2 garden sculptures "Ricke and Rehkitz" by Helmut Diller, bronze sculptures in the set

Since ancient times the alloy of copper with other metals (especially with tin). Ideal, thousands of thousands of surviving metal for high -quality artificial castings. In the case of bronze, the artist usually uses a more than 5000 year old process, the wax outlawing process with lost form. It is the best, but also the most complex procedure for the production of sculptures. First, the artist forms a model of his sculpture. This is embedded in a liquefied silicone rubber mass. As soon as the material has been stuck, the model is cut out. Liquid wax is poured into the negative form obtained in this way. After cooling, the wax cast is removed from the mold, provided with casting channels and dipped into a ceramic mass. The ceramic mass is hardened in the fuel oven, the wax flows (lost shape). Now you finally have the negative form in which the approximately 1400 ° C hot bronze melt is poured. After cooling the bronze, the ceramic cover is smashed and the sculpture comes to light. Now the casting channels are removed, the surfaces are polished and patinated and numbered by a specialist by a specialist or according to his specifications. So every casting becomes the original.
