In this case, the clay is dug on site and a truck delivers and dumps the ash near the pile of dried clay being readied for use.
The clay and ash are mixed, water is added and, in this case, the mixture is shoveled into a mold where the formed tiles made with the mixture will dry for days before being put into the kiln.
After the drying these and other styles of dried tiles and blocks will be loaded into the kiln and fired.
