How We Make Jewellery – Creating a Wax Ring Model Tree

As some of you may be aware, Steven Stone is a rare jeweller that manufactures al jewellery inhouse from start to finish. So straght from the initial design of the jewellery, creating a wax 3D model, casting into a prrecious metal to the final finished piece. One of the middle processes, which we will show you in today’s post, is to create a “wax tree” of jewellery pieces to turn into a mould to be cast. Before every jewellery piece is made it’s designed on the computer to be printed into a wax 3D version.

Lost Was Casting Process

wax tree for jewellery making Each wax model has a “sprue” attached, which is basically a stick of wax. The sprues are used to connect the wax models on a “tree” of wax, which is a thick straight cylinder wax rod. Each model is welded to the stick, to form a tree like object. Once the tree is finished and all the wax jewellery models are attached, it’s placed into a metal cylinder, known as a flask, so that a plaster substance, combining investment powder and water can be poured over to create the moulds. The whole process is called ‘lost wax casting’. The Flask of wax models is then but into an extremely hot oven over night so that the detail of the wax pieces is captured in the mould as the wax is absorbed. metal cast of jewellery
