An artist makes a model in wax, clay or some other material
2. Making a mold
According to the model, a rubber mold is made, usually made in 2 or more parts
3. Wax
Melted wax is poured into the mold and a hollow wax casting is obtained
6. Installation of metal casting channels and air extraction
The channels are installed so that the molten metal can reach all parts of the casting
5. Finishing the wax casting
Traces of the joints are smoothed and the wax model in this phase gets the final look, the look that will have a metal casting
4. Wax removal
A hollow wax impression is removed from the mold which can then be reused
7. Making a casting mold
After installing the casting channel and air outlet, the wax casting is coated with a refractory mixture or bay into a refractory form, made of gypsum, ground brick and already used and ground refractory mixture
8. Drying
The wax casting is dried for a minimum of 72 hours at a temperature of 650 degrees Celsius until the wax melts in a refractory form and a cavity is obtained which, with its shape, accurately reproduces the wax casting
9. Metal casting
Molten metal (bronze, aluminum, brass…) is poured into the mold cavities that reproduce the wax casting
12. Installation in the intended place
11. Chiselling, ie. finishing of castings
Castings are cleaned, joined by tig welding as a whole and irregularities are sanded, and everything ends with patination of the joined casting or sculpture in order to achieve the required color (patina)
10. Breaking the mold and removing the casting
After casting, the mold cools and breaks and releases the raw metal casting
