Resin jewellery is gaining popularity by the day. Making jewellery is just one of the ways resin casting is used. Some of the other uses are in the making of industrial or medical prototypes. People also use resin casts to make small models or toys.
If we look at the chemistry behind the resin casting, the principle behind it is the thermosetting of the monomer. In the liquid state, the plastic is in monomer state, and as it solidifies and hardens it gets converted to a polymer.
Many jewellers have moved on from using natural resins, and use good quality epoxy resins. After hardening the resin becomes more durable, and doesn’t chip on its surface. Although casting resin is almost transparent when it is made, but with age it assumes a yellowing colour. Normally the resins used to make rings and other pieces of jewellery are given colours by using mineral refined pigments.
If you are trying to make rings using epoxy resin, the first thing to do is start off making simple ones. That will help you become familiar with the working of these chemicals. One of the easiest to start with are the epoxy resins. The reason for this is that the hardening and solidification of epoxy resins takes place slowly. That would give you enough time to mix the liquid well and add the things that need to be added.
But before adding other elements to the mix, you need to start off by making something that is simple. For example, if you are making metal bezels, you can just pour the mix into your reservoir and then wait for it to set.
Once you are comfortable with resin mixing and setting, you can move on to using additives in your mix. The easiest way to do this is to use non-porous additives. These could be glitter, beads or other metal chips. They can add colour and beauty to the final product.
The basic procedure for making rings and other resin jewellery is to make the resin mix along with additives while it is in the liquid state, and then pour the viscous liquid into the mould. The mould needs to be made of non-reactive metal which has a higher heat absorption capacity. Generally the resin is left for 24 hours before it attains full hardness. Jewellery made by this method helps you make attractive and durable rings.
