← Back to Where to buy resin for costume jewellery?


When creating costume jewellery, choosing a resin with a long working time can make the difference between rushed casting and precise, beautiful results. This feature is especially important for artists and makers working with intricate moulds or detailed designs.
Why Does Long Working Time Matter?
A resin’s working time refers to how long it stays fluid after being mixed, allowing you to pour, shape, and adjust your designs before it sets. For jewellery makers, a longer working time lets you add pigments, place embellishments, or eliminate bubbles without the pressure of a race against the clock. This is particularly useful for elaborate or complex pieces that require careful attention to detail.


Best Resin Types for Extended Working Time
Epoxy resins with low viscosity and extended working times, like the “Liquidissima” – Epoxy Resin For Creations & Jewellery, are well-suited for intricate costume jewellery. These resins flow easily into fine moulds and allow additional time for colour mixing and bubble removal. For easy preparation, some options like the “One-2-One” Epoxy Resin offer a straightforward 1:1 mixing ratio, making them user-friendly for both beginners and experienced crafters.
Practical Tips for Using Long-Working-Time Resin
- Prepare your workspace and tools in advance to take full advantage of the extended open time.
- Measure your components accurately for the best finish. Some kits, like the “Evershine Collection”, come with accessories and guides to help with precision.
- Work in layers if your mould is moderately deep (up to around 1 cm) to ensure even curing and clarity.

When Long Working Time Is Most Important
Extended working time is especially valuable when your design involves several steps—such as layering colours, embedding items, or working with larger numbers of small details. It gives ample opportunity for creativity without feeling rushed.
