Why Test Coloured Resin on a Small Sample First?

Test on a Small Sample Before Committing to Your Main Piece

Adding colour to resin can transform your creative projects, but diving straight into your main piece can risk unwanted surprises. Testing on a small sample first ensures reliable results and helps you achieve the perfect finish.

Why Sample Testing Saves Your Project

Resin behaves differently depending on the colourant and technique used. By making a small test pour, you can observe how your chosen dye or pigment interacts with the resin, including factors like transparency, saturation, and blending. This simple step often highlights issues, such as separation or an uneven finish, allowing you to make quick adjustments before working on your main artwork.

How to Conduct an Effective Resin Colour Test

Start by mixing a tiny amount of resin, then add your selected colourant according to manufacturer guidance. For example, Colourfun liquid colourants are highly concentrated and only require a few drops to achieve a strong effect. Pour the coloured resin into a disposable cup or silicone mould. Let it cure fully, then observe the outcome—check colour depth, clarity, and surface quality before applying the technique to your main pour.

When This Matters Most

Trying a new brand or type of colourant
Achieving a specific shade or transparency
Using unfamiliar resin combinations or techniques

Testing saves time and precious materials when attempting detailed effects, such as layered ‘sea’ gradients or transparent gemstone looks.
