Had an earthenware clay body drip into a puddle on kiln floor. Of all the places searched on internet, perkolator's comment in this thread helped me the most: using needle tool to poke and prick all around the hardened puddle - it worked! It only took an inch or so of kiln brick - 1/4 inch deep. I am very lucky that the mass didn't spread to the element. Thanks, perkolator!!
