Tips for using thermochromic pigments in resin crafting

Measure Precisely

Accurate measurements are essential in resin crafting. Use a reliable scale to measure both the resin and the thermochromic pigment to ensure consistent results.

Mix Thoroughly

Blend the thermochromic pigment into the resin thoroughly, making sure there are no clumps or streaks. A slow, gentle mixing process can help prevent air bubbles in the epoxy resin.

Control Temperature:

When pouring resin, ensure that the temperature is within the specified range for the thermochromic pigment to activate.

Practice on Smaller Projects

Before attempting larger, more intricate creations, practice on smaller projects to get a feel for how the thermochromic pigment interacts with your specific resin and in different temperature conditions.

Seal and Protect:

Once your project is complete, seal it with a clear resin layer to protect the thermochromic layer. This will help preserve the color-changing effect and enhance the durability of your creation.

Remember that experimentation and practice are key to achieving the desired results with thermochromic pigments, so don’t be afraid to try different techniques and temperature variations to get the effect you want.
