In 1997, a woman named Patricia Billings received a patent for her invention called Geobond. Geobond is an indestructible and fireproof material. Patricia Billings was a sculpture artist. She tried to invent a material that was indestructible. After almost two decades of basement experiments, she created a solution that when gypsum and concrete were added made a material that was indestructible but also fireproof. Geobond is currently selling in more than 20 markets worldwide. Patricia Billings is now living in Kansas City.
