How to Make Water Potable With Stone Age Technology

How to Make Water Potable With Stone Age Technology

1. Find some clay. It can usually be found near rivers, though in certain areas it may be the dirt that you're already standing on.
2. Find some wood. Pine is easy to get, but hard wood such as oak is a far better material.
3. Grind the wood into fine sawdust with a rock or other hard object and mix this dust with the clay.
4. Form the clay into a vessel, bowl, or something similar.
5. Allow the pot to dry completely.
6. Build a fire. Put the dried pot into it. Make the fire as hot as you can. The point here is to make sure that the clay undergoes a physical change, turning it into redware ceramic. Be patient, this can take as long as 24 straight hours of heat.
7. Allow the pot to cool.
8. Put water in your pot. Because it isn't glazed, the water will slowly seep through. The wood bits mixed into the clay will have burned off, leaving only a bit of carbon behind. The now porous ceramic will filter out dirt and other large pieces of matter that you may not want to drink.
