Chinese Chopsticks

Origin
On November 15, 2010, a fire, supposedly started by sparks from welding operations on the 20th floor, destroyed a 28-story high-rise apartment complex in Shanghai. At least 58 were killed in the fire and over 70 others were injured. One such victim was in the middle of eating lunch when the fire started, and the chopsticks he was using absorbed the heat of the fire, creating this Artifact

Effects
When tapped together, the chopsticks emit sparks that catch anything they touch on fire. The fire starts out small, but begins to consistently grow, soon becoming almost unstoppable
