Antimony, 51, Kitchener-Waterloo Collegiate Institute and Vocational School, Kitchener, ON

Antimony: In my tile I used pencil crayon only. I tried to include a lot of the symbolism about the element; easily the most noticeable one is the Egyptian eye in the middle. This was included because historically, ancient Egyptians used stibnite (antimony and sulfur) to line their eyes. Within its iris is a shape representative of the rhombohedral crystal structure of antimony. The flames at the bottom relate to its modern usage as a flame retardant. The swirls of green and the skull and bones pertain to the toxicity of antimony when ingested or left on the skin, but primarily when inhaled.
