Bronze is so traditional in sculpture that it has named an era and does not require further explanation. There was little change in the casting process in recent centuries. Some standardization in the metallic alloys and in the industrial waxes, the use of silicone and fibers replacing plaster to make the molds and for smaller pieces the use of vacuum pipes, increasing the precision and allowing bigger contrasts of volumes and thicknesses and decreasing the retouches.

I have also been working more directly with pure copper in plates, wires and tubes. Cutting, hammering, welding and binding with blowtorch, filing and polishing, which allows me to reach compositions, materials and textures that would not be attainable from molds. In addition this procedure allows a direct and immediate contact with the metal and with the finished sculpture, generating unique pieces of great intensity, where each millimeter was considered and worked on.
