Spiky rubber jewellery constructed from shards of rubber with decorated coloured beads, sometimes with metal, twisted and knotted, giving a feeling of delicacy yet rusty impression. Mould rubbers contain a high concentration of natural rubber. They are capable of reproducing the finest jewellery. High elasticity allows the mould to separate cleanly from the metal master pattern and its plastic memory allows the mould to regain its exact shape.|
The mould rubber jewelleries are soft and flexible, allowing the wax patterns to be easily stripped from the mould, increasing productivity. This flexibility enables difficult moulds to be made with heavy undercuts when stiffer rubbers would break the wax pattern. Jewelleries made from rubber will last many years, retaining their elasticity and matte look.
