Among the many uses for zinc, boosting the immune system to fight the common cold is possibly the most commonly known.

This bluish-silver metal is also used for rust protection, die-casting, and many other medical purposes. The use that was most compelling to me, however, was as a sustainable building material.  A zinc roof can last 100 years (compared to a few decades for asphalt shingles) and is much less likely to wind up in a landfill compared to traditional roofing materials because zinc can be recycled indefinitely without loss of physical or chemical properties. As a nod to how eco-savvy zinc can be, this piece includes some recycled elements of its own, including scraps of old neckties and wrapping paper.


Antimony (Sb) – #51

When this metal is added to lead and tin, it creates an alloy that can be poured into molds to create crisp, hard, reusable letter forms for printing – a little invention that Johann Gutenberg liked to call movable type. I created this piece by doing a rubbing of my children’s wooden blocks with Shiva paintstiks to look like lines of type and using some fabrics with a metallic feel.
