Super resistencia al calor: Starlite casero

Starlite is a material capable of withstanding high temperatures without flinching. It does not melt, and once removed from these high temperatures, it feels cool to the touch. It was invented by tailor and amateur chemist-inventor Maurice Ward (1933-2011) during the 1970s and 1980s. In 1993, it received widespread publicity thanks to the science and technology television program, Tomorrow's World. The Starlite material is named after a contemporary cartoon favorite of Ward's granddaughter, Kinberly. Despite interest from NASA and other major technology companies, Maurice Ward never revealed Starlite's composition, which remains unknown. After his death, neither his wife nor any of his four daughters have demonstrated any knowledge of the manufacturing process. Starlite was capable of withstanding a laser beam at a temperature of 10,000 degrees Celsius. The tests in which a raw egg coated in the material remained in that state after being subjected to a blowtorch flame for five minutes were very famous on television. On YouTube, it's easy to find videos in which Maurice Ward himself demonstrates the properties of his incredible material. Homemade Starlite is a formula we owe to Ben (I don't know his full name), the person behind the YouTube channel "NightHawkInLight."    / nighthawkinlight   The explanation of how this material is able to protect against these extremely high temperatures is more or less as follows: Heating the surface of this material causes the carbon in the cornmeal to burn, forming a carbon exoskeleton, the black part. This carbon exoskeleton is the result of partial combustion; that is, the cornmeal doesn't fully convert into carbon dioxide and remains as carbon on the surface. Charcoal is a very heat-resistant material: it can withstand temperatures of up to 3,550°C without melting. This layer protects the rest of the material and prevents the direct heat of the flame from completely charring it. Heating the bicarbonate in the mixture causes it to decompose into CO2, which pushes through the carbon exoskeleton, thus preventing the access of oxygen necessary for complete combustion. This outward expansion also further distances the flame from the unburned paste and protects the hand underneath. Source: Gemma Rabal,   / gemagoldie
