Ignition of corn starch caused a dust fire at a water park in New Taipei City, Taiwan, killing 15 people and injuring more than 400 others.

Cornflour, cornstarch, maize starch, or corn starch is the starch derived from corn (maize) grain. The starch is obtained from the endosperm of the kernel. Corn starch is a common food ingredient, often used to thicken sauces or soups, and to make corn syrup and other sugars. Corn starch is versatile, easily modified, and finds many uses in industry such as adhesives, in paper products, as an anti-sticking agent, and textile manufacturing. It has medical uses as well, such as to supply glucose for people with glycogen storage disease.
