I should get paid for researching on the internet… I don’t know how I do it, but I almost always seem to find what I am looking for, sometimes it happens like this time, while looking for something else, I run across something that I have been previously trying to find. Today, while looking up another person who writes on off-grid subjects, one of her articles turned out to be exactly what I have been looking for, a way to make your own terracotta pot for a water filter, this has an actual recipe for the clay, you don’t need a kiln (a MAJOR plus!) and I believe most people would be able to do this. Here is the article, it can be found here https://off-grid.net/2008/06/19/cheap-water-filter-for-everyone/

Cheap Water Filter for Everyone
The Australian National University (ANU) scientist Tony Flynn has developed a process to create water filters from commonly available materials. The materials need to also be fired, which can be done without a kiln or other western technology, by using common manure.An estimated 80% of all sickness in this world can be attributed to unsafe water and sanitation according to the World Health Organization (WHO). That can be seen in the annual 1.5 billion episodes of diarrhea in children under the age of 5, with about four million of those being fatal.Since historically water filters have had to be imported to developing nations, which means increased cost and reduced availability for the populace. With the new filter design made from common place materials available in even the most remote places.“These filters are a hollow ceramic vessel filled with charcoal. They are intended to filter out suspended silt and bacteria. However, at around $US5 each, they’re too expensive for individuals in many developing communities to consider purchasing,” stated Mr Flynn. “They are very simple to explain and demonstrate and can be made by anyone, anywhere. They don’t require any Western technology. All you need is terracotta clay, some used coffee grounds or tea leaves, a compliant cow and a match,” Mr Flynn continued “Everyone has a right to clean water, these filters have the potential to enable anyone in the world to drink water safely.”Filter production is simple:
- A handful of crushed dry clay
- A handful of common organic material, such as coffee grounds, rice hulls, or used tea leaves
- Add water, just enough to make a stiff biscuit dough like mixture
- Shape into a cylinder shaped pot closed on one end
- Dry it in sun
- Place dried filter on a layer of
