How are custom objects made with epoxy resin?
Step-by-step guide for flawless casting and creative design
Creating unique handmade items with epoxy resin allows you to blend artistry and precision, resulting in anything from intricate jewellery to statement tabletops. This guide outlines the complete resin casting process, equipping you with clear techniques and essential tips to turn your ideas into durable, bespoke objects—all with a glass-like professional finish.
What You’ll Need
- “Trasparente” – Multipurpose Clear Epoxy Resin for Casting – Up to 2cm: Perfect for small to medium-sized castings requiring high clarity.
- “One-2-One” – Epoxy Resin for Handcraft, 1:1 Mixing Ratio: Great for beginners and crafters due to its easy mixing and glossy finish.
- “Liquidissima” – Epoxy Resin For Creations & Jewellery: Suitable for intricate moulds and fine jewellery items.
- “EpoxyTable 5-Five” – Deep Pour Epoxy Resin for Tables and Large Projects – Up to 5cm: Designed for large and deep pour projects such as wood tables.
- Silicone or plastic moulds, measuring cups, stir sticks, gloves, and protective clothing.
- Optional: colourants, fillers, glitters, decorative elements, and a heat gun or torch for air bubbles.
Step 1: Prepare Your Workspace and Mould
The key to successful resin casting begins with a clean, level workspace free of dust and debris. Use a sturdy table and protect surfaces with plastic sheeting or disposable paper. Ensure adequate ventilation when working with resins to minimise exposure to fumes and wear gloves throughout the process.
Carefully select your mould according to the shape and detail needed for your custom object. For best release, clean and dry the mould thoroughly; consider applying a compatible release agent if you plan to demould delicate or complex items. Check that the mould edges are well sealed to prevent leaks during pouring. Now, have all materials, including your chosen resin, ready for mixing to work efficiently.
Step 2: Mixing the Epoxy Resin
Precise preparation is essential for flawless results. Measure the resin and hardener strictly in accordance with the manufacturer’s ratio—some resins require weight-based measurement, while others (like the “One-2-One” – Epoxy Resin for Handcraft) are mixed by volume in a simple 1:1 ratio.
Pour both parts into a clean container, then stir slowly and methodically for several minutes, ensuring all traces are fully blended—especially at the sides and bottom. Take care to avoid whipping in unnecessary air, as this produces bubbles in the cured piece. If bubbles form, allow the mixture to rest before pouring or use a heat gun lightly for removal.
Step 3: Pouring and Layer Management
With your resin fully mixed, it’s time to pour into the prepared mould. For fine details and intricate jewellery, a low viscosity product—such as “Liquidissima” Epoxy Resin For Creations & Jewellery—helps resin flow into all contours without trapping air.
For custom objects larger than 2cm thick, layer management is crucial. Choose a deep pour resin (like “EpoxyTable 5-Five” Deep Pour Epoxy for thick artwork or tables), and pour in stages if needed to avoid excessive heat. Always pour slowly and steadily, working layer by layer if the volume or depth exceeds one pour’s recommended thickness. Remove any surface bubbles between pours for the clearest results.
Step 4: Curing and Demoulding
After pouring, cover your filled mould to prevent dust settling on the surface. Allow your resin to cure according to product instructions and ambient conditions. Standard curing times may range from several hours to multiple days, depending on resin type, thickness, and temperature. Rushing this phase can ruin your finish.
Once fully hardened, carefully demould your object by flexing silicone moulds or gently tapping rigid ones. Be patient—removing items too soon can lead to deformation or residual stickiness. Allow extra curing time if the object feels soft or tacky after initial demoulding.
Step 5: Finishing Touches
To elevate your creation, post-curing finishing techniques include sanding sharp edges, polishing surfaces to a mirror shine, or adding protective top coats. Clean your object with mild soap and water; avoid harsh chemicals that might dull the gloss.
If embedding objects or adding inclusions, ensure these are fully sealed and moisture-free before pouring resin to avoid clouding. Apply additional top layers if needed to create a perfectly smooth, domed appearance for art, décor, or display pieces.
Tips and Troubleshooting for Custom Resin Objects
Always measure your resin and hardener accurately. Even small ratio errors can cause improper curing—leading to sticky, soft, or brittle results.
Work in a dust-free environment to avoid imperfections. Cover your work while curing and minimise air circulation.
Watch for temperature and humidity extremes: cold can slow curing, while heat can accelerate and even cause cracking in thick pours.
Allow sufficient curing time between layers. Pouring additional resin onto a layer that is not yet firm can trap air bubbles or create uneven solidification.
Test colourants on small samples before full use. Some pigments or inclusions may affect curing or final clarity. Always trial mixed colours and effects before committing to a large, custom piece.

Frequently Asked Questions
Which epoxy resin is best for deep pours or complex moulds?
For objects up to 5cm thick, use EpoxyTable 5-Five. For detailed jewellery and small items, Liquidissima is most suitable.
How can I avoid bubbles when making custom resin objects?
Stir resin slowly, pour in thin layers, and use a heat gun or torch lightly to remove surface bubbles after each pour.
Do all epoxy resins use the same mixing ratio?
No, read the manufacturer's instructions. Ratios vary; One-2-One uses a 1:1 volume ratio, while others may require measurement by weight.
How long does epoxy resin take to cure for custom objects?
Curing times depend on product and thickness, generally from 24 hours up to several days for deep or large projects.
How do I achieve a clear, glossy finish on my resin projects?
Use high-clarity resins like Trasparente, sand and polish after curing, and keep your workspace dust-free.
Can I embed objects or images in custom resin objects?
Yes, as long as items are dry and clean. Secure in place and pour resin in layers for best clarity.
