This limited edition 400th Anniversary Classic Baseball Cap celebrates the origin of the secret Zildjian alloy. In 1618, Avedis I, an Armenian alchemist living in Constantinople, discovered a secret process for treating alloys and applied it to the art of maki ng cymbals of extraordinary clarity and sustain. This proprietary mix of copper, tin and silver is still used in Zildjian cymbals today. The alchemy symbols used in the design represent each of the metals in this secret alloy, arranged in the shape of a cymbal. This cotton hat has classic baseball cap styling and an adjustable snapback closure, making it the perfect fit for any drummer.
