How to Cast Small Objects

Resin casting is a process where you pour a liquid resin into a mould to create a replica of an object, or encase an existing object in the material. Resin casting is also used to create jewellery, figurines, resin cast miniatures and other small objects. In this article, the team at Just Resin explores art resin casting and how to cast small objects, including the supplies you will need, and the process you should follow.

What Resin is Used for Casting?

Clear casting resin is perfect for creating jewellery, resin cast miniatures or other objects where transparency is desired. It is easy to use and versatile, making it an attractive option for many crafters. When used in conjunction with pigments or dyes, clear casting resin can be tinted to a wide variety of colours, allowing you to create unique pieces that cannot be replicated by any other material. The possibilities are endless when working with this product! In addition to its aesthetic advantages, clear casting resin also boasts excellent structural integrity. It has the strength and durability needed for long-lasting items such as jewellery or figurines while still remaining lightweight enough that they can easily be worn or carried around. This makes it ideal for creating highly detailed objects without worrying about them becoming too heavy or cumbersome.

What Supplies are Needed to Get Started with Resin Casting?

To get started with resin casting, you’ll need the following:

  • A mould: You can purchase silicone moulds specifically for resin casting, or you can use any food-safe mould that can withstand the heat of the curing process. If you’re using a food-safe mould, be sure to line it with a release agent such as mould release or even petroleum jelly to prevent the resin from sticking.

  • Resin: As mentioned above, the most common type of resin used for casting is epoxy.

  • Measuring cups: You’ll need measuring cups to mix the resin and hardener in the correct ratio.

  • Stir sticks: Stir sticks are used to mix the resin and hardener.

  • Gloves: Gloves are worn to protect your hands from the hazardous chemicals in the resin.

  • Safety goggles: Safety goggles should be worn to protect your eyes from the resin.

Resin Casting Application

Once you have all your supplies, you’re ready to get started!


  1. Begin by preparing your mould. If you’re using a food-safe mould, line it with a release agent.

  2. Next, measure out the resin and hardener using the measuring cups. The ratio of resin to hardener will vary depending on the type of resin you’re using. For Casting epoxy resin, the ratio is usually 2:1 ( two parts resin to one part hardener by volume ).

  3. Use the stir stick to mix the resin and hardener for 3 minutes or until it’s fully combined with any streaks.

  4. Pour the measured resin and hardener into the mould.

  5. Allow the mixture to cure for the recommended amount of time. The curing time will vary depending on the type of resin you’re using. Some can cure in a matter of minutes, whereas others will require up to 12 hours or more.

  6. Once the resin has cured, remove it from the mould and enjoy your new creation!

Casting small parts in resin has become popular amongst hobbyist

Resin cast miniatures have become increasingly popular among hobbyists and wargamers in recent years. This is due to their versatility, affordability, and robustness when compared to traditional metal models. Resin cast miniatures are made using casting resins which are then poured into a mould. Once the casting resin has cured, it can be sanded down for a smooth finish before being primed and painted. The end result is often a highly detailed miniature that looks just as good as one crafted from metal but at far less cost. Unlike standard plastic models, resin cast miniatures will not easily warp or break over time, making them ideal for those who want long-lasting models which can be used in both tabletop gaming scenarios or simply displayed on shelves as decorations.
