Our NONOS sculptures are partly cast in bronze.
For a smooth cast, the model must be carefully sanded smooth.
A sand casting mold is created and this is then filled with hot aluminum. For the bronze casting we use the lost wax technique. The principle of this procedure has been known for thousands of years and has been found at the latest since the 4th millennium BC application in the metal trade. Today, for example, the hood ornament of the Rolls-Royce (see Spirit of Ecstasy) is made using the lost wax process. All important bronze art works of the early Middle Ages were created in this way. This process is also used in contemporary art, as the impression exactly reproduces very fine modeling structures.
The new sculpture “Sky” is still in its sand bed and is carefully removed. The procedure destroys the form and is therefore called the lost form. It is finely sanded in the studio and given a beautiful silver patina. This makes it insensitive to touch.
SCULPTURES FOR PARKS AND PUBLIC SPACES
Works of art have to withstand a lot more in public than in private. That is why it is important that we can also offer our customers the possibility of receiving a cast sculpture in any size that can withstand not only the weather, but also human influences. So it is possible to place our works of art in the middle of the city, in public gardens, parks and promenades. Our sky is the beginning that shows us how a NONOS can appear as a cast figure. In the future, however, we can also imagine sculptures 10-15 feet high.
FOR THOSE INTERESTED: HOW DOES THE SAND MOLDING PROCESS WORK?
In this process, as the name suggests, forms made of sand are used, which are destroyed after a single use according to the principle of the lost form. For the mold, an impression of the object to be case is made in sand. The liquid metal is then poured into the cavity, where it solidifies and can be processed further after it has been released from the sand mold. The sand of the destroyed for can then be reprocessed and used for new forms.
Our partner in the creation of Sky was Becker Guss in Vienna. Wolfgang Krismer from Imst and Heinz Plain from Trier are at our side for bronze.
