Essential Tools and Safe Setup

Set up your workspace with care to avoid dust and debris contaminating the resin. Use gloves and protective gear to keep hands clean and ensure safety. An organised environment helps prevent accidental spills or rushed steps during the project.

Step 1: Prepare Your Work Area and Mould

Begin by clearing your workspace and covering all surfaces with disposable plastic or newspaper to protect against spills. Ensure the room is dust-free and at a stable temperature (typically between 18–22°C) as temperature influences curing. Select and inspect your silicone mould — it should be clean, dry, and free of dust or debris. For very intricate or new moulds, a light release agent can ensure demoulding is straightforward, though most silicone moulds do not require this step. Place your mould on a perfectly level surface to achieve even vase walls and prevent resin pooling to one side.

Step 3: Pour the Resin into the Mould

When pouring, do so in a thin stream from a slight height, which further minimises bubbles. Do not exceed recommended casting thickness. For most clear resins, thicker layers may trap heat and distort clarity or cause cracks. If your mould is deeper than the resin’s recommended limit, pour in multiple stages, allowing partial curing in between, to achieve the correct thickness safely and with clarity.

After pouring, inspect the mould for air bubbles. Lightly mist the surface with isopropyl alcohol spray to burst surface bubbles, or use a toothpick to remove stubborn trapped bubbles near the edges. Work quickly—resin begins to gel after the working time ends.

Tips, Common Mistakes, and Troubleshooting

• Pouring resin too thick in one go can cause overheating, resulting in yellowing or distortion. Layering is safer for deep moulds.
• If bubbles persist, check room temperature, mixing technique, and resin freshness. Warmer temperatures and slow mixing help eliminate most bubbles.
• Avoid water or moist objects in moulds—trapped moisture causes cloudiness and weakens the resin.
• If you see dents or sticky spots after demoulding, the resin likely wasn’t mixed well or wasn’t given enough time to cure.
• For colourful or shimmering effects, use high-quality mica powders; always check compatibility with your chosen resin.

Finishing Touches and Display Ideas

Enhance your finished vase by polishing the exterior for a glass-like shine, or combine with dried flowers for a unique statement piece. Position under natural light to highlight its clarity.
