Primitive technology is a hobby where you build things in the wild completely from scratch using no modern tools or materials. These are the strict rules: If you want a fire, use a fire stick - An axe, pick up a stone and shape it - A hut, build one from trees, mud, rocks etc. In this video we will build a hut from fired clay bricks and mortared them together with a cement made from wood ash left over from the firing process.
