Before launching into your main epoxy project with red colourant, it is wise to test a small batch first. This practical step can spare you disappointment and wasted materials, especially when precision matters.
Why Small Batch Testing is Essential
Epoxy resin reacts with pigments differently depending on the base, pigment concentration, and even environmental factors. Testing a small amount first allows you to check the shade, transparency, and mixing behaviour of your chosen red colourant, so you can avoid unwanted results in your final piece.
- Assess intensity and opacity before making a large pour.
- Verify compatibility between your resin and the dye or paste chosen.
- Identify and tune colourant volume for consistent results.
How to Test Your Red Colourant
To perform a quick test, pour a miniature batch of your resin mixture, add your selected red pigment, and mix thoroughly. Observe how it blends and sets. If you are using highly concentrated options such as Colourfun liquid epoxy resin colourant, you’ll need only a drop or two to gauge colour strength. Let the sample cure fully to check for any unexpected changes in shade or clarity.
When This Matters Most
Small batch tests are especially important if you are blending custom shades, layering colours, or aiming for translucent effects, such as with the Magic Crystal or Colourfun sets. Even experienced resin artists rely on sample pours to avoid inconsistencies between batches or when trying new pigment types.
