Lost wood casting
I had a crack at something new today with amazing results. Lost wood casting. On a hunch I invested a magnolia seedpod in plaster/silica/glassfibre investment, burnt the pod out in a kiln and poured metal in the resulting cavity in the investment. For pictures of the result have a look hereI'm going to try this pod in copper and bronze next, and try casting a machine part this way. The photo's don't really show it but the detail is incredible.
