Lost wax casting dates back to the 5th and 6th centuries BC. The process consists of making a wax casting from a mold, which nowadays in most cases is made of silicone, which has been previously made on an original. Subsequently coating the silicone to give it greater uniformity.

Once the wax is melted we will proceed to fill and empty the mold between 2 and 5 times, depending on the thickness we want to give the piece, once the piece is in wax we will proceed to place the channels through which the metal will enter and the gases will be expelled, once this is done we will place the piece inside a cylinder and we will cover it with a refractory slurry.

Subsequently, the wax is burned off, which is why this type of casting is called “lost wax casting”. The process consists of introducing the molds in an oven also called muffle, and increasing the temperature progressively until reaching 750 º C, at this temperature the molds will be kept for 24 hours, until its complete drying and burning of the wax. After this time we will place the molds to be filled with metal.
Once the crucible is loaded with ingots, we will turn on the furnace, which will reach approximately 1200ºC. Once the metal is at its optimum melting point, we will proceed to fill the gap left by the wax when it burns, in order to shape the piece.
Once this is done, we will break the outer coating to be able to remove the figure and proceed to its subsequent finishing.
