By adding fine sawdust to the clay mixture, the form is able to kill harmful bacteria. The sawdust burns during the firing process so the shell is porous and water can filter quickly. The drops which collect on the bottom seep through the holes to the outside. By additionally adding colloidal silver, the filter kills bacteria and increases the shelf life of the filtered water.
“Pure filtering is an aesthetic demonstration of the water’s transition from turbid to clear, turning the process into something fascinating magical and valuable”
