Petriska worked with many metals, casts and alloys. His main and most notable works were in silver and silver nickel, bronze, steel and mixed media (bronze, aggregate & fibre-glass), as well as fountains and outdoor garden sculptures.   Petriska's sculptures are on public display and made into awards.  Petriska also made smaller bronze works & replicas of his sculptures, and would usually carry around and give to politicians and influential individuals, as a reminder to be more concerned about our surrounding environment and the role we play in natures balance.
