strength of the ceramic water filter materials as a function on clay and organic materials like sawdust, ash etc. have been performed. Economics and supply chain would have to be assessed before considered CWPs as a solution to a water problem. Comparative cost analysis, efficacy and operation effectiveness of low cost clay-based water filters has been extensively reviewed, but results are difficult to generalize due to variability in the materials and recipes used.

185:. A filter workshop was set up in 1999. This workshop developed into an independent business that has implemented more than 40,000 filters in collaboration with several NGOs. PFP takes pride in the fact that it does not operate any filter workshops, but instead trains local potters to produce and distribute the filters.
303:
The manufacturing process is quite simple. A press forms the pot shape out of clay mixed with rice husks. The pot is fired, and the husk burns, leaving small holes that the water can run through. Finally the filters are coated with colloidal silver. The filters are used with plastic storage units

Nicaragua. The potters met with a female pottery/canning cooperative. This led to the first PFP fundraiser in Washington, DC. The program began to gain momentum after the Nicaraguan civil war to help pottery cooperatives. In 1988, the first contact in Nicaragua was made. A year later

PFP has been active with several programs in
Nicaragua since 1989. These programs emphasize the mission of PFP to help local potters succeed in their own right. Many of these projects center around helping potters market their products locally and abroad (PFP help organized an 18,000 piece sale to

potters to travel in their country and abroad by providing transportation and expenses. Additionally, PFP finances scholarships for apprenticeships and holds conferences that bring together both
Nicaraguan potters and also international buyers which help potters learn how to market their products

The long-term sustainability of CPWs has also been assessed. It has been found that the CPWs have a disuse rate of 2% per month, with 67% of this disuse resulting from filter breakage. This leads to a mean usage lifetime of 2 years. This may or may not be appropriate for a given situation. The

Efficacy of the CPW filters also depends on the flow rates through the filter. Lower flow rates have led to disuse of the filter. It is found that a filter manufactured with a clay to sawdust volume fraction of 1:1 was found optimal for field use. An elaborate study illustrated that the flow rate

Potters for Peace is clear to assert itself as an assistance organization, rather than an aid-based organization. Instead of simply solving the problem, PFP aims to provide sustainable solutions propelled by the goals of the individuals they work with. According to the

140:"Our goals are to offer support, solidarity and friendship to developing world potters; assist with appropriate technologies sustained using local skills and materials; help preserve cultural traditions; and assist in marketing locally, regionally and internationally".

Potters for Peace has a materials research facility in
Nicaragua where different combinations of ceramics are tested for their different properties for the Ceramic Raw Materials Research project. Also, PFP pays some of its potters to do their own materials research.
279:
Pieces made by these local potters are marketed in several ways. PFP developed a system of road signs that alert people to the availability of pottery. Funding is given for these potters to attend artisan fairs, where they show their wares and make connections.
