| Around the same time I was playing with lofting greyscale digital elevation maps to get 3D landscapes. I printed Acadia National Park (where I lived for a while) at a jewelry scale and printed it in their default "white, strong and flexible" material. I invested it and cast in Bronze. The dogma is that this material would not burn out cleanly, and you can see in the finished piece that it picked up a lot of surface texture that was not in the model. As I understand it one of the biggest problems with trying to burn plastics out of casting investment is that they swell when they get hot and/or expand violently when they get to combustion temperature and this can break fine details out of the investment or, as in this case, mess up the surface. | Around the same time I was playing with lofting greyscale digital elevation maps to get 3D landscapes.

| - | For this piece though the surface (shown in the inset) adds to the piece making the landscape look "real" (IMHO). I finished it with a brooch pin and ammonia-based patina. | + | For this piece though the surface (shown in the inset) adds to the piece making the landscape look "real" (IMHO).
