Are Your Resins Mixed by Weight or Volume?

Getting your resin mix right is crucial for jewellery making, as the proportions determine both the finish and durability of your creations. However, not all resins use the same measuring method. Here’s what you need to know about mixing by weight or volume.

Understanding Resin Mixing Methods

Most two-part epoxy resins used in jewellery making require mixing by weight. This means you’ll need digital scales to measure out exact amounts of resin and hardener according to the product’s recommended ratio, ensuring optimal curing and finish. Precise weighing helps avoid sticky or improperly cured results. However, some resins—such as One-2-One Epoxy Resin—are formulated for a straightforward 1:1 ratio by volume. With these, you simply use equal parts from each bottle, making them especially beginner-friendly and reducing the risk of error.

Choosing the Best Measuring Technique for Your Project

Always check your resin kit’s instructions. Mixing by weight is often regarded as the most reliable method for consistent curing and clarity, particularly if using highly precise or quick-curing resins such as ICreation Fast Epoxy. If you prefer a less technical approach or are getting started in resin art, consider a 1:1 by volume formulation like One-2-One or a complete starter kit such as the Evershine Collection. These offer a simple pour-and-mix experience without needing scales, which suits most hobby crafters and small jewellery projects.

When This Matters: The Impact on Craft Results

Getting the proportions wrong can lead to soft, tacky, or cloudy resin pieces. The choice between mixing by weight or volume becomes important when working with different brands or types of resin—especially in crafts where accuracy matters, such as creating gifts or selling handmade jewellery. Follow the guidelines for your chosen product to achieve clear, durable, and attractive results every time.
