Create Lava Flow in Resin Using Heat

If you’ve ever seen art that looks like molten lava oozing across the surface and wondered how did they do that — here’s your answer It’s all about heat control

The lava flow effect is bold dramatic

and perfect for adding movement and contrast to your pours And the best part You don’t need any fancy additives Just pigments and a heat tool

Here’s how to create lava flow effects in using heat like a pro

What Is the Lava Flow Resin Effect

The lava flow effect in mimics the swirling glowing patterns of hot molten lava flowing over stone You’ll often see bold color transitions with dark and fiery tones blending into one another like they’re still in motion

The trick lies in using heat to move and separate the pigments in a way that creates natural flow patterns

Materials You’ll Need

Two part epoxy 

Heat resistant surface or mold

Pigments like black red orange gold or neon yellow

Heat gun or torch

Mixing cups and stir sticks

Gloves and protective gear

🔥 Optional Use metallic mica powders for extra shimmer or alcohol inks for vibrant contrast

Step by Step How to Make a Lava Flow Effect in Resin

1 Mix Your Resin Thoroughly

Follow your brand’s instructions for mixing Mix slowly to reduce bubbles and make sure the ratio is accurate This is key for proper curing later

2 Divide and Add Color

Split your mixed into separate cups and add different pigments

Black or deep red for base

Bright red orange yellow for lava glow

Metallics or pearl for shimmer

Stir each color well until smooth

3 Pour Your Base Layer First

Start by pouring your darkest color onto your surface Spread it out gently to create a base This will serve as the “rock” or shadow underneath the lava

4 Add Lava Colors in Layers

Pour the hot colors like red orange and yellow in ribbons or waves on top of the base Try not to over blend These lines are what heat will push into flowing patterns

5 Apply Heat Strategically

Now the magic begins Use a heat gun to move the lava colors gently across the surface Aim for directional flow

Sweep heat back and forth to spread the color

Use short bursts to create curls or wave shapes

Get close for movement further back to smooth

Avoid overheating or the resin may scorch or cure too fast

6 Let It Cure Undisturbed

Once you’re happy with the movement let your  piece cure completely in a dust free space Most cure in 24 to 72 hours

Resist the urge to keep adjusting after it starts thickening or you may lose the effect
