Making Silicone Moulds

Please use a pourable liquid silicone rather than a putty. You can use opaque, translucent or water-clear silicone for use with epoxy resin. To use UV resin you will need to use water-clear silicone so the light can penetrate. We recommend SORTA-Clear by Smooth-On in the USA, we have trialled other silicones but they don’t have the strength and can rip. A shore hardness (sh) of 18 or 20 is ideal but for soft moulds you can use sh15.

How to Use A Charm Bead Mould

You can read our full blog here on making a lock of hair and rose petal charm bead with all the links for the products you’ll need. Here’s the YouTube tutorial video

If working with UV resin we recommend you work in layers to achieve beautiful depths of colour.

These moulds are suitable for use with resin (UV resin, EcoResin, epoxy resin or polyester resin), concrete, polymer clay (air drying, heat curing such as Premo and Sculpey). We recommend removing the polymer clay from the mould before baking if not using air drying clay although they can be heated up to 130°C. To remove unset clay without warping it, we recommend cutting the mould vertically around halfway down. Although we use a food-safe silicone, we don’t recommend these moulds for use with food due to the manufacturing process.

Large Bead Mould Masters Life and Care

These moulds are sold for semi-permanent use and will degrade with use. This is normal and not classed as a fault. Please see our mould care information for more info. The life of your moulds will depend on the material used, the number of uses, how gentle you are using it, good storage, careful washing and environmental factors. The mould masters should be wiped gently after each use with a damp cloth, dried and polished before use with a lint-free cloth.

Test Cast

It is very important you do a test cast with each mould to check for imperfections, to remove any dust attained during transit and to make sure you are comfortable using the mould before making any jewellery. We advise you use UV resin for this and coat the inside of the mould in resin before curing, removing and making a visual check. If there is a problem with the test cast please get in touch within 7 days of receipt.

Settings and Findings

We recommend that you do not overfill the mould but allow a little extra resin in the pouring spout for bubbles to rise and to provide a grip to remove the cast. You can usually trim the excess before sanding, dome with resin if required. Large Bead Mould Masters are good for our glue-in heart inserts and our glue-in thin bead inserts.

Size fluctuations

The charm bead cores are never going to be 100% central as they’re made from glass/precious stone masters that are handmade. They may not be totally uniform, some may be up to 1mm larger or smaller in any direction than our guidelines. Whilst making charm beads at Tree of Opals over five years, I’ve literally never had a complaint about a core being off-centre from a customer, and these are the moulds we use for dozens of orders a wee in that business. If you require a guarantee of perfection please order from another supplier who can guarantee it, sorry.

Ideal for use with our solid silver large charm bead inserts!
