The technology of manufacturing of jewelry involves the use of wax. Why the need for jewelry wax and how to use it? To answer this question, we need to know the stages of creating jewelry.
The manufacture of the wax model
Before the finished decoration will appear before the eyes of the Creator or customer, takes a long time. The sketch of the future jewelry master jewelry first creates a wax model on which the manufactured form of a piece of jewellery. Early cut from the wax model wizard, had to manually. With the advancement of technology came the ability to mechanize this procedure. Made from wax product is made form for casting. Then wax vytaplivaete, leaving emptiness. In the finished form already filled with the precious metal and after solidification the product is sent for final revision.
The process of creating a model in wax is called a stencil. Thanks to the technique of stencil products are cast with fine details. Modern technologies allow to produce jewellery wax for modeling geometrically complex patterns that are impossible to do manually. For this purpose, special machines, allowing you to replicate the product and perform the most delicate work.
The composition and properties of jewelry wax
For stencils use a special material. It is of several types. The main properties that should have a high-quality wax:
- sufficient strength after hardening to withstand the post-processing of small parts;
- should melt without residual ash in the annealing process;
- the surface is made of jewellery wax models should be flat and smooth and should not stick to forming materials;
- the melting point should not exceed 100 °C and the softening temperature not below 35°C.
In the fundamentals of jewelry wax is a natural or synthetic material with the addition of chemical components required to modify the mechanical properties. The composition of the wax affects the following properties:
- hardness and softness;
- mechanical memory;
- the fluidity in a molten state;
- interaction with the forming material;
- the speed of solidification;
- melting point.
Depending on the purpose, the jeweler chooses to work needed a wax. There may be occasions when the master mixes several types, for example, naplavlena on the rod of a soft wax for modelling small parts of a material of greater hardness.
The types of wax
There are two types of wax for jewelry: casting and modeling. Wax modelling is more durable, it is solid as a tree. It can be drilled, planed and sanded on the machine, even the smallest details are solid. Foundry wax softer plastic to work with it does not require a machine to cut the shape can be a minimal set of tools. Small parts of this wax is more brittle, often casting wax is used for stencils. With foundry wax recommend to start running beginners, as it more plastic, pliable and melts faster.
