How Much Epoxy Resin Do I Need for Jewellery and Crafts?

Getting the right amount of epoxy resin is essential for jewellery and small craft projects. A precise calculation means less waste and smoother results every time.

How to Measure Your Mould’s Volume

The easiest way to determine how much resin you’ll need is by measuring your mould’s internal volume with water. Carefully fill your mould to the intended level with water, then pour the water into a measuring jug to check the volume required. Make sure to dry your mould fully before pouring in resin.

Mixing Ratios for Accurate Results

Many craft resins are mixed by weight, but for ease in jewellery making, a 1:1 resin like One-2-One is perfect. You simply mix equal parts resin and hardener by volume—so if your mould holds 20ml, you’ll need 10ml of resin and 10ml of hardener. Always follow the instructions for your chosen product.

Tips for Small Craft Projects

Prepare a little extra resin to account for drips or spillage, but avoid mixing too much as most resin has a working time limit.
Avoid overfilling the mould, which can cause unnecessary waste and makes finishing harder.
Work on a protected surface and use disposable mixing tools for easier cleanup.

When This Matters

Accurate resin calculation is particularly important for one-off or custom moulds, where wasting material is costly. For beginners, it also reduces the chance of mixing errors and disappointment.
