I have been bronze casting the profiles I prepared in wood earlier together with the round base plate for the new Plumage in Bronze sculpture. I made specific flasks for creating the sand molds from Delft clay. After closing the molds the profiles could simply be pulled out, leaving an empty space in the sand which I filled with liquid bronze. Therefore the bronze was heated to about 1050 °C in my oven made of ceramic wool. The results have become very nice, the profiles came out perfectly straight and with a high level of detail. Also the base plate turned out nice. I finished the surfaces by directionless sanding with 240 sanding paper, which showed to fit well with the natural appearance of casted bronze.

Although I prefer to sandcast my bronze sculptures in my own foundry, not all sculptures are suitable for sandcasting, especially when designs need thin sections and deep hollow cores. For the sculpture I showed on 16 january the pyramid shapes will have to be casted with the lost wax method instead. Therefore I have been making plates of wax, 4.5 mm thick, and used them to construct the pyramid shapes.
