For thousands of years, casting aqueous substances and drying them into usable forms has been a core technique in manufacturing, and one of the greatest advancements made in human technology. From ceramics and metals to glass and plastics, countless methods of casting have been invented to exhume objects from molds over the millennia. But unfortunately,…
