Using Silicone Moulds with Epoxy Resin 


Creating resin pendants using moulds and epoxy two-part resin is a quick and easy way to get started. 

Materials required:

Step 1: Wear PPE and prepare your materials

Before you start, make sure you have taken safety precautions. We recommend wearing gloves, glasses and a respirator. Make sure you also have the materials at hand. When working with resin, it’s important to be prepared as it is time sensitive. 

Step 2: Mix your resin 

Mix your resin according to the steps outlined depending on which resin you are using. If you purchased Aldax Crystal Cast Resin instructions can be found here: Using Aldax Crystal Cast.

Step 3: Pouring the resin

  1. Pour a small amount of resin into your silicone mould. 
  2. Add your inclusions 
  3. Pour the remaining resin to the desired depth. 


  • For jewellery pieces, you may not want to pour to the brim of the mould as the mould may be thicker than expected. 
  • If your inclusions float to the top or sink to the bottom (some glitters), you may need to add your resin in layers and wait for curing before adding another layer.

Step 4: Curing and demoulding 

Wait for your resin to cure. Don’t be impatient, otherwise, you may ruin your hard work! Once the resin has cured, carefully demould your pieces. 

Step 5: Sanding and polishing (optional)

If you didn’t fill your mould completely there may be sharp or rough edges. To smooth these edges out use coarse sandpaper starting at 180 grit before moving on to wet and dry sandpaper in grits starting at 320 moving progressively down to 1000 and 1500. To achieve a shiny polish, use a polishing cloth and a polishing paste for the final touches. 

Personal note: Sanding and polishing take up so much time and effort, it is very difficult to get that high gloss resin finish when sanding and polishing resin. Instead, use a nail file to smooth out the edges, then add another coat of resin to get that high gloss finish. 

Step 6: Assembling 

Now you have your pieces ready! Start assembling! Use jump rings, earrings hooks and hoops to make your own custom piece (if you’re creating jewellery that is). 

Step 7: Show off! 

Show off your creations! Be proud! Not everyone gets to say that their piece is custom. If you want an insta shout out just tag us! @poethan_au
