Understanding the types of resin and the spectrum of colour options available is essential when planning a casting project. This mini-guide will walk you through core resin choices and how to create the colour effects you envision.
Common Resin Types for Casting
Two main categories dominate resin casting: epoxy resin and polyester resin. Epoxy resins offer clarity and self-levelling properties, making them suitable for projects like coasters, trays, and river tables. Polyester resin cures quickly and is often selected for its cost-effectiveness and suitability for decorative items. It’s important to select a resin type compatible with your intended application; for example, kits like the River-Table Complete Kit include both shallow (2 cm) and deeper (up to 5 cm) pour options to match different project needs.
Choosing and Mixing Colours
Colouring resins adds personality and artistic flair to your castings. Popular choices for tinting include pigments, resin pastes, and powder-based colourants. Opacity and intensity can be controlled by the amount added—start conservatively and build up. Effect pigments like metallic or pearl can create visually stunning results. Always check that your colourants are compatible with the specific resin type you’re using to avoid issues with curing or finish.
When Colour Selection Really Matters
Colour choice can strongly influence the final appearance, especially for items like tabletops, jewellery, or functional art. Consider the setting where the finished piece will be displayed and the mood you wish to evoke. Test colour blends in small amounts before committing to a large project, as some tones may appear differently once cured.
