← Back to Why does a resin frame change colour?


Noticed unwanted colour changes in your resin frame? Mixing errors often play a key role in unpredictable outcomes. Here’s how mixing can affect your finished piece—and what you can do to prevent it.
How Mixing Errors Affect Resin Colour
Accurately measuring and mixing resin and hardener is essential. An incorrect ratio or incomplete blending can result in uneven curing, leading to unexpected colour shifts, cloudiness or streaks across the frame. These flaws often appear as dull or yellowish patches, particularly in transparent or light-coloured designs, detracting from the clarity and vibrancy of your resin art.
Products like “Icrystal” Clear Epoxy Resin are formulated for easy mixing, but even with high-quality resins, the fundamentals matter. Always follow the manufacturer’s recommended proportions and mix slowly until the mixture is fully combined, scraping the container’s sides and bottom to ensure consistency.


Tips for Faultless Resin Mixing
- Measure precisely: Use digital scales or marked cups for accuracy—guesswork risks imbalance.
- Mix thoroughly: Blend for 3–5 minutes, paying attention to all parts of the container to avoid pockets of unmixed resin or hardener.
- Check for clarity: Mixed resin should appear uniform and free from streaks before pouring.
- Consider your working environment: Work in a dust-free, dry space at a temperature recommended by the resin’s instructions.
Ready-to-use resin kits, such as the “Trasparente” Epoxy Resin Kit, include all key components, making accurate mixing easier for beginners and professionals alike.
When This Matters Most
If you’re aiming for a crystal-clear, high-gloss finish or incorporating subtle pigments, even minor mixing errors can spoil your results. This is especially true when showcasing your work on display bases like the Stretched Cotton Canvas on Wooden Frame, where every flaw is more visible.
