Last year, I sent some #clay that I collected to the University of West Georgia Archaeology Dept and they just sent me the results of their experiment. They tested how the addition of sponge spicules (or fired sea sponge) affects the strength of the fired clay. This method of tempering clay isn't common but evidence of its use can be found in pottery shards throughout the world, including here in SW #Florida. Anyway, how cool to be able to assist in scientific #research.
