Aluminium Oxide Ceramic Spark Plug. Ninja rocks are broken shards of spark plugs that are formed by smashing the ceramic portion of the spark plug with a hammer or other large object. Most spark plugs now use a 1 piece ceramic insulator made from purified alumina powder. The electrodes in a spark plug typically consist of high nickel alloys while the insulator is generally made of aluminum oxide ceramic and the shell is made of steel wire.
