What this industry manufactures
Jewellery and craft workshops cast pendants, earrings, rings, keychains and small decorative pieces in silicone moulds, often embedding dried flowers, mica powder, glitter, small objects or pigment within the resin. The same small-batch casting technique extends to paperweights, coasters, bottle openers and other tabletop decor pieces cast in rigid or flexible moulds.
Why Clear Casting Resin is suitable
Small-batch jewellery casting is well within Epoxy Clear Casting Resin's verified 30 mm depth limit, so unlike a river table, the depth restriction is rarely a practical constraint here — most jewellery moulds are far shallower than that. What matters more at this scale is fine detail reproduction and a genuinely bubble-managed pour: its 900 cPs viscosity flows into mould detail without being so thin that it wicks under embedded objects, and its 40-minute pot life gives enough working time to mix a small batch, pour it carefully, and torch or heat-gun any surface bubbles before the resin starts to set. Its crystal-clear, high-gloss cured finish and UV-stabilised, yellowing-resistant formulation suit pieces meant to be worn or displayed over time.
Required resin characteristics
- 01Fine detail reproduction in small silicone moulds
- 02A pot life long enough to mix, pour and de-gas a small batch before it starts to set
- 03Crystal clarity that doesn't obscure embedded flowers, mica or small objects
- 04A viscosity that wets embedded objects without excessive wicking underneath them
- 05UV-stabilised colour retention for pieces worn or displayed under regular light
Manufacturing process
Silicone moulds are usually used as-is, though a light mould-release spray can help with detailed or rigid moulds. Epoxy Clear Casting Resin is mixed 2:1 by weight with Epoxy Hardener, stirred thoroughly, and poured slowly from a slight height into the mould rather than dumped in, which reduces the air introduced during pouring itself. For pieces embedding flowers, mica or small objects, a thin base layer is often poured and left to gel slightly before the object is placed and a second pour covers it, holding the object in position rather than letting it float. Surface bubbles are released with a heat gun or small torch passed briefly over the pour; some makers pour in small increments — a little resin, check for bubbles, torch, then continue — rather than filling the mould in one go, particularly for detailed or multi-layer pieces. Once cured, pieces are demoulded, and any mould-line seams are wet-sanded and buffed back to a high-gloss finish.
Advantages
- 900 cPs viscosity flows into fine mould detail without excessive wicking under embedded objects
- 40-minute pot life gives enough working time for careful small-batch pouring and bubble release
- Crystal-clear, high-gloss finish suited to pieces meant to be worn or displayed
- Same 2:1 mixing and cure system as larger casting work, so technique carries over directly

Frequently asked questions
Rarely in practice — most jewellery and small decorative moulds are well under 30 mm deep, so the depth limit that matters for larger work like river tables is not usually a constraint here.
Pour slowly from a slight height rather than dumping resin into the mould, then pass a heat gun or small torch briefly over the surface to release any bubbles that rise. For detailed or multi-layer pieces, pouring in small increments and checking for bubbles between pours gives more control than a single full pour.
Yes. A common technique is pouring a thin base layer, letting it gel slightly, placing the object, then covering it with a second pour — this holds the object in position rather than letting it float to the surface.
It uses a UV-stabilised formulation that resists yellowing significantly better than a standard, unstabilised epoxy. No clear epoxy is permanently immune to gradual colour change under prolonged, intense UV exposure, so pieces worn or displayed in direct sun for years may still show some change.
The same way as a larger pour — resin and hardener are weighed on a scale at a 2:1 ratio by weight, not measured by volume or eyeballed, since accuracy matters as much for a small batch as a large one.
Both are 2:1 epoxy systems suited to small castings. Epoxy Clear Casting Resin is the more general-purpose casting choice; Epoxy Art Resin is formulated specifically for self-levelling flatness, which matters less in a contained silicone mould than it does on an open table-top surface.
