First, we take plasticine (play-dough) the size of a small box. Then the jewelers press the plastic jewelry into the mold so that its imprint remains in the plasticine. This is how the mold, or matrix, is made. It’s needed to make the same pieces of jewelry afterward;
Now when we have the form, we fill it with hot wax. After the wax hardens we have a prototype of the item. We repeat this process for several products. When we have 5-10 wax pieces of jewelry, we create a “fir-tree” from these decorations. “Fir-tree” is a construction made of wax, which looks like a tree of the same name. It also has a trunk and “branches”, at the end of which we attach models of wax ornaments.
When our “Fir-tree” with prototypes of jewelry is ready, we immerse it in a casting-box. The casting box has a cylindrical shape and is empty inside. A special mixture is poured into this crucible, which gradually hardens.
So, now, in this box, we have a form and the “tree”, the trunk of which is in the upper part of the casting-box. That’s where we pour hot metal. As a result – the wax melts and evaporates, and its place is taken by metal.
