Bronze Onto Aluminum

I wanted to put up some of last year’s experiments since my work is now moving into more experimentation of combining materials. Here are some images of an experiment where liquid bronze was poured onto pieces of solid aluminum. The mixture was treated in different ways; stirring, allowing to melt, and preset forms. You can see the way some of the pieces allowed the aluminum to maintain its integrity and other methods pushed the aluminum into the bronze solution.

Due to no degassing, the Al has a number of holes. With little agitation, the two metals only surround each other and do mot mix. Bottom: There was a great deal of stirring in this piece. When polished, you can see the cooling pattern in the bronze.

As the metals cool, the shrink. Sometimes the pattern looks like plastic shrink wrap if left untouched. Bottom: The two metals mixed nicely on this piece. The Al is locked into the bronze and did not flake even with polishing.
