Can You Embed Metal or Plastic in Resin?

← Back to How do you put things under resin?

Embedding metal or plastic items in resin is a creative way to capture and display them in art, jewellery, or furniture. With the right approach, you can achieve impressive, long-lasting results.

Getting Started: Preparation and Suitability

Before adding any object to your resin project, ensure all elements are clean and completely dry. Dirt, grease, or moisture can affect the cure and appearance of the resin. With metals, most types embed well, though non-rusting and non-tarnishing options like stainless steel or aluminium are often preferred. Some plastics, however, may react to epoxy resins—certain types can discolour, warp, or lose clarity, especially if they’re sensitive to heat or solvents. Always test a sample piece if you’re unsure about compatibility.

Choosing the Right Resin for Embedding Objects

Selecting the right resin is vital for a smooth embedding process. For objects being placed within a layer up to 2cm thick, a clear casting epoxy such as “Trasparente” Epoxy Resin offers excellent clarity and is easy to work with for jewellery and smaller projects. For larger or deeper castings (up to 5cm or 10cm), consider a deep pour resin like “EpoxyTable 5-Five” or “Epoxytable 10-Ten” to accommodate and fully surround your items without overheating or introducing bubbles.

Practical Tips for Successful Embedding

Position your item securely before pouring—use a tiny drop of resin as an anchor and let it partly set before the main pour.
Pour resin in thin layers if needed, especially for larger or oddly shaped pieces, to avoid overheating and ensure a bubble-free finish.
If casting plastics, avoid using items that deform with heat or react negatively to solvents typically found in epoxy formulations.

When This Matters

Embedding metals or plastics is particularly popular in personal keepsakes, creative jewellery, wood and resin tables, and decorative art pieces where durability and clarity are essential.
