Quick Answer
In urban areas, source clay from abandoned construction sites, sidewalks, and drainage systems, and refine it through mixing and sifting to create a workable consistency. Be cautious of contaminants and heavy metals. Consider collaborating with others to find and process clay.
Identifying Potential Sources of Clay
When searching for clay in urban areas, look for construction sites, sidewalks, and drainage systems. These areas often contain clay-rich soils that can be extracted and refined. Be aware of potential contaminants such as heavy metals, industrial pollutants, and other hazardous materials. Wear protective gear, including gloves and masks, when collecting and processing clay to minimize exposure risks.
Refining and Processing Clay
Refine the collected clay by mixing it with water and then sifting it through a fine-mesh screen to remove any debris or contaminants. The ideal ratio of water to clay is 1:1, with adjustments made as needed to achieve a workable consistency. This process helps to create a clay mixture that is suitable for coil construction and pit firing.
Tips for Working with Urban Clay
Urban clay often requires additional processing steps due to its higher concentration of contaminants. Consider adding natural materials, such as sand or sawdust, to improve the clay’s workability and reduce its tendency to crack. Additionally, be mindful of the clay’s moisture content, as this can affect the firing process and the final product’s durability. To waterproof your primitive pottery, apply a natural sealant, such as beeswax or plant resin, after firing.
