some of the triassic sandstone recovered from the quarry was excavated from a building site that had been cut into the rock surface. this exposed the strata formations and enabled me to extract material that was in a pristine state - having not been exposed to the environment since triassic times - no pollutants had affected the sandstone.
adding these triassic materials into the clay becomes a continuation of their own geological journey. as part of the throwing and firing techniques, they go through processes of extraction, suspension and compression and through periods of heating and cooling.
