.

Dry vs. Wet Shellac Burns

Dry Shellac Burn: Precision and Control

If you’re after refined, lacy textures with controlled detail, a dry shellac burn is what you want to try. Let the shellac dry completely before gently kissing it with a torch flame (set on low). Dry shellac will have a slower and more refined reaction, breaking the dried shellac into gorgeous, organic patterns as it bubbles and fractures.

Wet Shellac Burn: Unpredictable and Risky

A wet shellac burn is totally unpredictable. If you torch it before it’s dry, the flames take over, burning wildly across the surface. The artist has no control over the results or how the flames spread. While some artists showcase this method online, it is not recommended due to its dangerous and uncontrollable nature.

Safety Precautions for Shellac Burns

If you’re incorporating shellac burns into your encaustic work, follow these essential safety tips:

• Ensure proper ventilation: Shellac and encaustic fumes can be harmful, so work in a well-ventilated area or outside.
• Let the shellac dry before burning it.
• Use a torch with the flame set low for greater precision.
• Have fire safety equipment nearby: Always keep a fire extinguisher or fire blanket within reach when working with flammable materials.
• Practice on test panels: Experiment with shellac burn techniques on small sample panels before applying them to final pieces.
• Never leave an active burn unattended: Flames can spread quickly, so remain focused and prepared to extinguish any unintended fires immediately.

Give It a Try!

Shellac burn can transform your encaustic paintings, whether you’re aiming for dreamy florals, frothy ocean waves, or abstract textures full of movement. If you’re new to it, learning from an expert is a great way to build confidence. Check out a workshop with Alicia Tormey to begin the process with proper guidance. She even has online courses.
