Which pigments should I use for volcano effects?

Recommended Pigment Types

For epoxy volcano effects, always use pigments designed for compatibility with resin. Suitable options include liquid epoxy dyes, mica powders, and paste pigments—these blend smoothly without clumping or interfering with the curing process. Avoid water-based or acrylic pigments, as they can impact clarity and setting.

Colour Choices for Lifelike Lava

To create convincing lava, focus on translucent reds, oranges and yellows. Layering these shades produces the glow and depth that mimics molten rock. Use black and brown pigments for the surrounding volcano structure and base to contrast with the bright lava details. Try blending touches of metallic mica for reflective highlights, which can enhance a glowing, active look.

• Translucent red and orange for lava flows
• Yellow for molten highlights
• Black and brown for realistic rocks

Practical Tips and Buying Advice

When purchasing, check that all pigments are specifically labelled as epoxy safe to prevent problems during curing. For crisp line work, an ultra-high viscosity resin such as Art Pro Deluxe can help control pigment spreading. For deep volcano features, use a clear deep-pour resin and add the pigments gradually, mixing smaller batches to build colour intensity and avoid over-thickening.
