What is the Maximum Depth for a Clear Pour?

Why Does Pour Depth Matter for Clarity?

Each clear epoxy resin formula is designed to cure safely at a specific maximum depth per layer. Exceeding this recommended thickness can cause excessive heat build-up during the curing process. The result is often cloudiness, yellowing, or trapped bubbles – all of which affect the pristine, transparent look that many makers seek. Referring to your resin’s technical guidelines is crucial for both safety and finish quality.

Recommended Maximum Depths for Common Clear Epoxies

• Up to 1 cm: For fine jewellery and small castings, use a resin such as Liquidissima for a flawless, water-clear finish.
• Up to 2 cm: General casting projects benefit from Trasparente, ideal for decorative and artistic pours
• Up to 5 cm: For river tables and large block castings, EpoxyTable 5-Five is formulated for deep, clear layers without compromising transparency.

If you need to achieve greater thickness, it’s best to pour in multiple layers – allowing adequate curing time between each – to preserve clarity and avoid overheating.

When This Matters Most

Maximum pour depth is crucial when you require a high-quality finish, such as in statement river tables, jewellery, or display pieces where any yellowing or bubbles would be highly visible. Following the depth recommendations gives you the best chance of achieving a crystal-clear outcome every time.
