Using Silicone Moulds
Because they are made from water-clear silicone, our moulds (molds) they are ideal for all types of resin including UV curing resin. No need for polishing or sanding. We use a strong but flexible high quality silicone and each mould is hand made and checked.
Simply mix your resin with colours, sparkles, flowers or your clients’ elements or inclusions like breastmilk, lock of hair, umbilical cord and placenta or cremation ashes. Then add to the mould and cure in the usual way. Or you can add your resin to the mould before adding elements.
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. Although we use a food-safe silicone, we don’t recommend these moulds for use with food due to the manufacturing process.
Mould 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.
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 depression 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 resin cabochons are glued into place and ideally protected with a rubover bezel. You can use any setting with a 20mm depression and due to differences in manufacturing processes, we cannot guarantee a perfect fit. If you are unsure please order a single mould to test, make a test cast cabochon (see above) then test it in the bezel cup. To help you remove it from the bezel cup, place a length of dental floss over the bezel cup first before pushing in the cabochon.
