The big benefit of this method is that usable clay can be extracted from the most marginal of soils. The clay shown below was processed from soil that was almost 70 percent sand and, using other methods, would have been considered unusable. For this exercise we started with 10 pounds of dirt that had a marginal clay content. It would barely ...

Clay is a type of fine-grained natural soil material containing clay minerals. Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural …

At approximately 2385-2420 deg.F the SiO2 begins to turn from solid particles and crystals into molten SiO2. In the heating process the organic material in the clay is burning off, the water is evaporating, and gaps are being created. However, at the point of many compounds turning more viscous/ or closer to liquid, gaps are also being filled.
