Gypsum is one of the most ubiquitous and easy to find rocks on the planet and we’ve been mining it for thousands of years to use in art, medicine and construction. The Egyptians even used it for their pyramids! This week at the Freedom Farm permaculture Homestead Off-Grid in Spain we’re using gypsum that we mined on our own property to make plaster of Paris with the end goal of making a homemade DIY emergency survival plaster cast. Hopefully we never have to use it for real but at least we know how!
